INT 7F - Alloy NTNX (Slave), MW386 - GET USER PARAMETERS
	AH = 05h
	DX:DI -> buffer for user information record (see #03945)
Notes:	MW386 provides this function for backward compatibility only, and sets
	  many of the fields to zero because they are meaningless under MW386
	this function has no effect when called by the host (user 0)
