	AX = 2763h
	CL = 01h
	BX = signature AAFFh
Return: AH = 00h if VIDEMS is installed
	    CH = 00h if optimization for 80286 is used, 01h otherwise
	    CL = internal revision number (typically 00h to 03h)
	    DX = driver version (DH=major, DL=minor; not a BCD(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits.  Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file.!)
	AH = 84h if not installed but EMSsee Expanded Memory Specification manager is present
Program: VIDEMS is an expanded memory manager from Conea Software Corp. It
	 converts video adapter RAM(Random Access Memory)	See also DRAM, SRAM. to LIM 3.2 EMSsee Expanded Memory Specification.
