Int 7A  - Novell Netware - Spx Driver - Installation Check                 [N]

   BX = 0010h
   AL = 00h

Return: AL = FFh if SPX loaded
       BH = SPX major version
       BL = SPX minor version
       CX = maximum SPX connections
       DX = SPX connections available

Note:  this function is supported by Advanced NetWare 2.1+
   this interrupt is used for IPX/SPX access in NetWare versions through
     2.0a; in later versions, you should use INT 2F/AX=7A00h to get an
     entry point even though INT 7A still exists.  For both INT 7A and
     the FAR entry point, BX contains the function number; IPX is
     sometimes called internally with BX bit 15 set.
