Erm, yes it is, all PCI slots share the same data and address lines,
it's a bus remember.
The IRQ's are usually connected in a round robin way, IRQ A is IRQ B on
the second slot and IRQ C on the third etc. A PCI card normally takes up
the first IRQ but can take second, third or fourth. All PCI cards should
be able to share IRQ's but some are more well behaved than others...
There are lots of proprietary motherboards around which have only one
PCI slot with a riser to create 2, 3 or 4 horizontal PCI slots. (Low
profile Compaqs, HPs etc.)
