PCI ROM Priority
Select this option to set the ROM priority (Legacy or EFI Compatible)
PCI Latency Timer
Select this option to set the PCI bus clock. Devices that operate in bus-
master mode require a timer to limit the use of the PCI bus. This allows the
use of the PCI bus by various devices. Setting a latency timer too low
interrupts transfers unnecessarily, while setting a timer too high may cause a
buffer overflow (devices requiring frequent bus access).
