I am in the process of attaching a number of 386sx machines (made by Tulip of
the Netherlenads) to a Token Ring Network using 3Com software.
These machines have 1Mb on the motherboard, making 384 kb available as extended
memory. In order to have as much space for DOS applications free as possible,
I use the Qemm drivers to load most of the network software in so called High
Memory.
Unfortunately, Qemm does not recognize the correct locations of the ROM and
RAM of the Token Ring Adapter (IBM Token Ring Network PC Adapter II, to be
precise), so I have to exclude these areas manually.
The default configuration si as follows:
ROM CC00-CDFF 8kb
RAM D800-DBFF 16kb
If I exclude the whole area from CC00 through DBFF, everything works fine.
However, if I exlude the two areas separately, the network software won't
run properly (for those of you who know 3Com, the program RUNMINDS hangs)
and freezes up the machine.
Another option I have tried is to move the RAM area of the TRA to another
location, say C800, so as to be adjacent to the ROM area. Alas, excluding
this area on the call to Qemm also hangs the machine.
I think that there may be three problems at work:
1. Qemm does not function properly when specifying more than one
area to be excluded (I find this somewhat hard to believe);
2. The TOKIBM driver cannot find the Token Ring Adapter at another
location than the default one (but it does work when I don't use
Qemm, so that in some cases it can find other areas);
3. The Token Ring Adapter does not use the areas that is says it uses,
when I start up the machine without using Qemm, I am not able to
locate any ROM at CC00, however there is some stuff near CDFF and
just above it, at CE00 and beyond.
Can anybody tell me the following:
1. What are the parameters for the TOKIBM driver when used with the
TRA as described (all my manuals say that the info is in another
manual);
2. Does the TRA really use the addresses as advertised, and if so,
what is the stuff doing at CE00;
3. Does Qemm have problems with excluding areas.
You can mail me, and I will make a resume for the net.
