sysgen of MVS3.8

Stefan Skoglund All Messages By This Member #3102 Reading Jays page about bootstraping MVS and how his handled the different card decks, is it possible to bootstrap from only one card reader, the 3505 one on localhost ? and so use nc localhost < inspool0.job Instead of the four 1441 devices ? ie to emulate as far as possible the feel of running a machine with one or two card readers, a punch, two tapes and a bunch of 3350 disks.

Answers to myself (maybe) : do the prepackaged mvs in the install tapes know how to speak to the 3505's internal controller ?

Normally IO only speaks to a device, and the SIO and CCWs are pretty much standard across devices. I would be very surprised if the device type matters. Dave
Joe Monk All Messages By This Member #3106 Nope. The tapes that are used for the SYSGEN are IPL'able.
