I should have also added:

Even though there are no ISA expansion slots on your machine, you
still have an ISA bus living inside (unless it is a legacy free
machine we keep hearing about, which I didn't think was on the
market).  The PC-99 standard (not to be confused with the Japanese
PC-98 machines) states that you cannot have a ISA expansion slot, but
a later clarification to the standard states clearly that you can
still have ISA devices built into the mother board.

In other words, No ISA slots doesn't necessarily mean that the machine 
doesn't have an ISA bus.
