Hi!

If you say you have a 512 MB BIOS limit, your limit probably
is 512 * 63 * 16 * 1024 bytes, in other words a limit in the
number of "heads" (those do not relate to actual surfaces).

Are you sure FreeDOS is affected when you use LBA? Note that
the limit is only 504 * 1024 * 1024 bytes, so depending on
how you count the 512 MB for the first partition, you might
already be beyond the limit.

And of course you could consider updating your BIOS to fix
the "528 MB" problem, or install a MBR-installed workaround
such as ontrack / ezdrive :-) I wonder if UHDD could help
you, too, as long as the boot files are in the first 504 MB.

You could get yourself a converter to connect SATA drives
(SSD or mechanical) to your IDE computer: I think SATA will
stay available for a long time and you can always use the
first 504 (528) MB even without extra drivers or BIOS fixes.

Typical SATA / IDE converter brands could be DeLock or Digitus,
but be careful to get a converter in the right direction ;-)
Or one which works in both directions, of course. All cheap.

Regards, Eric
