connect the VGA device, can release the IRQ for other device.

bus master can retain the ownership of the bus.

These settings allow the user to specify what IRQ will be assigned to PCI devices in
the chosen slot. The defaults are Auto.

IMPORTANT!

or that the cards dont need IRQ assignments. Conflicts will arise between the two
PCI groups that will make the system unstable or cards inoperable.
