Hi all, I have installed this XT-CF card in my PS/2 Model 25SX but it won't bring up the option ROM of the card.
I tested and used the card in an AST 486 and it works perfectly in that computer. I installed MS-DOS 6.22 on a 32 MB CF card.
The PS/2 however shows error 161 and 163 (invalid CMOS settings), and when I press F1, it tries to boot from floppy disk and then goes straight to BASIC. No option ROM of the add-on card is shown.
The problem is that the FDD is bad and I am trying to avoid having to repair it. I did replace the CMOS battery but never set the BIOS settings because I can't boot from a diagnostics disk.
Is there anything I'm not aware of with these computers? Should I use different jumper settings on the motherboard or card?
