Hullo All , hope you are having a nice day!!
Well, I read in my book of ASM something about the MRCI (Microsoft
Real-Time Compression Interface)....
The fact is that it said that it was loaded in almost every machine, but
several machines were tested, and the MRCI was not supported...
The MRCI can be served by the BIOS or by the OS, and in all cases it was
not supported neither by the BIOS nor by the OS...
Someone in Argentina suggested me to change the options with which I load
DRVSPACE, but I don't know....
Why can't I detect the MRCI?
Here are the mini-programs I made... The first one checks if it is
supported by the OS, and the second one checks if it is supported by the
BIOS....
/* (MRCI.ASM)
.model tiny

.startup
        mov cx, OLD_CX
        mov dx, OLD_DX
        mov ax,4a12h
        int 2fh
        cmp cx, NEW_CX
        jne not_present
        cmp dx, NEW_DX
        jne not_present
        mov dx, offset it_is_present
        jmp output
not_present:
        mov dx, offset it_is_not_present
output:

Thank you in advance! :)
