INT 21/AX 3567 will return a pointer in ES:BX that can be used to
determine EMS availability.  That should point (I think) to the EMS
device header where you should find something like EMMXXXX0.

If he's in BASIC, you might have him try the following:

OPEN "EMMXXXX0" FOR INPUT AS #1 : CLOSE 1

If the EMS driver isn't there, a 'File Not Found' error will occur.
