Yeap.

If you're short of IRQ's you can also try to set things up so that the
shared IRQ's are only being utilized by devices which are never used at
the same time.

E. G.

You NORMALLY will not use the Network card and the TV tuner at the same
time, unless you are capturing to a network, device. (This is just an
example.)

Or as another example, you may have a SCSI scanner. You probably will
not be scanning and watching TV at the same time, so set the tuner and
scanner to share IRQs.

Moving the card from one slot to another changes which device it shares
an IRQ with.

If you have 5 slots and AGP...

54321A

A (for AGP) and 1 normally share an IRQ with slot 5.
4 & 2 normally share and 3 has it's own.

The exact sharing sequence is hardwired by the manufacturer, so it will
vary according to the motherboard you have.

In turn this confuses many people who erroneously assert that they can
modify ALL IRQ's in the BIOS. You actually can't. You can change WHICH
IRQ a shared set may get, but the sharing remains never the less.
