Thank you all that replied to my original question on implementing multiple
formats on 8" disks under CP/M. There are it seems two major ways in which
to do this. The first being to place a label at some known location on the
disk (i.e. The last n Bytes in Sector 0, Track 0) which contains either the
floppy format or the actual DPB and DPH to use. I am going this route since
Cromemco also uses it and I may wish to read CDOS disks on my system. The
second somewhat easier method is to define the same physical drive multiple
times with various formats. For instance A: is SSSD but E: is physically
the A drive but accessed as DSDD. Thanks also for the note about when to
flush multisector buffers out to disk.
