	AX = CA01h
Return: AH = 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. version number (v2.2+)
	    CAh for versions before 2.2
	AL = state (00h = disabled, 01h = enabled)
	CX = number of signatures which will be searched
---v2.0---
	BX = EMSsee Expanded Memory Specification handle, 0000h if not using EMSsee Expanded Memory Specification
---v2.3+---
	BX = segment of swap area, 0000h if not swapped
	DX = EMSsee Expanded Memory Specification or XMSsee Extended Memory Specification handle (XMSsee Extended Memory Specification handle if BX=0000h), FFFFh if not using EMSsee Expanded Memory Specification
