BIOS Setup
Assign IRQ For USB
When Enabled, the system automatically assigns an IRQ for the USB
device connected to your system. However, if you are not using USB
devices and an ISA slot requires an IRQ, set this field to Disabled.
The IRQ previously occupied by the USB device will be available for
the ISA slot.
PCI Latency Timer (Per 8CLK)
This feature is used to select the length of time each PCI device will
control the bus before another takes over. The larger the value, the
longer the PCI device can retain control of the bus. Since each ac-
cess to the bus comes with an initial delay before any transaction
can be made, low values for the PCI Latency Timer will reduce the
effectiveness of the PCI bandwidth while higher values will improve it.
INT Pin 1 Assignment to INT Pin 8 Assignment
By default, a device is automatically assigned to each INT. You can
also manually assign an INT for each device.
Maximum Payload Size
This field is used to select the maximum TLP payload size of the PCI
Express devices. The unit is byte.
