Why does my 8.2-RC3 dvd1 boot DOS?

[Chuck Bacon]

SERIOUS APOLOGIES!  I've found out my dvd is marginal, or
possibly the drive.  What seemed like a bad dvd apparently
resulted in a scan (by the BIOS?) until it found a boot loader
it understood, "PC-DOS" it said, which was one of several I
discovered in grepping the ISO file.  I should have
done freebsd-update !
