Note the PnP for ISA is a nightmare...a real  joke if you have shared
memory cards because of the limited space available. If you try
to set a PCI card with 64kb of ram to "below 1 meg" most of the
time the machine will hang or fail if you have another shared card
also, because there isnt enough contiguous space for both of them.
The bios' just aren't smart enough to solve these problems, and once
a card is configured they can "reallocate" the space if something else
needs to be fit in. They just fail.
