RE: V4R3 alternate IPL device - CDROM

Jerry,

I read your earlier posting and didn't respond because it didn't conform
to my expectations.  What I expect is that on a 'D' IPL the system will
'walk the bus' for all devices which could be bootable.  This should
include both your tape drive and your CD-ROM.  If the tape drive is
varied on without error and contains no tape, the system should move on
to the next possibility.

I don't know if this is helpful or not.  It sounds as though your system
is not behaving as I would have expected.

Regards,
Andy Nolen-Parkhouse
