>From HELP CPSET MITIME:
2. The system default values at IPL time are:
SET MITIME DASD 00:15*
SET MITIME GRAF 01:10
SET MITIME UR 01:00
SET MITIME TAPE 10:00
SET MITIME SWITCH 05:00
SET MITIME MISC 12:00
*The DASD and TAPE system default values will be used only if the
device subsystems do not return a primary time-out value for the
missing interrupt handler.

Richard Schuh
