I mentioned this to a Solaris developer who said, "Oh, sure; it just takes about a quarter megabyte support code in the boot record." If IBM had a similar level of commitment to PDSE it would be possible to IPL a system with _no_ PDS; only PDSE (or even only zFS (that one)).
But it all depends on proper layering; it would require that very early in Nucleus Initialization components begin using access methods, not STARTIO nor RYO channel programs. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
