Re: PDOS/3x0 on real hardware

I dont know ... its done in microcode...

"To convert 9313, 9332, or 9335 devices to usable CKD devices, you must
have loaded the correct microcode level. For more information, contact your
IBM service representative.

If the emulated device has never been initialized after conversion to CKD
emulation, the device is unusable. To avoid unpredictable results, run a
medial INIT before running any other command."
