ZCACHE/Desqview combination on a 386 safe?

I have a Zenith 386 (16Mhz) running Desqview under qemm (both hardware and software are a couple of years old). I recently installed zenith's disk cache, ZCACHE, and it has produced some dramatic speedups. But I'm nervous, because I recall that desqview does some of it's own buffering. Also, I've used loadhi for the drivers. Is this combination safe? A portion of my config.sys is DEVICE=C:\DV\QEMM.SYS MAPS=10 RAM NOSORT X=C000-C9FF X=E000-F07F device=c:\dv\loadhi.sys c:\mouse\mouse.sys device=c:\dv\loadhi.sys \dos\vdisk.sys 500 /a device=c:\dv\loadhi.sys \dos\zcache.sys 700 /a FILES=40 BUFFERS=3 This raises an additional question: the documentation implied /a (use expanded memory) was safer than extended memory. Does anyone have experience or wisdom about using expanded v. extended memory? Thanks.

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. > This raises an additional question: the documentation implied /a (use > expanded memory) was safer than extended memory.

All they are doing is adding additional overhead. Use the /EXTMEM parameter on your QEMM line to reserve some extended memory. -- Dr. Noel Roy bitnet: NOELROY@MUN Department of Economics internet: noelroy@kean.ucs.mun.ca Memorial University of Newfoundland cdnnet: noelroy@kean.mun.cdn St. John's, Newfoundland A1C 5S7 Canada
