INT 21,5E AL=0 Get Machine Name (DOS 3.1+)

   AH = 5E
   AL = 00 get machine name
DS:DX = far pointer to buffer receiving name string

on return:
   AX = error code if CF set, (invalid function)
   CH = 0 if name not defined
      > 0 if name defined
   CL = NETBIOS name number, if CH not 0
DS:DX = far pointer to buffer containing string if CH not 0

- returns pointer to an ASCIIZ string identifying the computer on a Microsoft network
- output string is a 15 bytes long, padded with blanks and null terminated
- unpredictable if called without file sharing loaded
