Hello David!

CACHEnnn.PRG from Atari increases the number of disk-buffers which will be
used by GEMDOS to cache the FAT- and DATA-sectors (including the directory-
sectors). I don't know the ICD-driver, but I think it will cache the HD-sectors
internally, so if you use CACHEnnn.PRG and the cache in the ICD-driver you wast
only memory. The search-algorithm for cached-sectors is very good in TOS 1.4,
so I prefered it.
