About a year and a half ago I picked up an old IBM PC 340 at a recycling center. It was a mess and was in pieces, but I cleaned it up and put it back together and it has been working well. I've also upgraded and added some things to it - added more memory (80 MB now), a new CPU (P166), a CF adapter, and now I've been trying to upgrade the video.
I found an ATI Rage 128 Pro and installed it, but the machine will not post with that card installed. It's the PCI based version for PC. There's a jumper on the motherboard to enable or disable on board VGA, but that doesn't seem to have any affect on this issue. I've also put this card in an XP machine - it booted into Windows and identified itself as the AGP variant (it isn't).
I've scoured IBM documentation and other forums and have come up empty handed. Is there something simple I am missing?
