You can select keyboard operating characteristics, such as the keyboard speed.
You also can specify whether the keyboard number lock starts on or off. You also
can enable the server to run without a diskette drive, monitor, or keyboard.
The server uses a startup sequence to determine the device from which the
operating system is loaded. For example, you can define a startup sequence that
checks for a startable diskette in the diskette drive, then checks the hard disk
drive in bay 0, and then checks a network adapter.
If your server contains Wake on LAN hardware and software and your operating
system supports Wake on LAN functions, you can also define a startup sequence
for the Wake on LAN functions.
If the Boot Fail Count choice is enabled, you can restore the BIOS system
defaults after three consecutive boot failures. If this choice is disabled, the BIOS
system defaults can be loaded only from the Configuration/Setup Utility main
menu.
You also can select whether the integrated SCSI controller with RAID capabilities
or a PCI SCSI adapter is given boot precedence. Select
Planar SCSI to give the
integrated SCSI controller with RAID capabilities boot precedence. If a PCI SCSI
adapter is to be given boot precedence, select the slot number where this
adapter is installed.
You can enable a virus-detection test that checks for changes in the master boot
record at startup.
v
Advanced Setup
Select this choice to change values for advanced hardware features, such as
cache control, and PCI configuration. This choice appears only on the full
Configuration/Setup Utility main menu.
A warning message appears above the choices on this menu to alert you that the
system might malfunction if these options are configured incorrectly. Follow the
instructions on the screen carefully.
– System Partition Visibility
Select this choice to indicate whether the System Partition is visible. To make
the System Partition visible, set this choice to
Visible . To make the System
Partition invisible, set this choice to Hidden . See “Using the ServerGuide
Setup and Installation CD” on page 18 for additional information about the
System Partition.
– Memory Settings
Select this choice to manually enable a pair of memory connectors.
If a memory error is detected during POST or memory configuration, the
server will automatically disable the failing pair of memory connectors and
continue operating with reduced memory capacity. If this occurs, you must
manually enable the set of memory connectors after the problem is corrected.
Select
Memory Settings from the Advanced Setup menu, and use the arrow
keys to highlight the pair of memory connectors that you want to enable; then,
use the arrow keys to select
Enable .
– CPU Options
Select this choice to indicate whether the microprocessor serial number in the
microprocessor is readable or to set the microprocessor cache mode to
disabled, write-back, or write-through. Selecting write-back mode will provide
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 server.
