Subject: CPM/BIOS interface questions

I need some information about what CP/M (2.2) expects
from the BIOS. Specifically:

       What are the various entries in the disk parameter
       header blocks? (and what does CP/M do with them)

       What kind of error codes does CP/M want for things
       such as 'write-protect', or 'record-not-found', etc.?

Please respond via email to me, since I don't get too many chances
to read this group.
