Hello,
I recently bought an IBM PC AT 5170 from eBay along with a 5153 CGA monitor. The PC only came with a VGA card, so I have been using a modern LCD with it. However, I just got a Color Graphics Adapter to use the 5153 with the PC. It works great, but when I have both the VGA and the CGA cards in the PC only the CGA card outputs a blinking cursor, and the PC never boots. It will boot with only one card at a time. How could I have both cards in the PC at once and have it still boot? I would like to be able to switch between CGA and VGA by unplugging and plugging in the cables for each. Is this possible? I could install a new BIOS if that is necessary.
Thanks!
