You can set keyboard operating characteristics, such as whether the blade server starts with the keyboard number lock on or off. You can enable the blade server to run without a diskette drive or keyboard. You can enable or disable the PXE option for either of the integrated Gigabit Ethernet controllers. The default setting for this menu item is Enabled, which enables the PXE option for the selected controller. To disable this option for a Gigabit Ethernet controller, select Disabled. If you enable the boot fail count, the BIOS default settings will be restored after three consecutive failures to find a boot record. You can enable a virus-detection test that checks for changes in the boot record when the blade server starts. v Advanced Setup Select this choice to change settings for advanced hardware features. Important: The blade server might malfunction if these options are incorrectly configured. Follow the instructions on the screen carefully. - System Partition Visibility Select this choice to specify whether the System Partition is to be visible or hidden. - Memory Settings Select this choice to manually enable a pair of memory DIMMs. If a memory error is detected during POST or memory configuration, the blade server automatically disables the failing memory pair and continues operating with reduced memory capacity. After the problem is corrected, you must enable the memory connectors. Use the arrow keys to highlight the rows representing the pair that you want to enable; then, use the arrow keys to select Enable. - CPU Options Select this choice to enable or disable the microprocessor cache. In addition, you can set the microprocessor cache mode to write-back (WB) or write-through (WT). Write-back caching generally provides better system performance. - PCI Bus Control Select this choice to view and set interrupts for PCI devices and to configure the master-latency-timer value for the blade server. - Integrated System Management Processor Settings Select this choice to enable or disable the Reboot on System NMI option on the menu. If you enable this option, the blade server will automatically restart 60 seconds after the service processor issues a nonmaskable interrupt (NMI) to the blade server. v Error Logs Select this choice to view or clear error logs. - POST Error Log Select this choice to view the three most recent error codes and messages that were generated during POST. Select Clear error logs to clear the POST. v Save Settings Select this choice to save the changes you have made in the settings. v Restore Settings Select this choice to cancel the changes you have made in the settings and restore the previous settings.
