[comp.sys.apollo] Problem with DPCI Token Ring in XT PCs

jimr@extro.ucc.su.oz (Jim Richardson [ext 2232]) (08/30/89)

We have been trying to use a token ring board in a variety of XT PC clones,
without success.  The RINGDIAG diagnostic in the Domain/Personal Computer
Interconnect (DPCI) package always gives the message "No ring board found".
We have tried both the alternatives for the jumper settings on the board,
and are running DOS 3.10 or 3.2. 

The board works fine on our ATs (provided we slow the clock speed down; we also
did better when we found out that DPCI on the PC turns passwords to upper-case,
so your Apollo password cannot contain lower-case letters :-( ). 

The DPCI manual says that the token ring board will work in either ATs or XTs. 

Has anyone anywhere succeeded in using a token ring board and DPCI in an XT?
If so, please pass on any useful tricks or hints. 

Thanks in advance.

We have a ringnet board in an an XT clone here. It's been a while
since we put it in, but it's working fine. If I remember correctly,
we had a couple of porblems during the installation. The first was
that the hard disk controller on the XT uses the primary address
for the ringnet controller. The second was that our multi-function
board (time-of-day clock, memory, and monochrome diskplay) also 
interferred with the ringnet board. It turned out that we had to disable
the time-of-day clock in order to get the ringnet board to work.
