Man keyboard gives the following possibilities, I'm thinking that you
could use these after turning the machine on (even though it won't boot):
 
Ctrl-Alt-Home     ... If diskette #1 ... that virtual machine is IPLed.
 
... The system first checks diskette drive #1 for a valid IPL record, then
the second device, then each of the fixed disks.
 
Ctrl-Alt-A        ... Designates diskette drive #1 as the second device ...
Ctrl-Alt-B        ... Designates diskette drive #2 as the second device ...
Ctrl-Alt-C        ... Designates fixed-disk drive #1 as the second device ...
Ctrl-Alt-D        ... Designates fixed-disk drive #2 as the second device ...
Ctrl-Alt-E        ... Designates fixed-disk drive #3 as the second device ...
