98 needs to be first.
then XP
then pick a linux (but install its bootloader to its partition, not the mbr)
then install linux#2 and install the bootloader to the MBR.
I think that should work.
the most OS's ive ever had on one drive was 3. win95/win2k/mandrake.
better wait for some more info though, because im not certain that will work.
what exactly is the point of having them all anyways?
