PCI ROM Priority
In case multiple option ROMs (Legacy and EFI Compatible) exist, select the
PCI option ROM to launch.
PCI Latency Timer
This feature is used to select the length of time each PCI device will con-
trol 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.
