Table A-3 Computer Setup—Advanced (for advanced users) (continued)
Bus Options On some models, allows you to enable or disable:
Device Options Allows you to set:
PCI SERR# Generation. Default is enabled.
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 disabled.
Printer mode (Bi-Directional, EPP + ECP, Output Only). Default is EPP+ECP.
Num Lock State at Power-On (off/on). Default is off.
Integrated Graphics (Auto/Force). Use this option to manage integrated (UMA) graphics
memory allocation. The value you choose allocates memory permanently to graphics and is
unavailable to the operating system. For example, if you set this value to 512M on a system
with 2 GB of RAM, the system always allocates 512 MB for graphics and the other 1.5 GB for
use by the BIOS and operating system. Default is Auto which sets memory allocation to 512
MB.
If you select Force, the UMA Frame Buffer Size option displays, which lets you set the UMA
memory size allocation between 32 MB and 1 GB.
Internal Speaker (some models) (does not affect external speakers). Default is enabled.
Multi-Processor (Enable, Disable) Default Enabled; Use this option to disable multiprocessoe
support under the OS.
NIC Option ROM Download (PXE, disabled). 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. Default is PXE.
