hdparm is a program that interfaces directly with the hard disk under
Linux. One of the things it can do is set that an IDE disk should 
spin down after a certain idle time.

This is something that I've been missing in DOS. So wildly extracting
from the Linux kernel and the hdparm program sources, I've managed to
get it working. However what I've done is to take only the things 
needed to make it work for me; basically five calls to outportb.

Now I'd like to generalise it back to its glorious shape it came 
from. But how do I get which physical IDE disk and partition 'c:' or 
'g:' is? For those who knows about Linux, I need a mapping from 
DOSish letters to /dev/hd{a,b,c,d}.


Hoppla,
