  RTFM. Dos 3.3 can access up to 4 partitions of up to 32MB each. There
is no restriction to the boot partition. DOS extenders allow larger
partitions, but don't get past the true limit of no more than 65535
"things" on a partition, where things are files, directories, labels,
etc. That's because DOS uses 16 bits for allocation, and you can make
the chunks bigger but not have more of them.

  Extenders are useful when a single file must be > 32MB.
