Actually, the logical sector size was also increased to 1024 bytes, along
with some other modifications.  Maximum partition size is now 1024 Megs,
or 1 gig.  I'm presently running off of a 40 meg partition, and I wouldn't
go back for anything.

The big problem now is that the program may not be able to deal with the
1024 byte logical sectors, since most just assume 512 byte sectors.  The
physical sectors, however, are still 512 bytes.

Never seen this problem, even though I've still got 1.2. Hmmm.
