#BridgeCard Problems
6 messages in this thread
Hello Out There – I Have a bridgecard in my 2000 as well as a 30Meg
RLL hard drive on the PC side. I have been doing alot of work on with the
Bridgecard due to bring home work from the office.
I decided I wanted to increase the RAM up to the full 640K. So I bought a
multi-function board that also included two RS232, one centronic one game
port,and a clock/calendar. Everything works fine Execpt, I CANNOT get the
machine to recognize COMM2:. COMM1: is fine, in fact I hooked up a mouse and
ran PCPAINT in the CGA mode, PERFECT!!!!!
Has anyone out there had this problem?????????
Is there some reason that COMM2: is not found?????? I thought I would check
here first before I start digging in with DEBUG and a memory map.
Thanx Peter Ganczarski
Peter,
Please forgive if this seems a bit trivial, but, I would double and triple
check the jumpers and switch settings on the MFB. There are so many that it is
_very_ easy to miss one. I have been fighting a MFB in an IBM-AT recently and
it is not the first time or machine that I have had trouble on. One thing that
also bears checking is the MFB's battery. In a couple of machines at work pure
havoc was wreaked due to clock battery failure that seemed to be other
problems. Remember that the board (or battery) may have been around a long time
even though you may have just purchased the board.

Thanx – I gave that seriuos checks and all is O.K. I've heard that there is a
conflict between the COMM2: address and special ram for intra buss
communication.

Peter,
On our MS-DOS machines at work, we have to add the line:
driver=ex_rs232.sys
to get COM2 to work. The machine comes with a built in serial port,
but COM2 is a plugged in serial card….you may have to do the same thing.

Don – Thanx I'll look into it.

Peter,
Whoops…that wasn't clear when I re-read it. You may have to add that
line to your config.sys file…not add a serial card…you already have that.
