        Revision B of the beta release includes Martin Harriss's
Mitsumi driver. The Mitsumi drive is detected and used automatically.

        Revision B works with all Mitsumi drives except for the drives
made after March 1993 with serial numbers beginning with "D," presumably
a problem shared by all Linux distributions. These drives are slightly
incompatible.

        I got Mitsumi to release two pages of their drive programming
information to me without a nondisclosure agreement. To support the D
series drives, it looks like you just have to set a bit in one register,
but I haven't had time to implement and test the fix. I've sent details
of the fix to Martin, and I was only able to obtain a D series drive
on Sunday. In the meantime, I would be happy to fax the pages that
Mitsumi sent to me to any other interested Linux hacker.
