I am writing this message because Commodore Technical Support has been unable to pinpoint my problem. I am working with an A2000HD with a version 6.0 mother board, 1 MB CHIP RAM, A 2090a hard drive controller, rodime 40meg drive, version 2.0 of the Janus Software with a 2286 Bridgecard. When I had the hard drive divided into a BOOT: partition and 2 FFS partitions of 20 meg I had trouble running PC-Colour, PC-Mono worked fine. When the computer was booted from the hard drive and PC-Colour was run the screen went black with a grey undulating field of raster lines overtop of it. This is using a Commodore standard 1084 monitor of course. When I boot from the floppy drive and run pc-colour it works fine. If I boot from floppy, mount FH0: and run pc-colour it doesn't work at all. In both circumstances PC-Mono works fine. It seems that when the hard drive partitions are mounted then the problem occurs. When the hard drive was reformatted for standard file system the same situation persisted. It should be noted that there is no CHIP RAM in the system. Due to this fact PC-Install as provided with the 2286 would not run, although, mini-install would run. when the system was fooled into believing that there was some CHIP RAM PC-Install would run but PC-Colour still would not run properly. The only suggestion I could get out of Commodore was to have the Mother Board upgraded to 6.2 or whatever the latest version is. Unfortunately they could not understand why I was having the problem in the first place because according to them "Identical configurations have always worked in the past". They also could not explain why upgrading the mother board would eliminate my problems. Thanks, Your suggestions and contributions the the solution of this problem will help me quite a bit.
