This is more a primer to IBM vocabulary, though. IBM midrange systems also "IPL," like the POWER6 in the next room which isn't a small system but definitely not a mainframe.

> definitely not a mainframe.
Interestingly enough, as part of IBM's Eclipz Project - to share tech between their server lines - the POWER6 shared a lot of things with the z10 mainframe processor. To quote Wikipedia:
"The z10 processor was co-developed with and shares many design traits with the POWER6 processor, such as fabrication technology, logic design, execution unit, floating-point units, bus technology (GX bus) and pipeline design style, i.e., a high frequency, low latency, deep (14 stages in the z10), in-order pipeline. "
Yep, I learned the terms IPL and IML ("Initial Microprogram Load," more akin to a cold boot) when I worked on an IBM midrange system running DOS/VSE back in the 1980s.
