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.

VGA Palette Snoop
Enables or disables the VGA palette registers snooping.

PERR# Generation
Enables or disables the PCI device to generate PERR#.

SERR# Generation
Enables or disables the PCI device to generate SERR#.

Relaxed Ordering
Enables or disables the PCI Express device relaxed ordering.

Extended Tag
When this function is enabled, it allows a device to use 8-bit tag field as
a request.

No Snoop
Enables or disables the PCI device’s no snoop option.

Maximum Read Request
Selects the maximum read request size of the PCI Express devices.

ASPM Support
Selects the ASPM level.
Force L0 Forces all links to L0 state.
Auto

The BIOS automatically select an ASPM level.

Disable

Disables ASPM.

Extended Synch
When this function is enabled, it allows generation of extended synchro-
nization patterns.
