    *********************************************************************
    * YOU ONLY NEED TO USE THIS PATCH IF YOU HAVE AN OPTICAL DISK DRIVE *
    *  AND WISH TO BOOT SHAPESHIFTER FROM A MAC-FORMATTED OPTICAL DISK. *
    *********************************************************************

There are several types of SCSI device. For example, hard disks are type 0
(direct access), CD-ROM drives are type 5, and some optical drives are type 7
(optical memory).

Ever since version 3.4, the ShapeShifter Macintosh emulator can only boot
from direct access (type 0) SCSI devices. That is, from e.g. hard disks.

Some optical drives are type 7 (optical memory), and some DVD-RAM and PD
drives report themselves as type 5 (CD-ROM). ShapeShifter refuses to boot
from a Mac-formatted optical disk unless your optical drive is type 0. This
is annoying.

I have figured out patches for ShapeShifter versions 3.10 and 3.11 to not
check the device type when booting.

There are several other deficiencies in ShapeShifter's device handling, but
this patch does not address those.
