Hello netters,
I am trying to install a WD8003E net card on a Wyse286 AT to run
Stanford University's PC/IP version 3.0. So far it hasn't been a
complete success.
The system has the following:
a) Wyse pc286 with 640 KB ram, pheonix bios 2.75G, 10MHz clock
b) Vega VGA card (version 1.47): switch - NFFFNF (123456, N=on, F=off)
c) Microsoft bus mouse: Primary Inport, Int 2
d) Harddisk controller card (40 MB)
I've set up the net card as follows:
a) I/O = 300h
b) Wait-state set as PC AT (8-16MHz) - W1's pin 2 open
c) IRQ 3
d) Thin Ethernet (W4 closed)
e) W3 set to thin ethernet
f) loaded net_wd.exe in config.sys after customizing it
After booting up, running tcpip.exe hangs the machine (it's well hung,
i.e. it's not warm-bootable). I know the card works (tested on our
other machines, not all true-blue ATs, but works on all of them).
I set the RAM buffer address to D000, D400, D800 and DC00 and none
worked.
When I took out the Vega card, set the W3 to all open (ie standard
ethernet), and used a monochrome card, SU-PC/IP worked (ie tcpip.exe
ran). I used an EGA card from an IBM AT and that configuration
worked also. All the RAM buffer addresses above worked.
I have successfully used an Ungermann Bass UBNet card with the
Vega card. So I know that net cards can be used on the pc.
Setting the W3 closed and using either the monochrome or EGA card,
left the machine well hung when tcpip.exe was run.
There obviously is a conflict between the Vega card and WD8003E
though I just can't figure what it is. I've tried all reasonable
jumper settings on both boards to no avail. I'm currently assuming
that there is no problem with the Wyse motherboard. Maybe I'm wrong
here. I don't have another Wyse machine to test on.
I need to use the Vega VGA card and for where the pc is going to be
used, there is only a thin ethernet connection. I can't use the
other machines at this location because of logistics.
Has anyone encountered this situation, or am I the only one?
Thanks.

I ran into the same problem with a Dell system which also has a Vega VGA card. The VGA card BIOS seems to take up D000 - DFFF. To get the WD8003 card to work you must use E000 (or higher) for the RAM buffer. Drew

Somthing about startup routines getting confused and thinking thay are talking to Serial IO boards. Maybe this helps ? Dave Malik MicroUnix Australia (Perth, WA office) +619 474 1184
