PCI Subsystem Settings
This section is used to configure the PCI, PCI-X and PCI Express settings.
PCI ROM Priority
Selects the PCI Option ROM to launch in case Multiple Option ROMs (Legacy ROM and EFI
Compatible ROM) are present.
PCI Latency Time
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.
