Okay, all you IBM PC techno gurus, here is a question for you.  What I have
in mind is this:  Is it possible to create your own device driver, for DOS
or some other OS, that does not use the BIOS but rather communicates directly
with the drive controller and make the drive believe that it is a 1.44M disk?

I have noticed, as I am sure hundreds of other people have, that alot of the
problems of trying to add a higher density drive to a PC is that the BIOS
does not support it.  So, why not bypass BIOS and create your own subroutine(s)
to handle the disk drive.  Outside of the check for the 1.44M hole on the
actual disk, I don't really see any problems in doing this.

If this is possible or it has already been done, I would welcome any pointers
as to where to this driver or source to a driver would reside.

Thanks,
Eric DeVolder
