Problem with nvflash

I have no name gf2 MX200 and bios for it. when i try to flash it nvflash says unsupported eeprom. Does this mean that i canot flash my card???

I got the same problem with my GF 256 DDR Absolute MM!?<br>
"ID devcode (DA,C8): supported EEPROM not found"<br>
"ERROR: supported EEPROM not found"

i have a problem with nvflash too (v4.13) -- i have a geforce2 mx400 (creative) and i get the following error when i try any operation:<br>
<br>
ERROR: PCI BIOS not present<br>
<br>
my card isn't even PCI!! what's happening?<br>
<br>
can anyone help?<br>
<br>
additional: for some reason, my creative card has a winfast BIOS in it, which i find weird.

Finaly I manage to flash my GF1 DDR Absolute MM!<br>

When I try to enable extra driver options in Windows 2000, within the OpenGL by enabling this key: <i>[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIACorporation\Glob al\<br>
NVTweak\OemConfigurations]"ControlsOverride"=dword:00000001 </i> <br>
in the registry and copy´d the nvwsapps.cfg from Detonator folder to system Windows folder, the options are still "grayed out"? <br>

Guyz, never try to flash BIOS under any versions of Windows. Boot to clear DOS environment before do it. Some NONAME card have EPROM, it can't be flashed <IMG SRC="smileys/frown.gif"> READ/ONLY ROM. Some ROM can be flashed using other utils, like wwflash.exe
