D.A.R.R.Y.L. schrijft dat er op het forum van SysOpt.com een interresante post is te vinden waarin wordt uitgelegd hoe je een beta BIOS op een nVidia kaart kunt gebruiken / uitproberen zonder daarvoor eerst het BIOS te flashen. Op die manier hoef je niet bang te zijn dat je kaart onbruikbaar wordt door een eventueel fout BIOS, omdat het oude BIOS na een reboot weer actief wordt 
:
I'm sure all the nVidia users here have either used or heard of nVidia's leaked refrence drivers. They usually are updated more often, have better stability and performance, and newer options than the vendor drivers. What if I told you the same thing was true for reference BIOS's.
You might wander, "what if I flash my card with a reference BIOS, and it fails on bootup?" There's a simple answer, it's called VGABIOS. It is a leaked utility from nVidia that will allow you to run the latest BIOS without flashing your own. It is a ms-dos TSR program that loads the BIOS from your autoexec.bat file. It then sets the BIOS commands to be directed to it and the BIOS file it loads. It's also extremely easy to use, and low on resources if you use the ms-dos lh (loadhigh) command. A sample line might be:
lh c:\vgabios -fULTRABT.ROM
[...] The only reason I mention this is that stability for my TNT-2 has been seriously affected by using the latest BIOS. I haven't suffered the first crash, and beleive me, I've tried to. I haven't seen if my chip will o/c any higher, since it usually tops out at 160mhz with extreme cooling. My next plan is to actually flash my card with this BIOS, but I want to try it out awhile longer before attempting that. I will also warn people, that flashing a card with an non-vendor specific BIOS can limit its functionality, and possible destroy the hardware. I would recommend using VGAFLASH, as if it screws up, a fresh reboot will resolve your problems. Make sure everything works before putting this file on autoexec.bat . But even then, ig you have problaems, a quuick reboot to safe mode DOS, and deletion of the command line from the autoexec.bat will fix everything. It gets a lot more complecated when dealing directly with your cards EPROM chip.
