Computer Setup—Advanced
NOTE: Support for specific Computer Setup options may vary depending on the hardware configuration.
Table B-3 Computer Setup—Advanced (for advanced users)
Option Heading
Power-On Options Allows you to set:
●
POST messages (enable/disable). Default is disabled.
●
After Power Loss (off/on/previous state). Default is Power off. Setting this option to:
◦
Power off—causes the computer to remain powered off when power is restored.
◦
Power on—causes the computer to power on automatically as soon as power is restored.
◦
Previous state—causes the computer to power on automatically as soon as power is restored,
if it was on when power was lost.
NOTE: If you turn off power to the computer using the switch on a power strip, you will not be able to
use the suspend/sleep feature or the Remote Management features.
●
POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POST process.
This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly, so slowly
that they are not ready to boot by the time POST is finished. The POST delay also gives you more
time to select F10 to enter Computer (F10) Setup. Default is None.
BIOS Power-On Allows you to set the computer to turn on automatically at a time you specify.
Bus Options On some models, allows you to enable or disable:
●
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.
Device Options Allows you to set:
●
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.
●
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.
