The vendor of the HDC usually provided a BIOS in source that had to be added
to the system BIOS to connect the drive.  I would assume that it would be
possible to boot off the HD, but none of the systems I every used did (S-100
systems with Advanced Digital, Morrow, and Jade HDC's).  The AD HDC came with
autoinstall software; the other two required revisions of the BIOS.  One of the
last books about CP/M to be published had a BIOS based on the JADE controller.
I believe that old SIG/M and CP/MUG disks may also have BIOSes.
