Table A-6 Computer Setup—Advanced (for advanced users) (continued)Onboard Devices Allows you to set resources for or disable Legacy devices.Allows to you change voltage settings for serial ports A, B, C, and D. Available voltage settingsare:● 0v (default)● +5v● +12vBus 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 configurationspace; 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 controllerwhen 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 andis unavailable to the operating system. For example, if you set this value to 512M on asystem with 2 GB of RAM, the system always allocates 512 MB for graphics and the other1.5 GB for use by the BIOS and operating system. Default is Auto which sets memoryallocation to 512 MB.If you select Force, the UMA Frame Buffer Size option displays, which lets you set the UMAmemory 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 embeddedNIC option ROM to allow the unit to boot through the network to a PXE server. This istypically used to download a corporate image to a hard drive. The NIC option ROM takes upmemory 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 thisembedded NIC option ROM thus giving more DCH space for additional PCI cards which mayneed option ROM space. The default will be to have the NIC option-ROM-enabled. Default isPXE.● SATA RAID Option ROM Download (enable/disable). The BIOS contains an embeddedSATA RAID option ROM for RAID support. This can be temporarily disabled to save DCHspace. Note that with the option ROM disabled, users will be unable to boot to hard drives inthe system while running in RAID mode. Default is disabled.● Multi-Processor (enable/disable). Use this option to disable multi-processor support underthe 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 ifother cores are idle. Default is enabled.56 Appendix A Computer Setup (F10) Utility
