I'd like to find (or build) CP/M for my only S-100
box (you know, the one
 with the Ithaca Audio CPU card).  I have a BASIC boot disk for the
 machine, and I believe I can read/write the 5.25" floppy from my PC
 (via 22disk), but I have no idea what's involved in finding or building a
 CBIOS for this box and where the boot sector on the floppy is. 
The documentation for CP/M 2.2 is online at the unofficial CP/M web site.
See 
http://cdl.uta.edu/cpm/download/manuals/cpm22/index.html. You are
interested in Chapter 6 and most of the appendices.
