    What improvement in performance do you get with the 5950U BIOS? I keep
    thinking of trying this with my Aopen 5900 but I am too chicken to do it!

    Well you go from 5900XT performance, to 5950 Ultra performance :)
    I've not bothered to do any benchmarking, but the 5900XT clockspeeds are
    400/750, and the 5950U clockspeeds are 475/950 - a sizeable jump !
    You have nothing to lose. If it doesn't work, then just flash your old BIOS
    Use "WFFLASH.EXE S" to save your existing BIOS (it saves as SAVEOLD.ROM -
    rename the file straight away, and put it somewhere safe - it gets
    overwritten each time you flash !)

    Then "WFFLASH.EXE NM BIOS.ROM" to flash the new BIOS. I must have flashed
    mine 30 times when I was testing them all out, and every single flash went
    just fine.

    Worst case scenario is that your card won't boot after flashing. In which
    case, just slap a PCI graphics card in aswell, boot to it, and flash your
    old BIOS back from there.

    OK thanks for the info. P.S. I don't have an XT - I have the original 5900
    which is clocked at 400/850 and using the Nvidia auto-overclock feature I
    get 450/970 stable so still not sure I will see much difference...
    BTW even with this overclock I see no difference in, say, games like Far
    Cry - the FPS stays exactly the same. But I think using the Nvidia
    auto-overclock it alters the speed based on temp etc? Not sure though.

    Another idea I've read, for those without PCI video, is to create a boot
    floppy that automatically runs the flash program and contains the original
    BIOS, in case it goes pear-shaped!

    You will be able to go a lot higher than that with the 5950U BIOS. It raises
    the cards core voltage by 0.1v and backs off the memory-timings very
    slightly - you'll probably be able to get well over 520/1040 with your card
    It also speeds up the fan slightly, so your actual card temp usually drops !
    I don't have any concrete information on the Auto Overclock I'm afraid.

    Not sure if you'll be able to actually boot the system without a PCI GFX
    card inplace, if your AGP card is pooped ?
    Any old PCI card will do though - just pick one up from eBay for £1 :)

    Go on - give yours a go ! I'm very happy with mine :)

    Flashing the nvidia BIOS, you do not need to see anything to be able to
    flash it ROM as long as the batch file on the floppy is correct.
