INT 2F U - Novell NetWare - SNMP.EXE - INSTALLATION CHECK                       
	AX = 7A4Fh
	BX = 0001h
Return: AX = 7AFFh if installed
Note:	this call conflicts with RARPD.EXE (both SNMP and RARPD are supplied
	  with LAN Workplace for DOS!), such that running SNMP will uninstall
	  RARPD as SNMP checks whether it is already installed!
