iA. Miller's book on CP/M is pretty good. You might also get source code
from the simtel20 archives. I suggest early stuff by Peteresen or
Christensen.. sources for DU or Plink or Modem before they got cluttered
up by other people. DASM is a good one to look at also. There are a
few sample BIOS floating about also. These tend to be device dependent,
so you would ideally like to find one for a machine using the same
serial and disk controller chips as the system you have. Common disk
controller chips are the Western Digital 179X series. Common serial
chips are the 8250, 8251, 2661, and z80sio. Code for these can also
be found in overlays to MODEM. Disk controller code will probably 
be harder to find.
