Thank you. I haven't read everything yet but this looks
like an excellent reference on IRQ's, etc.
The card plugs in to an ISA 16-bit connector. The entire
edge connector fills the ISA slot. If you look in to the slot,
there is a break which, I seem to recall, will allow one to
insert a 8-bit card or the longer 16-bit card. Anyway, I see what
you are saying about it registering to the 8-bit IRQ's. as in
anything below IRQ 8. This may be the problem and setting it in
the BIOS may translate IRQ 5 to Irq 8 or above which would remove
the contention. This really makes a lot of sense. The Module for
the first card to register probably determines that something is
already on IRQ 5 in this case and properly does not attempt to
attach anything else to it.
If there is a reasonable solution to this issue, after
reading the links you posted, I will post it to the list and
maybe save somebody else some head-banging.
