I have been using MicroSoft's SMARTDRV as a disk cache with DesqView 
in a Zenith 386-16, with no problems.  I presume the same would apply 
to ZCACHE.

I gather you are still using QEMM v 4.2 or earlier.  I highly 
recommend the upgrade to version 5.0.  My experience was that 4.2 was 
cranky, unreliable and slow on my Zenith.  The upgrade improved 
matters enormously.

Since you are emulating expanded memory in your extended memory, I 
woyld recommend removing the /a switches.  All they are doing is 
adding additional overhead.  Use the /EXTMEM parameter on your QEMM 
line to reserve some extended memory.
