[comp.sys.ibm.pc.hardware] Token Ring Blues

et10+@andrew.cmu.edu (Edmund E. Tsai) (10/11/90)

I was just wondering if it's allright to plug my 8-bit token Ring 
into a sixteen bit slot on my 386sx using an Intel chipset and 
AMI bios.

The reason I ask is that I am getting an error message whenever
I run the diagnostic.  Since the card uses an interrupt, I am 
thinking that it would cause problems.

I have seen the discussions on using a 8 bit hard drive controller in
an 16 bit slot but there were a few varied opinions.

Thanks 
Ed

   Unless there's something screwy about the motherboard and/or BIOS, this
should not cause a problem.  I've been installing 8-bit TR boards in machines
ranging from an old XT clone through 386 machines for over a year and haven't
had any such problems.

   If you can tell us the error message, we may be able to offer better
assistance to you.  You can check the interrupt the card uses and see
if it conflicts with anything else in your system; however, this is not
often a problem except in machines with lots of expansion cards in them.

   I'd also check any memory requirements the board has.  Some TR boards
don't need any memory space, but many do.  IBM boards, for example, have
RAM and ROM to fit into the address space, and I've seen many machines
in which this has conflicted with something else, typically expanded
(EMS) memory.  If you have EMS in your machine, make sure it isn't con-
flicting with your TR board.

   If you still can't solve the problem, try posting again with details of
your hardware configuration and the error message.
