Service Processor: Enables you to update service processor
firmware.
Service Processor should be selected only when a change to
the service processor firmware is needed. A
Service Processor
Update diskette will be made available to you when such an
update is needed.
Service processor updates take several minutes, and you need
a DOS formatted 1.44MB diskette. The procedure for updating
the service processor firmware is as follows.
Attention: Do not turn off power to your system during this
procedure.
1. Select Tools, and then Service Processor.
2. Make a backup copy of the service processor firmware
using a DOS formatted 1.44MB diskette as prompted. This
backup is a Service Processor Firmware Diskette that may
be used later to recover from system problems.
3. When the backup is complete, insert the Service Processor
Firmware Update diskette. The service processor firmware
will be updated, and the system will automatically restart
upon completion.
RIPL: Allows you to select a remote system to load programs
from when your system is first powered on.
Overriding the Stored Boot Sequence
In order to override the stored boot sequence for the current boot, press F5 after the
keyboard indicator appears on the screen, but before the last indicator appears. This
forces the firmware to search for startup code on the devices listed in the default
sequence, either diskette, CD-ROM, hard disk drive, or token-ring (if installed) or
ethernet (if token-ring is not installed). Pressing F5 does not modify what has
already been selected through “Start Up” on page 5-4. That information is still
stored in the system. Pressing F5 is limited to the current boot.
