Subject: SmartDrive Interface

   FYI, the IOCTL interface is no longer the way to talk to SmartDrive.
   It worked for old versions of the cache (before 4.x, which came with
   DOS 6.x and Windows 3.1x).  You can see what version your cache is by
   typing the following words of wisdom from the DOS command prompt:

	   smartdrv /s

   If this prints version 4.x (Windows 3.1x) or 5.x (DOS 6.2x), then the
   IOCTL interface is not for you.

And what if smartdrv /s doesn't work, because it's smartdrv.sys?
(This is the case with IBM DOS/V 5.x.)  Presumably the IOCTL interface
will work, but....  Obviously IBM and Microsoft have somewhat
different philosophies on this; do you know if smartdrv is the same
across those two implementations of DOS?
