Table 3-5Computer Setup—Advanced (continued)

Bus Options	On some models, allows you to enable or disable:
	● PCI SERR# Generation. Default is enable.
	● 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. Default is disable.
Device Options	Allows you to set:
	● Num Lock State at Power-On (off/on). Default is on.
	● Parallel Port Mode (EPP+ECP, Output-only, Bi-directional).
	● Multi-Processor (enable/disable). Use this option to disable multi-processor support under
	the OS. Default is enabled.
	● Hyper-threading (Enable/disable). Provides processor parallelization such that the operating
	system treats one processor as two. Default is enable.
	● NIC 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 1 MB 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. Default is-enable.
	● Processor Frequency Multiplier. Accessible using CTRL+A. The frequency multiplier adapts
	the external frequency of the computer to the internal frequency of the processor. This
	setting lets you overclock your computer.
