I've just done a bit of catchup on fd-dev and noticed that nobody in
this thread mentioned partition type 0x85, the Linux extended partition
container. The Linux kernel treats 0x05, 0x0F and 0x85 identically
allowing multiple extended partitions in the MBR and one extended and/or
upto four data partitions in each extended partition.

There only reason for the 0x85 partition to exist was that at the time
no M$ OS could access sectors beyond the CHS limits. (The bios extensions
didn't exist either) Nowadays putting an 0x85 in partition 1 is a good
way of protecting partitions from M$ corruption as M$ would never follow
Linux's lead ... :-)
