Int 63 Fn 00  - Bw-tcp - Tcpip.sys - Set Ip Address???                     [N]

   AH = 00h
   DS:BX -> DWORD containing IP address (big-endian)

Return: CF clear if successful
   CF set on error

Note:  the Beame&Whiteside TCP/IP protocol stack uses two consecutive
     interrupts (62h and 63h by default); the BW-NFS client uses a third
     consecutive interrupt (64h by default) if it is loaded
