- I have a 16 bit SVGA card Im trying to upgrade to 512K so I can use the
- 800x600x256 mode. The card currently has 4 44C256 drams onboard. The IC's
- are of the 20 pin DIP variety. Are these 256x4 chips? I also have some
- Intel DRAMS (also 20 pin dips) which, when installed in an AT, give me 1meg
- memory from 8 IC's. Are these 1024x4 chips? I want to install 4 of the Intel
- DRAMS to get my 512K. I tried it and the board worked, but nothing recognizes
- the (apparent) added memory. There are dip switches and a jumper I have not
- tried fooling with yet.
-
- The Intel DRAMS are marked P21014 and I can find no references to theses IC's
- anywhere. Is my logic correct, and I just need to fool with these switches, or
- have I completely made a fool of myself?
