When MS sent out those massive updates about a month ago, the computer said one of the updates caused the driver nv4_disp.ldll to go into a continuous loop.
When turning on the computer after it started to load, the screen would go white. The only way to stop that was to pull power cord. On/off switch would not do it.
I have (I think) uninstalled the driver and attempted to reinstall the driver. The computer will only run in Safe Mode.
After that I got a message that the BIOS might be out of date. Using all the posts I could find and printing the info off the Toshiba websites, I have been unable to update my BIOS because I can not get the BIOS update screen to come up. I have tried F2 and ESC F1, and just for good measure, I've tried all the other F's.

ACPI Flash BIOS version 1.90 for Satellite Pro 6100
Why would you need to access the BIOS directly in order to flash it? The instructions are attached.

Thanks for the info.
Am I to understand that BIOS 1.90 is an update to 1.70? The dates of my 1.70 and the 1.70 listed do not match. I took that to mean there was an update to 1.70 based on instructions for my HP computer.

..there was an update to 1.70 based on instructions for my HP computer.
That doesn't matter much. Toshiba does it's own thing pretty much independently of the chip vendor. Yes, the 1.9 is an upgrade from 1.7.
When turning on the computer after it started to load, the screen would go white.
The computer will only run in Safe Mode.
Try rolling back the driver.

I failed miserably.
However, I did find that if I disable the nv4 driver, the computer will operate in normal mode.
The driver I downloaded for it, not from Toshiba web site, will not load. I have it on a flash drive along with the updated BIOS. I could not get it to load, either.
I downloaded it to C drive and then tried to put it on a disc. Since I have never burned a disc before, that didn't work, apparently.
So......any additional help you can give me for putting the BIOS on would be sorely appreciated. I'll put the nv4 off until after I get the BIOS updated.
Thanks.

Complete instructions for buring the bios update files to a self booting CD are included in the archive file/ You have to decompress the file first prior to burning it otherwise it won't work. Once you download the file you need to double click on it, uncheck the "When done unzipping open Launcher.exe" box so that it doesn't try to flash from windows. Make a note of the location it unzips the files to. Now follow these instructions to the letter to create a self booting BIOS flash CD.
--------------------------------------------------- 4) BOOT CD-ROM INSTALLATION METHOD -------------------------------------------------- - If your Toshiba PC is equipped with a bootable CD-ROM device (CD-ROM, DVD-ROM, DVD-RW, DVD-Multi, etc.), and you have access to a CD writer (burner, either installed in your Toshiba PC or in another PC), you can create a bootable BIOS installation CD-ROM using the ISO CD image, 2610v19.iso, provided in this distribution. Once you create the bootable CD-ROM, simply boot your computer from the resulting CD. To boot from CD, you can either hold down the "C" key while you turn your computer on, or you can use HWSetup to change the boot priority so the CD drive boots before the HDD. Note, if your CD burner supports it, you can use a rewritable CD (CD-RW) disc to create the bootable BIOS installation CD-ROM. Be sure to erase the rewritable disc (if it has data on it) before you proceed. Once you are finished updating your system's BIOS, you can erase and re-use the rewritable disc. IMPORTANT NOTE: Creating the bootable BIOS Installation CD requires a specific set of steps that is unique to each CD authoring application. You cannot simply copy the ISO image to a blank CD and expect to be able to boot from it. For your CD authoring/burning software, follow the instructions for creating a CD from an ISO image. Brief instructions for some CD authoring/burning software can be found in ISOCDROM.TXT, which is included in this package.
Here are some brief instructions for creating the bootable BIOS Installation CD from the provided ISO image.
Drag 'n Drop Unfortunately the Drag 'n Drop CD application bundled with
CD: many Toshiba PC models does not support creating a CD from
an image. You'll need to use a different CD burning
application.
One such application for Windows XP is Alex Feinman's free
"ISO Recorder Power Toy". This appears to be a desktop
extension for Windows XP that allows you to right-click on
the 2610v19.iso file and use Windows XP's built-in
CD writing wizard to create the bootable CD. It's a
reasonable alternative to buying a commercial software
package just to be able to burn an ISO image. Information
about the ISO Recorder Power Toy is available at
http://isorecorder.alexfeinman.com/isorecorder.htm
Note: Toshiba neither recommends nor supports this
software. Use it at your own risk.
Roxio Easy By default, Easy CD Creator 5 allows you to initiate the ISO
CD Creator: image recording process by simply double-clicking the .ISO
file in Windows Explorer. Browse to C:\2610V19
and double-click the 2610v19.iso file.
Information about Easy CD Creator is available
at http://www.roxio.com
Nero: Using the Nero Wizard, choose "CD" as the medium (default
for CD-R and CD-RW drives), and click Next. On the
following dialogs, choose Compile a new CD, Other CD formats,
Create a CD from an image file, clicking Next after each
selection, then click Finish. In the File Open dialog,
browse to C:\2610V19,
select 2610v19.iso as the image file and click Open.
From the Burn dialog, select your desired burn parameters,
and burn the CD. Information about Nero is available at
http://www.ahead.de

Your instructions are considerably more complete than the "archive" instructions.
Will try these when time permits.
Thanks, again......and wish me luck.

Actually, all of those came directly from the archive instructions. I just cut and pasted them from the readme files.

They looked more complete that what I got from the link I was given before. It gave me 5 different ways to update the BIOS. I couldn't get any to work. Obviously I didn't know how to burn a CD. I'm using a DVD+RW to make the copy and probably Nero to make it. It came with the laptop and I've never used it. Always a fun time.......
