You did not say if you were running AOS or AIX, but on an RT running
AIX, you CAN set the nvram to indicate the boot device.
Under AOS, your milage may vary. :-)
The following key sequences are documented in the VRM programming
reference appendix C.
The folowing keyboard key sequences only update the data in NVRAM.
CTRL+ALT+a update nvram for diskette drive #1
CTRL+ALT+b update nvram for diskette drive #2
CTRL+ALT+c update nvram for fixed-disk device #1
CTRL+ALT+d update nvram for fixed-disk device #2
CTRL+ALT+e update nvram for fixed-disk device #3
These are other key sequences that are also defined:
CTRL+ALT+PAUSE performs soft re-ipl of cpu. re-ipl vrm and initate
ipl from default IPL sequence or from defined sequence
set by CTRL+ALT+(a,b,c,d,e)
CTRL+ALT+HOME perform re-ipl of virtual machines, does not re-ipl VRM.
CTRL+ALT+'pad 6' Power-on-reset ipl. same as power on sequence.
CTRL+ALT+'pad 7' perform VRM dump of real memory to floppy dump diskettes.
CTRL+ALT+'pad 8' perfomr dump of selected areas of memory
CTRL+ALT+'pad 4' invoke VRM debugger (if loaded)
CTRL+ALT+END perform dump of first virtual machine.
CTRL+ALT+DEL perform IPL of optional co-processor.
CTRL+ALT+ACTION exits co-processor mode.
This has gotten quite a few people over time. :-)
Later,
Markw
