This may be a dumb question but I've never seen it asked or answered so here goes..... Why is 6-meg of fast memory the ideal configuration for a system with a bridgeboard? Does it have to do address contention on the Zorro buss? This is of some concern because I have an XT bridgecard and a Microbotics 8-up with 6-meg along with 1-meg of chip ram on the motherboard. What happens if I add another 2-meg to the 8-up card? This may be a moot point as my Mega-Midget-Racer is due any day now and any new memory added in the near future will be 32-bit memory :-) Thanks.... dave Another dumb question brought to you curtesy of (insert favorite flamee here)

Normally a RAM card is configured before a bridgeboard, so after configuring this RAM card, all available address space is already given there, and nothing remains for the bridgeboard, which also needs some space (was it 512 KB?). So your bridgeboard wouldn't be able to autoconfig, and thus remain sleeping, plainly not useable, sad... -- Best regards, Dr. Peter Kittel // E-Mail to \\ Only my personal opinions...
