Automatically assign an IRQ for the VGA card installed.
[Disabled]:
The IRQ that was previously occupied by the VGA card will be available for new
device.
PCI Latency Timer(CLK)
This item controls how long each PCI device can hold the bus before another takes over. When
set to higher values, every PCI device can conduct transactions for a longer time and thus
improve the effective PCI bandwidth. For better PCI performance, you should set the item to
higher values.
Maximum Payload Size
This item sets the maximum TLP payload size for the PCI Express devices.
