Int 2F Fn 4A10 - Smartdrv V4.00+ - Installation Check And Hit Ratios [c]
AX = 4A10h
BX = 0000h
CX = EBABh (v4.1+; see Note)
Return: AX = BABEh if installed
DX:BX = cache hits
DI:SI = cache misses
CX = ???
BP = version in BCD (4.10 = 0410h)
Notes: most of the SMARTDRV API, including this call, is supported by
PC-Cache v8.0
if DBLSPACE.BIN is installed but SMARTDRV has not yet been installed,
unless CX=EBABh on entry, DBLSPACE.BIN displays the error message
"Cannot run SMARTDrive 4.0 with DoubleSpace" and aborts the caller
with INT 21/AX=4C00h
SMARTDRV v3.x had a completely different API using IOCTL calls
