I have the board installed in a Micronics 386-25 board with 8MB DRAM, WD1006-SE2, PRIAM V185 hard drive, Archive 60MB tape drive, and Computone Intelliport AT6 serial board. I have this system setup running MSDOS 3.20 and Windows 3.0 without any problems at 800x600x256 (this is a really nice board). I have a customer that has the STB 640 VGA which is only 16 colors in the higher resolution modes. The board did not work in the 20mHz 386 C&T board that he had. The board would not even work with a C&T VGA card. There was a bus addressing problem. You could have a problem with the mother board or you could have a problem with the VGA card. When I am not running MSDOS, I am running Interactive 386/ix UNIX Release 3.2, Version 2.2 with Xwindows at 800x600x256. I could run 1024x768x256 but my monitor can't handle the stress of the higher frequecy that long. Let us know what you find. Charles -- C.
