IPL = Initial Program Load = boot(strap), by the way. It also has the

IPL is one of several IBM-isms. A few others:
main storage = memory. IBM considered "memory" too anthropomorphic.
DASD = direct access storage device = disk. This is a hold-over from
the days when, in addition to disks, there were drums and the IBM 2321
data cell drive (aka the noodle-picker). DECtape would probably be
classified as DASD.
