The problem may not be parity.
Many 486 motherboards with 4 30 pin slots and 2 72 pin slots will not run a
full RAM config. Some will, and you need to set a jumper for the board.
Let me know if you need help finding a manual. If you contact me, first
boot up the machine (if it has an award or AMI BIOS) and write down the
complete number that appears on the lower right of the screen. As soon as
the number appears, press the pause key so you can write it down.
Other 486 boards with this slot configuration will run with all 4 30 pin
slots full and one of the two 72 pin slots filled, but not with both 72 pin
slots and the 30 pin slots filled.
Also, if you are using EDO 72 pin RAM, a few 486 boards support it, but most
don't.
I've never seen a 486 motherboard that supported either a 3 volt CPU or 72
pin SIMMs that required parity RAM. In fact, I can't recall ever seeing a
486 socket 3 board that did. And I've seen many 486 boards come and go....
Try running it with 72 pin RAM only and see what it does...
