You cannot have more than 4 PRIMARY partitions on a drive. The 4th
primary need not be an extended, nor need the extended be the 4th
primary. There are many disks around that have only one "primary" plus
the extended primary, which makes the extended the 2nd.

You can have no more than ONE active PRIMARY and still boot
DOS/windoze/OS2 successfully. Multiple primaries and DOS/windoze/OS2
boot failure used to be a common result of installing RedHat using Disk
Druid. With LILO on MBR, whether any or how many primaries are marked
active have no impact on booting Linux.
