I am using (commercial) system commander. I think unlike bootmanagers, system commander can change bootfiles within same partition. Running 3 win98 se partitions, + on 1st partition also dos 6.22 & 5.0 (multiple configurations. It was very useful at old times when had a multiple config.sys/autoexec.bat + diffeent dos version for gaming. and never gave up since, lot easier to keeps of dad's partition by having kid's their own win98se install. As usual, system commander can also change partition parameter to "hide" partition type.
