Table 5-6 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 APIC-based operating system. Device Options Allows you to set: ● 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. ● Processor cache (enable/disable). ● Integrated video (enable/disable) ● Integrated Graphics Memory Size ● Integrated Graphics Engine Clock (dynamic/static) ● 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. ● HPET (enable/disable). Enable/disable the High Precision Event Timer (HPET) for operating system use. ● Synchronize Time with Enclosure (enable/disable) ● USB 2.0 Capability (automatic, enable/disable) ● Automated System Recovery (enable/disable). Enable/disable the ASR feature, which allows you to recover from system lockup. Restoring the Configuration Settings Restoring the configuration settings requires that you first perform the Save To Removable Media command within the Computer Setup (F10) Utility before Restore is needed. NOTE: It is recommended that you save any modified computer configuration settings to removable media, and save the removable media for possible future use. To restore the configuration, insert the removable media with the saved configuration into a USB drive (attached via the diagnostic adapter) and perform the Restore from Removable Media command with the Computer Setup (F10) Utility. 42 Chapter 5 Deployment and Management ENWW
