Yes, most earnestly. We did not have the chance to add in some excellent contributions of new code for high speed operation. Note that for high speed serial, you'll absolutely need a board with FIFO, as the 16450 won't cut it. There are also some excellent boards in the amateur radio world that use DMA and do sync/async at quite interesting rates, not to mention ISDN boards that are also quite interesting. > I tried to bring up 0.1 and 0.0 on my personal computer.

No BIOS problem. 386BSD *currently* uses little of the BIOS (and even in future versions, Phoenix BIOS is just perfect). I need more information about the kind of floppy disk (this had better be a high density at least), amount of memory (base memory of 640K I hope), and other details. How long does it read the disk for (10 seconds -- bootstrap failure -> bad floppy, >60 seconds -- reading system -> should get error message). Please send mail on this one, don't repost. Bill.
