The following are from Programmer's Guid to the IBM PC, Peter Norton:
0x52 - not used
0x5d not used
0x60 - not used
The list stops at 0x62 (get PSP address).  Since Norton gets most of his info 
from the Tech Ref manuals, the other functions are undoubtedly undefine, 
and although they may actually "do something", they are not "official".
