	an extended memory ramdisk of 384k won't necessarily make
	your machine operate faster...  you will gain something if
	your hard disk is really slow (or if you don't have a hard
	disk)...  but the 286 has to reboot and jump through hoops
	to get at the above 1M cache.  not a fast procedure...

	the application and the cache program you use will affect
	your results, too...  if you do as much disk writing as you
	do reading (linking), you may actually get slower performance
	by using an extended memory cache..
