- System MAC Addresses Select this menu item to set and view the MAC addresses for the Ethernet controllers on the blade server. Note: MAC addresses are displayed only for those devices with PXE enabled v Date and Time Select this menu item to set the system date and time, in 24-hour format (hour:minute:second). v System Security Select this menu item to set a power-on password. See "Using passwords" on page 18 for more information about passwords. v Start Options Select this menu item to view or change the start options. Changes in the start options take effect when you start the blade server. - Startup Sequence Options Select this menu item to view the startup device sequence that is set for the blade server. 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 all of the Ethernet controllers in the blade server. The default settings enable the PXE option for the two Ethernet controllers on the system board. 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 menu item to change settings for advanced hardware features. Important: The blade server might malfunction if these settings are incorrectly configured. Follow the instructions on the screen carefully. - Memory Settings Select this menu item to manually enable a pair of memory connectors. If a memory error is detected during POST or memory configuration, the blade server automatically disables the failing pair of memory connectors and continues operating with reduced memory. After the problem is corrected, you must enable the memory connectors. Use the arrow keys to highlight the pair of memory connectors that you want to enable, and use the arrow keys to select Enable. To maintain optimum system operation in the event of a memory failure, you can set memory configuration to mirroring or sparing. Memory mirroring stores duplicate data on two DIMMs to prevent data loss if a DIMM fails. Memory sparing removes the failed memory from the system configuration and activates a hot spare pair of DIMMs to replace the failed pair of DIMMs. Before you can enable memory mirroring or sparing, at least two pairs of DIMMs must be installed in the blade server that adhere to the special requirements that are described in "Installing a memory module" on page 46. Set Memory Configuration to Flat to disable memory mirroring and sparing. - Microprocessor Options Chapter 3. Configuring the blade server 17
