Upgrade to 4.01, which includes SMARTDRV.SYS, a disk cache device driver.
Performance index, as returned by CORETEST went from 6 to 30, before and after
cacheing.  Transfer rate went from 800,000 bytes/second to 5Mbytes per second.
SMARTDRV works in extended memory, and may work in expanded memory, but I'm
to lazy to look in the book to see.


Chewey, get us outta here!
