Table 3-6 Computer Setup-Advanced (for advanced users) (continued) PCI Devices ● Lists currently installed PCI devices and their IRQ settings. ● Allows you to reconfigure IRQ settings for these devices or to disable them entirely. These settings have no effect under an ACPI-based operating system. PCI VGA Configuration Displayed only if there are multiple PCI video adapters in the system. Allows you to specify which VGA controller will be the "boot" or primary VGA controller. NOTE: In order to see this entry, you must enable Integrated Video (Advanced > Device Options) and Save Changes and Exit. Bus Options On some models, allows you to enable or disable: ● PCI SERR# Generation. ● 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. Device Options Allows you to set: ● Printer mode (Bi-Directional, EPP + ECP, Output Only). ● Num Lock State at Power-On (off/on). ● S5 Wake on LAN (enable/disable). ◦ To disable Wake on LAN during the off state (S5), use the arrow (left and right) keys to select the Advanced > Device Options menu and set the S5 Wake on LAN feature to Disable. This obtains the lowest power consumption available on the computer during S5. It does not affect the ability of the computer to Wake on LAN from suspend or hibernation, but will prevent it from waking from S5 via the network. It does not affect operation of the network connection while the computer is on. ◦ If a network connection is not required, completely disable the network controller (NIC) by using the arrow (left and right) keys to select the Security > Device Security menu. Set the Network Controller option to Device Hidden. This prevents the network controller from being used by the operating system and reduces the power used by the computer in S5. ● Multi-Processor (enable/disable). This option may be used to disable multi-processor support under the OS. ● Internal Speaker (some models) (does not affect external speakers). ● NIC PXE Option ROM Download (enable/disable). 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. 18 Chapter 3 Computer Setup (F10) Utility
