I have no idea what the ROMs are, but I suppose they're not the right ones. I say that because the card will not work at all with OS3.1. The CPU is recognized using OS2, but the memory is not recognized. So do I likely have a defective card? If the memory itself were defective, would I expect none of it to be recognized (or would I more likely expect the card not to work at all)? Thanks for your help.
