i am having the same problem. Every one has told me similar things as the other guys, but this is NOT the case. See, the video card has a BIOS just like the system BIOS. Proly what happened is that you got the wrng drivers and after install, they corrupted the video Bios. The video Bios runs between the initiall turn on and before th eOS, this is the part where you are having problems, (because so am I ) I have the EXACT same problem on the EXACT same display card. The thing is I have searched everywhere (thats how I got here) to find dos based adapters for this card so I can run them after I boot into Dos. BUT I CANT .
You (and I) need Dos based drivers to run to flash the old video bios (if Possible, which I dont know if it is)
Can anyone help instead of just speculate ???? (sorry but this is frustrating when everyone tells you the same thing you KNOW is wrong )
TO THE REST READING THIS :
The Bios (system bios) loads fine, if you hit f12 the bios loads and uses the whole screen, but between system bios and OS load, the screen is garbled where the display is crunched in half the screen and the lines overlap each other.
Since he was in the middle of install, (I assume) there is no OS anymore, he needs video drivers inb DOS to rattify this, HELP HELP HELP
