Microsoft Realtime Compression Interface (MRCI) - RAM-BASED SERVER

AX = 4A12h
CX = 4D52h ("MR")
DX = 4349h ("CI")

Return:
CX = 4943h ("IC") if installed DX = 524Dh ("RM") if installed ES:DI -> MRCINFO structure (see #00725 at INT 1A/AX=B001h)

Note: This call is functionally identical to INT 1A/AX=B001h, but should be called first, as the latter call is used for the first, ROM-based MRCI server, while this call is used for RAM-based servers which may be partially or entirely replacing a prior server
