I've got a question: Is there a (public) specification document
available somewhere for the loadparm field?
Unfortunately there does not seems to be any kind of documentation
regarding loadparm for
KVM on IBM z. Most of the information available on the IBM Knowledge
Center focuses on
z/VM, which isn't very helpful in this case :(
Ok, too bad :-(
Are there any specific questions that I can help with?
I was just wondering whether there are pre-defined values for this
field, e.g. is "PROMPT" something you came up with, or is this a value
that has been documented in a specification somewhere? ... I'm just
curious: If there is a list of pre-defined values somewhere, what are
the other values that the s390-ccw bios does not support yet?
