Multiple OS one machine hda: hda1: windows, hda2: freeBSD, hda3: fat32 (emply), hda5: secundary on 4 Swap, Slackware Fedora more Linux, fdisk report up to 15 partitions, my configuration is ...

hda: 1 (win xp), 2 (freeBSD), 3 (DOS fat32 empty), 4 Extended < 5 first ( linux OS all on / ), 6 ( second Linux OS on 7), .... 8, 9. 10. 12 > 
hda2: freeBSD < BSD:  12 ( 12 linux, 13, 14, 15, 16> .

now either GRUB or LILO can boot up to 5 OS either way, OS 6+ dont boot with various KERNEL  PANIC errors at the end, then try MBR on hda12 ( SLACK) and try add more then 4 OS and nothing, soo ... fi i fdisk /mbr, fdisk (create) hda1 , hda2, hda3, hda4 (extended), then create 7,8,9,19,11,12,13,14,15 and install every one in it (with out any SWAP), say 12 OS on it.

Whats the steps to create a multiple operating systems on one computer??
 thanks.
