If all types of devices in the boot list have been polled without finding a bootable
image, the system restarts, this gives the user the opportunity to start the System
Management Services ( by pressing the F1 key on a directly attached keyboard or
the number 1 on an ASCII terminal) before the system attempts to boot again.
Default Boot List and Service Mode Boot List
The default boot list is:
1. Diskette
2. CD-ROM
3. Tape
4. Hard File
5. Network
Token-Ring
Ethernet
Pressing the F5 key on a directly-attached keyboard (or the number 5 key on an
ASCII terminal) causes the system to load Standalone Diagnostics given that a
Diagnostic CD is present in the CD-ROM drive.
Pressing the F6 key on a directly-attached keyboard (or number 6 key on an ASCII
terminal) loads Online Diagnostics from the service mode boot list, no Diagnostic
CD should be in the CD-ROM drive since Online Diagnostics is typically run from a
hard disk, which is in the service mode boot list defined using the system diagnostics
"Display or Change Bootlist" service aid. Like the default boot list, the service mode
boot list can contain five entries. The F6 or 6 keys work like the F5 or 5 keys, with
the following exceptions:
The system searchs for a boot record according to the service mode boot list.
If the service mode boot list is discovered by a cyclical redundancy check to be
corrupted, the system rebuilds the service mode boot list according to the default
boot list. (The default boot list contains five entries, and for each matching
device type found in the system unit, the system makes an entry in the service
mode boot list.)
If no service mode boot list is present, the system uses the default boot list.
