GeForce 6800 GS and BIOS flashing gave scrambled image? - 2008/06/06 11:42 Hi all, I have a Palit GeForce 6800 GS 256MB version being with GDDR3 memory and I did a flash with the BIOS from the site. It did flash with no problem, though when I restarted the image was scrambled. I do not manage to do a blind flash and my question is, does it work to put a PCI card and to flash this one?

Re:GeForce 6800 GS and BIOS flashing gave scrambled image? - 2008/06/06 12:52 Yeah well BIOS flashing is not always going to work if you don't check upfront if there are no rel significant changes related to the clock speeds and memory timings. And most likely your GeForce 6800 GS is using different memory chips and which is now giving these so called artifacts, which are very bad for the graphics card. So you do have a backup of the original BIOS that came with your Palit card? Can you share it with us? What you will have to do is to create a bootable Ms DOS media, which can be either a floppy or a USB memory stick and put nvFlash v5.13 on it and your original BIOS.

Then create an "autoexec.bat" file on it and write just one line in it as listed below and make sure of course that your original BIOS backup is with the same name as in the command. Then reboot from this bootable media and your card should be flashed automatically and rebooting once done. After that your card should have again the original BIOS and work as before. And yes you can use as well a PCI graphics card so you can view on the screen.

nvFlash v5.xx Commands...
"nvflash -4 -5 -6 -A -y oldbios.rom"

Re:GeForce 6800 GS and BIOS flashing gave scrambled image? - 2008/06/06 19:34 This is the original BIOS of the board. hat do you mean by the automatically, you don't have to write no command at all? You just reboot, and the "autoexec.bat" does it all?

Euh yes, you make sure you have nvFlash and your original BIOS on the bootable Ms DOS media and the "autoexec.bat" with that command in it, and when you reboot it will execute that file automatically and execute that command. Now one thing I have removed your BIOS you attached as the size was only 0kb, which means if that is the BIOS you used that you have a corrupted file. A backup should be around 60-65kb, and yours wasn't, at least not the one you attached on our forums.
