Steven Smith argues that I was wrong about the BUFFERS with the /X
option.  In his MANIFEST display he shows how using the /X option
frees up base memory.  That is true.  But look what happened to the
NUMBER of buffers:  BUFFERS=30/X.  That isn't what you specified in
your CONFIG.SYS, Roger.  You specified 20.

I am not talking about freeing up memory.  I'm talking about the fact
that disk caches work better when you set the DOS buffers to a small
number.  HyperDisk works best with the DOS buffers set to 5.  Using
the /X option in the BUFFERS command in CONFIG.SYS causes DOS to
allocate 30 buffers NO MATTER HOW SMALL A NUMBER YOU SPECIFY.  That
spoils the performance of HyperDisk and probably most other disk cache
programs.
