Why, that's perfectly ok... Just imagine your feeling if it also did:
outb $al,0x70, outb al, 0x71

;-))

That only goes to show what a crappy piece of !@#$@$% Winword 2000 is...

BTW: Thanks!! This will most certainly fix my JTAG parallel port
flashing tool (I already reported it, but nobody fixed it,
and the result of "time * need" was too low...).

That looks like a "read realtime clock/CMOS" function. Now WHY an 
application would be directly reading the RTC....

Its office suckage.

The function is somewhere around:

MSO9.DLL.?AccessGet@CFileFolder@@QBE?AW4ACCESSQCFSObj@PAviIntterruptQ@@PAH@Z

It is accessing offsets 0x15, 0x16, 0x17, 0x18.

(base memory size and extended memory size?)

Do we have any tools that can demangle MSVC++ symbol names? c++filt won't
do it unfortunately.
