Select this choice to set passwords. See "Passwords" on page 10 for more information about passwords. You can also enable the chassis-intrusion detector to alert you each time the server cover is removed. - Power-on Password Select this choice to set or change a power-on password. See "Power-on password" on page 11 for more information. - Administrator Password Select this choice to set or change an administrator password. An administrator password is intended to be used by a system administrator; it limits access to the full Configuration/Setup Utility menu. If an administrator password is set, the full Configuration/Setup Utility menu is available only if you type the administrator password at the password prompt. See "Administrator password" on page 11 for more information. v Start Options Select this choice to view or change the start options. Changes in the start options take effect when you restart the server. You can set keyboard operating characteristics, such as the keyboard speed, and you can specify whether the server starts with the keyboard number lock on or off. You can enable the server to run without a diskette drive, monitor, or keyboard. The startup sequence specifies the order in which the server checks devices to find a boot record. The server starts from the first boot record that it finds. If your server has Wake on LAN® hardware and software and the operating system supports Wake on LAN functions, you can specify a startup sequence for the Wake on LAN functions. You can also specify whether the integrated SCSI controller or a PCI SCSI adapter has boot precedence. 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 server starts. v Advanced Setup Select this choice to change settings for advanced hardware features. Important: The server might malfunction if these options are incorrectly configured. Follow the instructions on the screen carefully. - Power Management Setup Select this choice to enable or disable system power settings. This includes automatic power-on settings such as the Wake on LAN feature. - Chipset Feature Select this choice to modify settings that control features of the core chip set on the system board. Attention: Do not make changes in the Chipset Feature option unless directed to do so by an IBM authorized service representative. - Processor Control Select this choice to enable or disable the microprocessor cache and hyper-threading. The default status for hyperthreading is Enabled. Attention: Do not make changes in the Processor Control option unless directed to do so by an IBM authorized service representative. v PC Health Status Chapter 2. Configuring your server 9
