This is a simple guide on how to mod your Nvidia video card's bios and flashing it, and also how to backup/restore your original bios, just in case it doesn't work out.
This process is fairly simple, and in my opinion foolproof, but just in case you do screw up, you can always flash it back using a PCI card to boot computer.
Okay first of all you'll need the following things,
1. Floppy drive
2. Floppy disk
3. Download the program NiBiTor
4. Download the NVflash utility
5. Balls
First to back up your original bios:
-Create a bootable floppy disk, then copy the NVflash files onto the floppy.
-Set computer to boot from floppy in bios
-after the floppy disk has loaded, type "a:nvflash -b backup.rom" without quotes, then press enter. this will save your current bios on the floppy as backup.rom
There you've backed up your current bios, in case the new bios doesn't work out just flash back to this.
Now reset computer and go back into Windows, open the backup.rom file on your floppy disk using NiBiTor, modify it any way you like, change the voltages a bit, tweak the memory timings a little(BE SURE TO KNOW WHAT YOU ARE DOING!), increase/decrease clock speeds. Save the file as newbios.rom
Here's how to flash your card with the new bios:
-Boot from the floppy with NVflash and the newbios.rom
-After floppy's loaded type "a:nvflash -p -u -f newbios.rom" without quotes, and press enter.
-Reset computer, and go into windows, it shouldn't have problem with driver, since you only modfied your own bios. However if you've flashed to a different brand or different chipset's bios, you will need to reinstall your drivers.
You're done, your card now has the new modified bios
Now if your card behaves strangely, such as crashing in 3d, or artifacts, or crashes in coolbits, that means your card can't handle the new settings, and you'll need to restore to the original bios.
Here's how to flash back to original bios.
-Boot from nvflash with backup.rom floppy
-type "a:nvflash -p -u -f backup.rom" without quotes and press enter.
Now if you screwed up majorly, your card wouldn't even boot anymore, you could blind flash the card back to the original bios, or you could use a PCI video card to boot the computer and monitor, then you can flash the bios on your primary card back to the original.
I think i covered everything, if i remember anything else i'll update this. This is a very simple process, and can't go wrong, so if you got all the stuff i said you'd need, then give it a try. If your card sucks and doesn't work out, hey just flash it back, you got nothing to lose.
Okay, have to mention this in the end, if you're a dumb@ss and screw up your card, I am in no way responsible, you do this at your own risk.
Update: I will get an update soon on how to flash PCI Express cards and SLi setups.
