Hello everybody,
I just wanted to keep you updated on my odyssey. After a lot of
experiments and desperate digging in Ralf Brown's interrupt list, I
found out that my Turbo Pascal compiler is somehow broken. I used inline
assembler to call some Int21h functions, and to my greatest surprise, I
found that the calls returned some data but lines like
MOV result, AX
wouldn't work as expected. I'll look into the compiled code to find out
what the heck is going on there, but for now I just rewrote the code to
use the built-in MsDos() function to call Int21h. With these changes, I
finally got some data that seems to make sense. :)
However, I'm not too happy with what I get. It seems to be a bit
difficult to determine which kind of drive I'm looking at, the only
reliable thing is that I can check if there is a drive at all (carry
flag not set).
Eric suggested to have a look at some sources for a better understanding
of what is going on, I'll post my findings soon :)
Best regards,
Andre
