A previous message mentioned that the author knew of no PC cache software
that did read-ahead caching.

I'm using the Toshiba edition of the PC-Kwik Power Pak from Multisoft
Corp.  Quoting from their manual,
	/T[+|-]	enables/disables track reads.
		MS-DOS frequently requests data from nearby sectors
		soon after requsting a given sector, so reading the rest
		of the track in advance usually increases performance.
		...
		In almost all cases, reading the entire track improves
		the overall performance of your applications.

Makes sense to me.  I'm using it.  It works.  Haven't done any benchmarks
comparing with vs. without track buffering.  I can hear the disk heads move
in my T1200 and they move much less often since I installed the cache.
