Vista on Portege A100 - Can I update the BIOS?

Question: Vista on Portege A100 - Can I update the BIOS?

Had a go at installing this, and all is fine apart from installing the Value Added Package - the main thing I want to get working is the function keys for screen brightness and connecting a TV.

I understand that upgrading the BIOS can help getting the VAP installed ( I get the ID ERR NOTINSTALLTVALZ message), I know that Toshiba are not directly supporting the A100 for Vista but is there a BIOS I can install that will work? I'm thinking there might be a similar machine that works in Vista or maybe just an A100 BIOS that will suffice?

Many thanks!

Preferred Solution: Vista on Portege A100 - Can I update the BIOS?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Vista on Portege A100 - Can I update the BIOS?


May I ask where did you found the Vista Value Added Package for Portege A100?
I didn?t find this Value Added Package on the Toshiba Europe site.

There are only 3 files for Vista. One of the files is BIOS v1.60-WIN which seems to be OS-independent.

Regarding the BIOS;
You should know that the BIOS update is always risky.
If you will use wrong BIOS version or wrong BIOS update procedure you can damage the motherboard!!!
?and as you probably know the motherboard is one of the expensive notebook parts!!!
It?s not worth to trying something which can damage the notebook. You know?

I have an Old Portege A100, Model: PPA10A-0002LP, but I can't seem to find that model on any Toshiba website, closest I've seen is the " PPA10A-0002L".

I'm wanting to see if there's a BIOS update that will allow me to Boot from a USB Device.

The issue I am having is that I need to reinstall Windows, but the CD ROm cant read discs.
It does Network Booting PXE, but i'm new to this sort of thing and have absolutly no idea what to do there.

Any help would be great,


Answer:Portege A100 PPA10A - Will BIOS update allow to boot from a USB device


Portege A100 seems to be developed only for Australian market.
As you said there is a Portege A100 PPA10A-0002L model number listed on the Toshiba Australian page but the Portege A100 PPA10A-0002LP belongs to the same series which is PPA10A.
So in my opinion the BIOS should work too.

Anyway, I doubt that the BIOS update will add any further booting options.

Usually the BIOS support the booting from CD/DVD drive, HDD, LAN and USB FDD.
It should be possible to boot from a bootable diskette using an USB FDD drive.
I doubt you would be able to boot from USB ODD since this Portege A100 supports an internal CD/DVD drive.

Hi Guys,

My laptop (few month old) decided to die and I have been told by tech support that it could be due to the BIOS. The problem is that the computer will not start the OS (Vista) and the only available BIOS update is the windows version. Is there any other mirror to get the traditional update or even some way to convert the Windows BIOS update to a boot disk?


Answer:Equium A100-338 will not start the Vista OS - Bios update?


If you can see only one BIOS version on the Toshiba page then only one version exists and is available!!!!

> The problem is that the computer will not start the OS Vista
I don?t think that BIOS could be responsible for such problem.

You should firstly provide more infos about this issue!!!
Does the notebook pass the Toshiba welcome screen?! Did you try to recover the notebook with the Toshiba recovery CD?

Please provide some details!

Now I'm installing all the Tosh Vista drivers. According to the instructions, the first thing to do is to update the bios.

So, I download the bios (v3.60) from the site and run the .exe, but it tells me I need the common modules.

The only common modules I can find on the Tosh site are for XP.

Hello Jon

As you know Vista is officially not lounched and I presume on notebook manufacturers site the driver is still not available.

If you can identify which WLAN card is inside of your notebook check manufacturer support page. Usually they offer this stuff earlier as PC or notebook manufacturer.

Answer:Satellite A100 - Windows and BIOS doesn't start after BIOS update

Do you see the Toshiba logo?

Was there a power failure when you updated the BIOS?

Try removing the battery and AC Adapter, and leaving it for a couple of hours. You could also try reseating the RAM.

If that doesn't help, you may need to send it to an Authorized Service Center for repair.

Hello Lukas

Unfortunately there is no public document about that but if you check some other topics you will see that latest version fix some graphic problems and it is confirmed that latest version fix this successfully.

I don?t know why your latest BIOS update was unsuccessfully but when you make BIOS update please be sure that there are no external devices connected and very important is that it must be done with AC power supply only and not with battery power supply. Before you start with BIOS update please check Info how to do this.

I just wanted to upgrade my old Satellite A100-386 with 4gb RAM (2x2Gb Crucial) instead of 1Gb, as I am now under Windows7 Pro 64bits instead of the original XP 32.

I read I had to upgrade the BIOS as mine is v2.00. So, I downloaded the last one.
It seems to be an automatic BIOS upgrade (S10V600.exe) as mentioned on Toshiba Website.
But when hit the .exe, I have an error message box telling me :
"LOADPEDRV.EXE: failed to start the service"

My question is: Do I need to be 32bits OS to run the automatic BIOS upgrade or is ther any way to flash the BIOS with a Windows7 64 bits OS running?

Thank's a lot for any answer as I did not find "how to" in research mode on this furum.

Best regards

Answer:Satellite A100-386 - How to update the BIOS?

Hi FPSim,

Who says that you have to update the BIOS just for RAM upgrade? The maximum RAM capacity is depending on mainboard and chipset and not BIOS.

On official Toshiba website I saw that the model supports 4GB RAM so BIOS update is not necessary. Upgrade the RAM and everything is ok.

You can download another version of the same bios-update here : PR10U

This file contains more information about performing the update, see the readme-file
you can either do a direct update within XP or make a bootable diskette or a bootable CD

If the "direct update" within XP won't work, you will need at least an USB-fdd-drive, most of them are recognized easily by the bios ( hold F12 during start-up and choose fdd )

Answer:BIOS Update not possible for Portege M700


It seems that Vista OS was preinstalled on this notebook.
This means that you have installed the Win 7 system at your own hand.

The point is that BIOS update requires some essential Toshiba tools.
For example the Value Added Package is important software and should be preinstalled on the notebook.

Is VAP installed?
If not install the VAP before trying to update the BIOS.

Some forums says that the solution is updating the Bios. I have a Bios update v.1.60 ready for install. When I try to install, we get the message "the battery power is not enough".

My power cord is always connected. If I disconnect the power cord, laptop is off.

Please, what can I do?



Answer:Portege Z835 - need help with BIOS update

To be honest I don?t think it is BIOS related issue. As far as I know battery should be charged even if the notebook is OFF so why BIOS update if battery cannot be charged at all.

For me it sounds like hardware related issue.

How old is your Portege?
Is warranty still valid?

Maybe you should contact Toshiba service and ask for help or even their opinion.

Also booting from this USB floppy wont work. Is this a problem related to this specific USB floppy drive (it's a NEC)? Are there any other procedures to update the BIOS?


Answer:BIOS Update on a Portege 3490

Hello Thomas

I am not sure but I assume that your unit has no USB legacy support and, as far as I know, you can do it using original Toshiba FDD. Check please your BIOS settings.

I am pretty sure that you will not be able to make BIOS update using your FDD.

I have been wrestling with this device for a while now and I seem to be progressively making the situation worse.

My current issue is that I can no longer access the BIOS after changing a setting in the BIOS that related to USB emulation (or something like that). I was in the process of trying to make the device boot from a USB and pretty much twiddling with every setting to see what would work.

This one didn't. And now the device no longer responds to F2. It's like it is ignoring the keyboard. Doh!

Is there some way to roll back or re-flash the BIOS? Or another way to access it? I tried an external keyboard, to no avail.

How did I get here?

Well ... I was given this device to put back to factory condition and I could not find an obvious option that would do this, other than the Toshiba Maintenance Utility which looked hopeful. It offered to erase the partition (which at the time seemed fair enough) - BUT THAT"S all it did - so the machine just repeatedly boots, displays "Please insert system disk" and then reboots.

OK, I'm an idiot - but it does seem silly for Toshiba to offer an option that instantly bricks the machine?

Anyway, I've moved on from that problem to one that is significantly more dire. Not being able to access the BIOS means I don't have any options - unless one of you wonderful people can help me discover one.


I have since discovered that the next setting I was going to adjust - the Secure Boot setting - may have solved... Read more

On the nordics toshiba website they have the 1.50 version available for download, while the US version website I can download the newer 1.60 version.

I have a Portege 3440CT with bios version 1.50.

Is there any way to place the BIOS file on a small hard drive, and boot from that?

Ideas, anyone?

Answer:Bios update on Portege 3440CT.

Sorry CyB but I really do not understand you. If you check Toshiba support page you will find two BIOS updates. Both of them must be done using FDD. So now I am asking myself why you try to do it under running operating system. Sorry but it is really ridiculous.

Toshiba provide two different BIOS updates. One is TRAD (must be done with FDD) and WIN (can be done under running WXP or now Vista). For old notebook models there is no WIN version.

Is there any way to place the BIOS file on a small hard drive, and boot from that?

As far as I know something like this is not possible and you can check eBay and obtain FDD. You can get it for few bucks. It is really not expensive.

I have Satellite A100-233 PSAA8E-05J02ETE notebook and I tried setting up LAN and wireless driver but I can't.
Can anyone give me drivers? I tried Toshiba support drivers it did not. That driver can not work

OS: Windows XP Pro SP3

And when I tried BIOS update and load new BIOS: ok
Analyze old and new BIOS compatibility: ok
Read old BIOS: ok
Save old BIOS to backup file: ok
Flash new BIOS cant start and 1-2 min after notebook freeze

i resolved.

but really did not fun..

if you using A100-233 PSAA8E-05J02ETE model notebook you must use A100-PSAA8A driver very funny..

Answer:Satellite A100-233 - Freezes during BIOS update


I think in this case you have to go to an authorized service provider. If the notebook did freeze during BIOS update the ROM module must be reflashed.

On the Toshiba website you can search for nearest ASP and download all drivers. Check this: > Support & Downloads

I have just updated my BIOS to version 6.0 as TOSHIBA says >> 26/11/07 "This Bios Update adds increased functionality to your system : Satellite A100 (PSAAN) 6.00-WIN Toshiba.

My original BIOS was 5.9
My computer works fine A100-33 But when my computer restarted it showed the BLACK Screen;

I noticed that it displayed BAD CHECKSUM and suugested I select the default BIOS but I *ignored this advice* as wanted this new BIOS Version.

What does BAD CHECKSUM mean and what effects will this have on my computer peformance please if any?

Under system Info this is displayed for my BIOS Version/Date Phoenix Technologies LTD 6.00, 12/07/2007

OS Name Microsoft??® Windows Vista Home Basic

Answer:Satellite A100 BIOS update - BAD CHECKSUM


don?t worry if the message "bad checksum" only appears once.

"Bad checksum" means that the BIOS was modified, rewritten or the settings were restored to default. So, every time you save your bios settings, the bios makes a "checksum" to verify on the next boot that the settings were kept and everything is alright. If something goes wrong or was modified then the stored checksum from the last save don?t match the actual new generated checksum.

So if you perform a bios update, all your settings will be modified so - logical - you get an "Bad Checksum" error.

Another reason for such "Bad Checksum" is a empty or malfunctioning BIOS battery, so the BIOS cannot keep it?s settings and you will get everytime you boot the machine a "Bad Checksum" message.

Good day, I have two questions about Portege 3410.

The first one: I cannot update BIOS (there is 1.50 in use, I want to update to 1.60). The instruction does not work: I connect Teac USB-drive on USB-port, switch USB-FDD emulation to Enable, switch notebook On with F12 pressed, the message "Ready to update BIOS..." appears, I presed key, but nothing happend. What's wrong?

The second one: I cannot install Windows XP on to notebook (it does not boot neither FDD-USB, nor External DVD-USB).
How can I install Windows?

Thank you.

Answer:Portege 3410 - How to update BIOS and install XP?


Just one question: Why do you want to update the BIOS? Is it really necessary?
I ask this because this update is always a little bit risky and you could damage the ROM module.
Anyway, have you tried to load default settings in BIOS before you start the update and install XP?

You can install XP without CD. Therefore you must copy the i386 folder on the HDD from another computer and some booting files for HDD? I think you should search a little bit with Google to find workaround for this. You should find enough! ;)

Greetings all,

Portege R830-138 Current BIOS 3.7

I am unable to update the BIOS to either 3.8 or the latest 3.9 version. Error: This Computer Is Not Supported.

VAP is installed and modules are working. A previous forum post suggested that it may be related to the recent Intel Management Interface firmware update which I had applied and am unable to uninstall or rollback.

Any suggestions?


Answer:Portege R830 - BIOS 3.9 Update Error


A friend of mine has updated the BIOS from 3.7 to 3.9 without any big problems.
It could be possible that you cannot update the BIOS because of the missing or disabled TVALZ services.

Go to Control panel -> Administrative Tools icon and click services.

Here you can check if the TVALZ service is available ? if its available, enable it and then try to update the BIOS.

If this will not work, you will need to recover the notebook using Recovery HDD or Recovery disk? The BIOS update should functions using the Toshiba factory settings

However, as far as I know the VAP (value added package) needs to be up to date to get BIOS updated?. Also the firewalls and other security and antivirus software preinstalled on the system should be disabled before trying to update the BIOS.

Hi there,

My Portege A600-13Y BIOS is version 1.50:

- should I upgrade to 2.00WIN?
- I found this source for the biso upgrade 2.0 but there is no indication that this file is authentic TOSHIBA bios.
No checksums, no ssl certificate, nothing. Is it possible to get it in a secured / authenticated way?

Thanx for answers,

Answer:Re: Portege A600-13Y: BIOS update 1.50 to 2.00-WIN - How risky it is?


First of all you should use and download the BIOS files only from Toshiba website.
The Portege A600-13Y PPA61E is a Toshiba European notebook model and all the drivers and BIOS can be found on the Toshiba driver page.

I don?t know why you ask for the checksums or ssl certificate? the Toshiba websites are safe?
but everyone who needs the drivers or BIOS can download it?

You should only ensure that you have chosen the right notebook model and that you have downloaded the right BIOS!

But why you want to update the BIOS?
If your notebook is running troublefree then a BIOS update is not important? I follow always this advice; never change a running system.

HI, I have Portege M700 - 116 with Vista Ultimate SP1. And I download a fresh BIOS (P005Bv160.exe) from [] version 1.60-WIN date 10/10/08. When I try to install it I have an error window said:

Unsupported product type is installed.
BIOS Package BIOS version: Ver.1.60
Current BIOS version: Ver.1.50

So my question is... WHATS WRONG?? What a product type? This BIOS update is OS independent and language independent (world wide), so i think many people with M700 will have the same problem. Is it some problems with previous version of BIOS? which I downloaded from the same site month ago. I dont understand, the BIOS installer for Windows was made to make the process easy, but it does not even work...

Answer:Portege M700 - 116 BIOS Update Error


I see you are using the Vista Ultimate.
I doubt this is an original preinstalled Vista version.

The error message: Unsupported product type is installed says that the product (software OS) which is preinstalled is not supported by BIOS. I think the error is related to the preinstalled Vista Ultimate. Possibly the BIOS cannot be updated running Vista Ultimate.

SO it would be very interesting to know if you can update the BIOS running Toshiba preinstalled OS.
Should check this!

Hi Roro,

Yes you have to install Windows XP to update the BIOS but my question is: Is this update necessary or just for fun? BIOS update is always a little bit risky and should only be done to solve problems. If your computer runs properly I wouldn?t make this update.

I don?t know if this update is possible on Virtual XP but I wouldn?t try it. If the update fails you need a new ROM module or mainboard. I think the BIOS update isn?t designed for Virtualization mode?

I'm having some issues with my GF's Satellite A100 (PSAA8A). I accidentally, while installing a new HDD with a clean install of XP, flashed the BIOS while installing the drivers. Its kind of bricked now.

Using a CD Bootdisk, combined with the V6.00 BIOS update, I can get to a DOS command prompt but am uncertain where to go now.

Under *Tradional BIOS Update*
See link : [ IOS&FID=TRO0000000b07]

It says :
+1. Extract the zip file containing the BIOS upgrade to a temporary folder.+
+2. In the temporary folder three sub folders will be generated. "docs", "Update - 3,5' Disk", "Update - CD-R or CD-RW"+
+3. Insert a formatted 1.44MB diskette in the floppy disk drive.+
+4. Execute the *.exe file in the folder "Update - 3.5' Disk". Follow the instructions on the screen. A BIOS update diskette will be generated.+

But there are no 3 folders. There is only one called S10VWF which contains Winphlash etc (see pic url). As far as I'm aware I can only run Winphlash in a Windows environment due to its GUI. So what do I do? Help!!!!!

Answer:Re: How to run BIOS update from DOS prompt - Satellite A100 PSAA8A?

Hi Brett

There is a tiny thing that you have forgotten or overviewed.

The BIOS which you have downloaded is a ?WIN? BIOS version. It?s not traditional BIOS update!!!

The description posted in your posting describes the update using traditional BIOS.
But Toshiba driver page provides only the WIN-based BIOS updates. Such BIOS can be upgraded only from running Windows OS.

Please don?t mix these both updates possibilities!!!!

Hi all,

But at restart, it doesn't go through the boot process. I can't access the boot menu nor anything else by clicking on F2 or F12. But could go to the detailed process by clicking on escape. And there I see the following messages:
Phoenix TrustedCore(TM)

No TPM or TPM has problem.
1023M System RAM Passed

And that's it.
I can't get hold of older BIOS versions, and I couldn't find the version of the V6.0 updater which I could put on a CD for another BIOS update.

Anyone has an idea on what's wrong? And if you confirm it's to do with V6.0 and I'd need an older version, please could you send me the necessary setup files to do the update through a CDROM.

Thanks for your help.

You can try to remove the battery and AC/DC adaptor, then wait 1 hour. After this connect both devices again and try to start the notebook. Maybe it does work.

If not I think you need help from a notebook technician. It seems that the ROM module must be reflashed or something else.

ACPI -> Advanced Configuration and Power Interface
ACPI defines hardware and software interfaces that enable OS-directed configuration and Power Management to enumerate and configure motherboard devices.
For example: ACPI is needed for the stand by and hibernation mode.

Now to you question; the new BIOS was updated and configured for VISTA usage.
It seems the VISTA was not compatible with the previous BIOS version because of the ACPI interface. Now you can install the Vista on the notebook but it seems you will need an driver. Possibly new chipset driver release could help. But as you probably know, the drivers are not available at this time. Unfortunately?

Being kind of tech swavy, i know my chances are very low in fixing this but here goes.

I decided to update the BIOS on my Toshiba Satellite A100-TA7(PSAA8C-TA702C) laptop to the latest version available (6.00).

I did this because I've heard of people have better luck in making their FN keys work in linux with the newer BIOS.
The installation finished normally(went through all the steps, wrote all 21 blocks) without any errors but after rebooting I noticed that it now hangs at the Toshiba logo screen.

The blue progress bar moves twice but then gets stuck about 1/3 of the way through.
In order to see how bad the damage was, I pressed esc at the beginning of POST and saw that it gives me the right BIOS Version (6.00).

It also tells me that "No TPM or TPM has problem", and "2039M System RAM Passed."
It then displays the message "Press <F2> to enter SETUP" (which makes the message disappear, but otherwise does nothing.

If i press f2 during the Toshiba logo screen, it replaces the message at the bottom with "Please wait" and nothing happens even after waiting an hour.
(Which makes sense because before the whole blue bar would load before going into the CMOS settings). The thing is that the BIOS doesn't really "freeze", It just gets stuck at one specific place (I know this because i can press F2 even after waiting an hour and the laptop does respond to it by displaying "Please Wait".

It?s very long story and it sounds not good?

I wonder about your BIOS version? as far as I know the notebook series was designed for Canadian market; it?s a Canadian series and the BIOS or drivers should be downloaded from the Toshiba Canadian website!!!
Wrong BIOS could cause a issues like this one described it your message above!!!

>I did this because I've heard of people have better luck in making their FN keys work in Linux with the newer BIOS.
Toshiba FN buttons need Toshiba driver and fact is that Toshiba driver pages don?t offer the drivers for Linux distributions? so I don?t believe to the story propagated by any people.

I don?t want to write a long story so I would cut this now;
Fact is that something went during the BIOS update procedure.
Either you used a wrong BIOS or wring update procedure and therefore the notebook cannot pass the POST?

You have to contact the local ASP to solve this? maybe you are a lucky guy and the technician has to flash the ROM module again? but in worst case your mobo is damage and needs to be replaced. :(

I obtained the correct file from Toshiba (bios-20080325071859 containing P0058v160.exe), but when I try to run the application it fails with "This computer is not supported".
I have checked several times that I downloaded the file for the R500....

Can anyone help?

Answer:Cannot make BIOS update for Portege R500 (PPR50E)


That?s strange.
Did you change something on you installed Vista?

In different cases the BIOS cannot be updated because some essential tools like common modules for Win XP has not been installed.
If you are using vista you don?t need Common Modules but I recommend reinstalling VAP.
Then you should try to run BIOS update again.

Otherwise use the recovery disk and set the notebook back to factory settings.
After the notebook has been set to the same state like at the first day of purchase, you could run BIOS update.

I recently updated the BIOS on my z30c pt263e as per advice from the toshiba update application installed on my PC.

Since that update, my LAN (wireless) and bluetooth have been behaving abnormally, including:
Connecting to various wireless networks, but not being able to access the internet. In order to do so, I have to do a wireless troubleshoot in windows, which resets the wifi adapter, then it works againIf I switch between networks (say a wireless, to a hotspot wireless on my phone) it does the same thing. Will connect to the network, but not access the internet, necessitating the same resetBluetooth has started to work abnormally at the same time, including saying my bluetooth keyboard is paired, but it won't recognise any input from my keyboard.

I've since downloaded and reinstalled both the LAN and Bluetooth drivers from the Toshiba website. This has NOT fixed the problem.

If toshiba is not aware or not going to do anything about this, can someone please post a link to the previous BIOS version (which isn't available when I search on the EU support site) so I can at least verify if it was the BIOS update causing the problem

Could anyone post the immediate prior BIOS for z30c PT263E. The one recently released (24 January) seems to have resulted in me having new Wireless networking, and bluetooth problems.

my PORT?G? Z930-118 failover and wont start after i upgrading in middle of upgrade i remove power and press shutdown bottom after that i see the power and wireless but screen still black ?

Any help please

Answer:Portege Z930-118 wont start after BIOS update

Hmmmm.... BIOS upgrade interruption has screwed up BIOS and that?s the reason why your notebook doesn't start properly. BIOS is damaged now.
In such case you need professional help by authorized Toshiba service provider.

On this forum you can find many threads about similar problems. Some people have tried to fix this alone and if you are interested to read how one other forum user has fixed it check please this thread.

Ayway, you can contact nearest Toshiba service, explain the situation and ask for help.

Hi there.

I manage an IT company, and some of our equipments are portege z930.

We use Linux as the main OS, and in order to use all HDD space, we've erased Windows partition.

How can I update BIOS from a Linux operative system? I asked in an official technichal support company, and they told me they use an special linux live CD handled by Toshiba.

I don't know if I can get this live cd somehow. If not, I'd like to know how to update our Bios without having to reinstall Windows OS.

Thanks in advance!

Answer:Portege Z930: How to update BIOS having LINUX/UNIX OS

As far as I know on BIOS download page Toshiba offers Windows version only. Generally speaking Linux is not supported at all.
Try to contact nearest Toshiba service provider and ask for help. Maybe they can obtain such special CD.

By the way: why you didn?t prepared machine (BIOS update) before you have started to install Linux?

Hello Forum,

i have exactly the same problem as described here, 2 years ago:

I need to update my BIOS, but i cant because the BIOS Updater tells me that Intel-TXT is enabled.
Unfortunatelly i cant disable it in my bios. Its just not selectable. The "cursor" just jumps over it.
I can only "Hide" it which doesnt help.
I have the same for the VT-d and VT-x setting in the BIOS. This is not selectable or changeable as well.

TPM isnt enabled though...
I installed the infineon suite and it tells me that i need to enable TPM in bios to use it. :-(

I have an very old Bios Version 3.1 and i read in the changelog that in V3.4 and 3.5 there were many TPM related changes....

Back then, a user named Paolo30 uploaded a file to which fixed this.
Unfortunatelly this file was deleted on

can someone please provide that file (or a later bios update) which fixes this?
Thanks in advance.

Answer:Need Portege R830 BIOS Update without Intel-TXT Check

Port?g? R830-10P belongs to the PT321 series so you need BIOS released for Port?g? R830 PT321

You can download such older BIOS versions from different Toshiba driver pages.
For example:

On this Toshiba Asia page I could find all BIOS for this Portege model.

How did you try to upgrade the BIOS? From the Windows or did you use the traditional procedure?

But why you want to upgrade the BIOS?
Did you have some serious problems which the BIOS upgrade can solve?

I recently picked up a Portege M200 and installed (via PXE - network install) Windows 7 on it. I would like to upgrade the BIOS as it's still at the original BIOS (1.1). I downloaded and extracted the pkg and tried to install via Windows but it says my OS isn't supported. I don't have an external CD drive or FDD - how can I update the BIOS? I tried to put it on a USB drive but there doesn't seem to be an option to boot from USB.


Answer:Portege M200 BIOS update running Windows 7?

Ok, I'm thinking I could use an SD card but I see it's not recognized by Windows 7 and when I put in a card, nothing happens...

Anyone know where I can find a driver for it? I do see there are 2 devices not recognized - one "Base System Device" and one "Unknown Device"...

And I see it doesn't recognize the video card either - just uses Standard VGA Graphics Adapter which seems to work fine...

I'm having problems with my R500, so thought I would update the BIOS.

I am directed to download

This contains the file P0058v160.exe

Starting that process leads to:

"install2 has encountered a problem and needs to close"

Do these BIOSes have to be installed incrementally? My r500 is an early one and currently running v1.00.


Answer:Re: Portege R500 - Bios update installer crashes


If you want to update the BIOS then you have to download the BIOS package and have to unzip it firstly.
Then execute the exe stored in the folder.

I?m not sure why the error message appears but please ensure that the Common Modules are installed on your system.

If the error will still persists then this could be a problem with the installed Windows OS and not with the BIOS software.

how can I update my BIOS when using Ubuntu Linux?

The reason why I'd like to update my BIOS is that on the one hand Ubuntu
writes an error message during boot-up and recommends to upgrade it and on
the other hand I'm afraid that there is maybe a temperature problem, at least the
notebook becomes slower after working for a while.

The notebook operating temperature usually is between 45-64 degrees.
The fan turns on at 62 degrees and turns off at 52 degrees.

Temperature seems to be pretty normal I would say but I think its not normal that the
notebook becomes slower when operating above 50 degrees.

I already opened it, it seems to be all right with the cooling unit, no dirt e.g...

Maybe I just persuade myself I and the performance is completely normal for a PIII with

Thank you

Answer:Portege 2010 BIOS update / operating temperature

Dear Julio

I presume you know that Linux is not supported OS and designed BIOS update is created to be performed in running Windows OS. This nice Portege is known to me and I know very well that it is not the fastest notebook and it is designed for business purposes like working with Office, e-mail communication and every other everyday activity.

Because of that answer to your latest question can be: yes you persuade yourself.

I have an old M800-106 (model PPM81E-00K00JEN). It is good condition and has been reliable, and I don't want to scrap it. Unfortunately the Windows based BIOS update from Toshiba's website froze during it's operation, and now the laptop won't restart.

The cost of sending it to an authorised service provider to repair is significantly more than the cost of replacing the laptop, and I'd be charged even if they didn't fix it. I'm not saying it's expensive - if someone has skills and does some work they should be paid for it, but it's not what I want to spend money on for this laptop.

Environmentally it'd bad to just chuck the laptop away/take to the recycling centre.

I could strip the motherboard out and send that away to have the BIOS chip replaced or reprogrammed, but that would be time consuming and risk me damaging it.

I would like to attempt to flash the BIOS chip, using the crisis Phoenix tools that are available online, but so far haven't found a *.rom or *.wph file to use.

Where can I get the BIOS file - to be honest any version that suits this laptop would do, it doesn't need to be the most recent one.

Any helpful advice gratefully received.

Please is there anyway to help me

Answer:Portege M400 - doesn't start after a BIOS update


I think in this case you must go to an ASP. I don?t see another solution for this problem because I think the ROM module must be reflashed or the completely mainboard must be replaced.

On the Toshiba website you can search for the nearest ASP: => Support & Downloads => Find an authorized service provider

And if you don?t find an ASP in your country just contact an ASP in another country. I?m sure that they will try to help you.

After updating the bios on my a100 920 to the latest 5.60 I can no longer boot from USB attached memory sticks or hard drives.

Is this a known problem? Can I revert to an older bios and if so where do I find it? If not how soon will there be a fix, or is there something I can try to fix in the mean time.

Help! It's really frustrating!

Talk about the old "if it aint broke don't fix it" biting me back.


Answer:Satellite A100-920 PS9AA: 5.60 BIOS update has broken booting from USB


Did you really boot from the USB stick???
In my knowledge this is not possible and not supported.
Only the booting from HDD, ODD, LAN or USB FDD is possible but not from USB stick or USB HDD.
But the A100 is a one of the newest notebook series and maybe the booting from USB memory was included.

Did you check the Toshiba HWSetup?? This tool supports different options and you can control the Boot Priority from this utility!
Check in the ?Boot Priority? tab if the USB memory is available and was set as first.

Regarding the BIOS downgrade; I think something like that is not possible because only the newest BIOS versions are available on the Toshiba page.
But if you want, you can contact the ASP in your country for details and maybe the technician could downgrade the BIOS to the second last version.

The latest BIOS upgrade (Ver.6.70) for my Portege Z930 12H laptop comes with the warning:

"If you are using the Windows BitLocker Drive Encryption, please temporarily suspend (or turn off) the BitLocker Drive Encryption before updating the BIOS."

Does this same warning apply to McAfee Endpoint Encryption, which is used on my laptop and which I can *not* suspend or turn off? Or can I apply the BIOS upgrade safely?


Answer:Portege Z930-12H - BIOS update and McAfee Endpoint Encryption?

As far as I know the Bitlocker isn?t related to McAfee Antivirus software and both security tools are not connected to each other. Bitlocker is a Microsoft Windows tool and McAfee is a 3rd party software preinstall on the unit.

Hi everyone,

I have got a Portege 3500 PIII-M 1.33GHz which has been infected by a virus. I have been trying to reinstall Windows Xp, but the file SYSTEM32 is now missing or has been corrupted.

I downloaded the BIOS driver and tried to install it through an external CD drive, but it did not work out.
Could you please help me at all?
I am quite concerned about the situation

Look forward to hearing from you



Answer:Portege 3500: system32 file missing - BIOS update?


I can?t believe that and virus can damage the BIOS!!!
I think you have updated the BIOS with the wrong procedure!!!
Did you check the document how to update the BIOS?

Anyway, the system32 fault has nothing to do with BIOS and I don?t understand why you started the BIOS update.

The Portege 3500 does not support an internal drive and therefore if you want to install the OS you have to use a compatible external PC-card drive.
I assume you use such drive for booting.

If some error messages appear during the installation procedure, you should firstly format the whole HDD and delete all partitions and then try again to boot from the recovery CD!

The update started correctly, but at the point "Flash new BIOS" at "Processing block 26 of 33" the update stucks!
I'm waiting since almost 2 hours, but nothing happens.
My screen freezes, I can't move the cursor, the clock shows the same time.... so nothing happens...

Is that normal?

Answer:Portege M800 - BIOS Update stucks - Windows 7 32bit


This is different not a common BIOS update process?
The BIOS update should not take a long time.

In your case is it possible that something went wrong during the flashing process and the ROM module has not been flashed properly.
I think you are in trouble and in my opinion only the ASP technician would be able to help you.

The BIOS ROM must be flashed again using an crisis procedure and this can be done only by an ASP technician.

Hi james

Don't get panicky! You BIOS is not affected by any Trojans, Malware or Virus.
Mostly such BIOS files are not known to the AntiVirus applications and therefore the anti virus software reports and notifies a virus.

Before you will start the BIOS update you should disable the virus auto protection!
