Hello Kevin,

The attached patch used a malloc_low disk sector buffer when the
caller's buffer is not aligned. The read handling is tested with
DOS and the write handling is untested.

There is another problem. The same DOS image as eltorito CD-ROM
causes the same problem, but with atapi. So maybe a shared 2048
byte buffer is needed.
