I had the same problem, although with a different board that only had 1 meg, but the same "missing 512K" problem came up. How I fixed it was simple, but counterintuitive. I don't know if the Above board has settings to indicate the base address. If so, set it so that it starts at the 1.5MB mark. Yes, that's 1.5 and not 1.0. The manuals I had said something about that, and as silly as it sounds, it works. Don't forget to set the computer to 512K mode and use setup. If you don't setup, you'll be battling parity errors until you do. :-) -- Roger Murray UUCP: ...!{ihnp4,randvax,sdcrdcf,ucbvax}!ucla-cs!cepu!ucla-an!remsit!rem ARPA: cepu!ucla-an!remsit!rem@CS.UCLA.EDU
