View Full Version : Correct way to update bios of 8800GT in Vista

I have an XFX 8800GT XXX-OC. My OS is Vista Home Premium 64. I put in a request at XFX for a new bios with a faster stock fan speed. I received the bios and installer with no instructions. When I try to install, a black screen opens, a few fast lines are printed with some error and the black screen closes so I have no time to read what is there.

Has anyone succesfully installed an 8800GT bios in Vista 64? I don't want to experiment for fear of messing up the video card. I put in an updated request for help but have not been answered in several days.

Best not do it from windows:
Use a Dos boot floppy/CD (get nero 8 to burn one off)
Copy your bios file to the root direct, i.e. C:
Now download nvflash (latest version is 5.57 (http://www.mvktech.net/component/option,com_remository/Itemid,26/func,selectfolder/cat,42/page,2/)), copy the two files (one is nvfalsh.exe and another one, can't remember what it is called!)
First make sure you backup your bios (follow the first two guides here (http://www.mvktech.net/content/category/4/67/37/))
Boot into dos via the floppy or CD:
then when in command prompt type:
c:\ (<--this will set the directory to the C drive)
nvflash -5 -6 yourbiosname.rom

where "yourbiosname" is the name of the bios you have got.
Hope this helps!

I used NiBiTor 3.4a and Winflash 5.33 and flashed both my cards within Vista 64 with no problems.

Thanks for all the help. XFX sent me an email that was no help. They just said double click the installer file..."duh!"

The answer was that I had to run the installer as administrator. I thought I tried that before. I did re-copy the files from the original email before trying again.

Make a bootable floppy, download nvFlash v5.57 and copy the two files named > nvflash & cwsdpmi to the bootable floppy, copy your bios over to that floppy, re-boot your system, press F8 & chooses to boot from your floppy, then type nvflash -5 -6 newbios.rom (type whatever the bios is called & then .rom) .. then follow the inscreen instructions.

easy peasy.

I can't find 5.33 anymore either but here is 5.1 though I've never tried this one:

Runs from within Vista64.
