BIOS Setup
Assign IRQ for VGA
When Enabled, the system automatically assigns an IRQ for the VGA
card installed. Your VGA card will need an IRQ only when using the
video capture function of the card. If you are not using this function
and a new device requires an IRQ, you can set this field to Disabled.
The IRQ (previously occupied by the VGA card) will be available for
your new device.
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 (CLK)
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
access 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.
