plz help with gforce4 agp card

[cpp]

ok, i got a gforce4 mx 440 agp card and installed it. now in the windows control panel it seems to be on pci port 1(?). games run hardly faster than with the voodoo3 pci card i had installed before. also they crash where they never did before and the computer hangs.
i tried to flash my bios, but it seems to be write protected. how can i remove the write protection?

[soupy]

Driver issue; don't mess with the BIOS.

[cpp]

thanks
