When I used a WD8003 on a Xenix system, the kernel I was running saw the
ethernet board at I/O address 0x280, and thought it was a TANDON multiport
board! From /usr/adm/messages:
%fpu - 35 - type=80387
%floppy 0x3F2-0x3F7 06 2 unit=0 type=96ds15
%floppy - - - unit=1 type=135ds18
%serial 0x3F8-0x3FF 04 - unit=0 type=Standard nports=1
%serial 0x280-0x287 03 - unit=1 type=TANDON nports=4
%parallel 0x3BC-0x3BE 07 - unit=1
There went /dev/tty2* ("COM2"). If the board comes up defaulting to that
address, your Xenix may also see it as a TANDON board. Check /usr/adm/messages
for something like the above.
To solve it, what I did was to go into /usr/sys/io, and edit sioconf.c so
that any boards which had an address in that range, and deleted the line so
the kernel wouldn't auto configure that board.
I can't help you with the DOS problem, sorry.
