Table 3-6Computer Setup—Advanced (for advanced users) (continued)

Onboard Devices

Allows you to set resources for or disable Legacy devices.

 

Select the Legacy device's IRQ, DMA, and I/O Range. The settings may not take effect for all

 

operating systems. To hide a device from the operating system, see Security > Device Security.

 

 

Bus Options

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:

 

● Printer mode (Bi-Directional, EPP + ECP, Output Only). ECP = Enhanced Capabilities Port, EPP

 

= Enhanced Parallel Port. Default is EPP+ECP.

 

● Num Lock State at Power-On (off/on). Default is off.

 

● Integrated Video (enable/disable). Use this option to disable the integrated video controller

 

when another video controller is present in the system. Default is enabled.

 

● Integrated Graphics (Auto/Disable/Force) Use this option to manage integrated (UMA)

 

graphics memory allocation. The value you choose is allocated 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 (does not affect external speakers). Default is enabled.

 

● NIC PXE Option ROM Download (PXE, iSCSI, 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.

 

● SATA RAID Option ROM Download (enable/disable). The BIOS contains an embedded SATA

 

RAID option ROM for RAID support. This can be temporarily disabled to save DCH space.

 

Note that with the option ROM disabled, users will be unable to boot to hard drives in the

 

system while running in RAID mode. Default is disabled.

 

● Multi-Processor (enable/disable). Use this option to disable multi-processor support under the

 

OS. Default is enabled.

 

● Hyper threading (enable/disable). Use this option to disable processor hyper-threading.

 

● Turbo Mode (enable/disable). Allows you to enable and disable the Intel Turbo Mode feature,

 

which allows one core of the system to run at a higher than standard frequency and power if

 

other cores are idle. Default is enabled.
