I know that most of you are 8-bit CPMers, but maybe there is someone
out there using CPM-86 (or CCPM-86 or MPM-86) who can help me.  I am using
an Altos 586 running MPM-86.  I have a 20 meg (15 formatted) hard disk, but
I am always almost out of directory entries even though I have only filled
about half the disk.  The problem seems to be that the disk can only have
1024 directory entries and since XFCBs (which give me time/date stamping
and password protection which I really need) nearly double the number of
entries required (especially since I have a lot of little programs, etc.)
I can only have about 500 individual files on the drive.  In MPM-86, XFCBs
are optional but I think they are automatic in Concurrent CPM-86 so I am
probably not the only one with this problem.  MS-DOS doesn't have this problem
because the direectories (except the root) are stored as files.  I don't
need a directory structure - 16 user areas is plenty - but I could really
use the larger directory space.  The Altos manual briefly mentions multiple
logical drives on one physical drive but nowhere in the Altos or DRI
documentation does it say how to do this.  Does anyone know how to get around
this problem ???  Any help will be greatly appreciated.
