automatically when the computer system boots up. This allows
the immediate use of the 10-key numeric keypad located on
the right side of the keyboard. To confirm this, the Number
Lock LED light on the keyboard is lit.
Boot From LAN Support [Disabled]
The Boot From LAN Support option enables the system to be booted from a remote
system.
Disabled D EFAULT
Cannot be booted from a remote system through the
LAN.
Enabled Can be booted from a remote system through the
LAN.
Spread Spectrum Function [Disabled]
Use the Spread Spectrum Function option to reduce the EMI. Excess EMI is generated
when the system clock generator pulses have extreme values. Spreading the pulse
spectrum modulates changes in the extreme values from spikes to flat curves, thus
reducing the EMI. This benefit may in some cases be outweighed by problems with
timing-critical devices, such as a clock-sensitive SCSI device.
Disabled D EFAULT
EMI not reduced
Enabled EMI reduced
5.5.2 Boot Device Priority
Use the Boot Device Priority menu (BIOS Menu 16) to specify the boot sequence from
the available devices. The drive sequence also depends on the boot sequence in the
individual device section.
