Dear Maintainer,

This is a strange one. The version of dosbox-x itself appears to have not
changed, but the packaging has. It stopped being possible to mount a disk
that doesn't devide evenly into sectors, heads, and cylinders (which will
typically be the case for a disk of an even number of GB in size).

Previously, using int 13h, ah=42h,43h,48h the entire disk would be
accessible despite what the geometry says. Now, the disk is clamped to its
geometry, cutting off the last sectors (which may be a lot).

This is incredibly frustrating as I currently posess the only working
FAT disk check that doesn't do the stupid thing on SSDs; and its own FAT32
unit tests can't be ran using dosbox-x anymore because of this bug.

The upstream version of dosbox-x has very recent changes to it to disk
size handling; but the version here is clearly last year's version.
