> SL: What exactly can it do? List of commands, please? 
 
Never seen a list (would dearly love to see one), but the two I do know of 
are the sleep call: 
 
  DX:AX = milliseconds, 
  HLT 
  DB 35H,0CAh 
 
(I'd suggest following this one with an extra 90H, just so that it will run  
if OS/2 isn't there without causing weird sorts of problems.) 
 
and the terminate call: 
 
  XOR AX,AX 
  HLT 
  DB 02H,0FDH
