not surprising.  in addition to boot code being in the MBR, every
partition (IIRC) has a boot sector as well for additional boot code
that might be necessary to boot just that partition.

what you're seeing is undoubtedly MS-DOS boot code left over
from when, as you say, this used to be a DOS machine.  when you
installed linux and made this a linux partition, because
you installed your loader in the MBR (i'm guessing), the
boot sector in this partition was left untouched.  it's
still DOS boot code, it's just being ignored.

this is all speculation, but i'm feeling pretty confident.
