I invested in a Matrox G250 AGP (factory OC'd G200) and a VRAM upgrade for it (yeah I've heard it clocks it back down, dunno if I'd end up using it or not), for use in my 300Mhz Pentium box (and yeah, I mean Pentium, not P2, etc.). I set it up, working fine, but when I install drivers for the card and reboot, the screen image is a series of lines and garbled crap, except the cursor, which appears slightly garbled but drawn correctly and controllable, with a box around it for some reason. I see patterns in the garbledness that change here and there, which I think corresponds to screen changes. Not real sure what's going on here or why the drivers don't work. Ideas?
My first thought would be corruption in the on-board VRAM for the card, above the space used for 640x480 (thus it works fine in BIOS, setup, and safe mode, as well as pre-driver install) - however, even if you boot to safe mode, force the resolution to 16-bit 640x480, and reboot into normal mode, it won't work, which it would if this were the case..
I tried installing the VRAM chip out of desperation, and it did not help either - it did cause more random corrupted lines to be displayed, though. 😜 On a side note, the card still reported 8MB VRAM, so it wasn't detected, but with the drivers malfunctioning I'm not sure if it even should be? xD
