This is excellent, I was not aware of this program.  Very nice.

Ah, great.  more information that I did not know.   These tools rock.  Also,
Peter was kind enough to point out the memory map function that some DOS
applications (like the Disk Drive Diagnostic Disks) are seemingly failing to
use (INT 15h, AX=E820h), so I can go hassle the vendors.  As if they care.

The next thing for an ultimate boot disk:  Is it possible to mix booting of
floppy and ISO images?  Of will I need to do surgery on the iso to extract
the bootable hunk from the ISO to point to syslinux?  I'm still trying to
educate myself on all of the subleties of the boot process.  Looks like
everything keeps falling back to emulating the lowers common denominator
boot block, and chaining.

Another feature request, which may not be possible:  I'd love the bootloader
to pick images out of an IMG subdirectory (I'm a big fan of "folders only"
in the root).    Between the size constraing and the broad number of
possible disk formats, this may not be possible.  But it would be cool, and
appeal to my pathological inner neatnik.
