●
Lists currently installed PCI devices and their IRQ settings.
●
Allows you to reconfigure IRQ settings for these devices or to disable them entirely. These
settings have no effect under an ACPI-based operating system.
Displayed only if there are multiple PCI video adapters in the system. Allows you to specify which
VGA controller will be the "boot" or primary VGA controller.
NOTE: In order to see this entry, you must enable Integrated Video (Advanced > Device
Options) and Save Changes and Exit.
On some models, allows you to enable or disable:
●
PCI SERR# Generation.
●
PCI VGA Palette Snooping, which sets the VGA palette snooping bit in PCI configuration
space; only needed when more than one graphics controller is installed.
Allows you to set:
●
Printer mode (Bi-Directional, EPP + ECP, Output Only).
●
Num Lock State at Power-On (off/on).
●
S5 Wake on LAN (enable/disable).
◦
To disable Wake on LAN during the off state (S5), use the arrow (left and right) keys to
select the Advanced > Device Options menu and set the S5 Wake on LAN feature to
Disable. This obtains the lowest power consumption available on the computer during
S5. It does not affect the ability of the computer to Wake on LAN from suspend or
hibernation, but will prevent it from waking from S5 via the network. It does not affect
operation of the network connection while the computer is on.
◦
If a network connection is not required, completely disable the network controller (NIC)
by using the arrow (left and right) keys to select the Security > Device Security menu.
Set the Network Controller option to Device Hidden. This prevents the network
controller from being used by the operating system and reduces the power used by the
computer in S5.
●
Multi-Processor (enable/disable). This option may be used to disable multi-processor support
under the OS.
●
Internal Speaker (some models) (does not affect external speakers).
●
NIC PXE Option ROM Download (enable/disable). The BIOS contains an embedded NIC
option ROM to allow the unit to boot through the network to a PXE server. This is typically
used to download a corporate image to a hard drive. The NIC option ROM takes up memory
space below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This
space is limited. This F10 option will allow users to disable the downloading of this
embedded NIC option ROM thus giving more DCH space for additional PCI cards which may
need option ROM space. The default will be to have the NIC option-ROM-enabled.
