Does anyone know of a good cache program that will automatically give up
space?  I have a system with 4 megs of memory, and use QEMM-386 to
convert it to expanded memory.  Since I am usually using less than 2
megs, I would like a cache that takes up almost all of the memory, yet
releases it when expanded memory is needed.  The Smartdrive program that
comes with Windows only works with Windows programs.  It doesn't seem
that this should be too difficult to do (I've done a lot of programming
on the PC).  Are there any reasons not to simply take over the int 67h
vector?  (Of course, putting the right driver code in my own interrupt
handler)  I would then trap all calls.  This driver would return 4 megs
available (or some maximum amount).  Basically, whatever ems isn't being
used would become cache memory.  Now all I need is the source code for a
good pd cache.
    Does anyone know if there is a product that does what I want
(preferably pd or shareware, but I would consider commercial).  I am
using PC-Cache 6.0 right now.  If there is some reason why such a
program hasn't been written, let me know.  Also, if you have any other
ideas for productive (temporary) uses of a couple of megs(other than a
Ramdisk; I have PC-Magazine's resizable Ramdisk loaded, and have never
used it), let me know.
                  Thanks,
                   \\\ Josh ///
