[net.micro.pc] Expansion Chassis

We recently took delivery of a pair of expansion cabinets for the
IBM-PC.  Installation was easy 10 Megabytes of disk is wonderful and
lots of slots is even better.  For all of Dos 2.0's many faults it is
a great improvement over stretching DOS 1.1 to a large disk.

I was surprised to find that the diagnostics were able to survey the
system and find all of my devices.  It was also able to tell whether
the device was in the expansion cabinet or in the main chassis.

Does anybody know how the PC can tell where a device is?  We have no
equivalent of the blue technical reference manual for the expansion
chassis.  Can the Tecmar or other expansion units duplicate this
feature?
