     No.

|Did you use PARTED?

     No.

|Did you use Partition Magic?

     No.

|Are you using an LBA geometry translator?

     Um, not to my knowledge.  I don't know what
an LBA geometry translator is.  Does it have something
to do with hyperspace?  8^)

|Are you using a Prmis EIDE controller?

     No.

     I've seen several responses to my email and 
I haven't done any of the things that are supposed
to cause a problem.  However, from checking every
piece of information I have been able to find, and
combining it with my empirical data, I have a theory.

     I believe the problem was simply that I created
a DOS partition (using fdisk) that was bigger than
1GB.  I don't know enough about MS-DOS filesystem
architecture to understand why this might be a problem,
but it seems like it is.  I deleted the old partition
and created a new one just under 1GB, and everything's
fine.

     Can anyone corroborate or repudiate my little
theory?
