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

BIOS Power-On

Allows you to set the computer to turn on automatically at a time you specify.

 

 

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.
