I know this may be an FAQ, but I am just a little confused.  Is
LOADALL implemented in the 486?  PC Magazine said that it is
in all processors from 2-486.  It also said that Microsoft use
the instruction in HIMEM.SYS, SMARTDRV.SYS and RAMDRIVE.SYS in
MS-DOS.  On the other hand, an instructor from Intel (while lecturing
on an i386/486 programming and architecture course) alleged that
LOADALL is only there on 286 and earlier steps of the 386.  Does
anybody know the REAL answer?  Is there commercial software out
there that does use this reserved instruction.  This enquiry is
out of curiosity only - I have no intention of putting LOADALL
into any of my programs!

Please mail me.
