This dd command should work with the existing port of Fileutils,
unless the disk in drive A: is unformatted.  You just need to give dd
a file name on drive A:, like this:

	    dd if=c:\test of=a:\file

The BIOS support in djtar sources is in the file oread.c.

I never tried to add such support to dd, so I cannot tell off the top
of my head what changes would be needed.  The best way to achieve the
goal is probably to use the Filesystem Extensions feature to catch the
I/O functions at the low level.  But I didn't try that myself.
