Try using DosOpen. The parameter fsOpenMode needs to have the 
OPEN_FLAGS_DASD value included. Just open the drive name, like "C:" instead
of a filename. I played with it and got it to work with little problem. The
boot drive is locked in some manner, so writing could be an issue unless
you boot from floppy. The big benefit here is that normal DosRead/Write/Seek
will work. No fancy programming required. No need for GURUs anymore.

You can also use the DosDevIOCtl function to actually have to worry about
all the stuff you want to bother with. In some situations this could be
a requirement, like recovering a damaged disk, copyprotection, etc.

P97 of OS/2 Programmer's Rev. Vulume 3 talks about OPEN_FLAGS_DASD.
