I don't recall ever seeing the word "Normal" in this regard. Is
it actually "No" ? Since you are talking about 6.0, do you have
the manual? If so, refer to page 57, fig 3.4, which shows the
"CREATING FILESYSTEMS" menu. Even if no manual, are we talking
about the same screen? The fourth column shows "No" for some
entries which means that they *won't* be formatted. You would
have to enter F6 for a selected partition to change it's format
status.

By the way, please be forwarned that once you allow YaST or
Linux fdisk to modify a disk that has been created by a Win/DOS
fdisk you must not ever go back to using the Win/DOS fdisk to
modify the partitions. Stick with Linux fdisk thereafter. The
same would apply to Partition Magic 4.0 (for those that are
interested), which is capable of creating/modifying Linux
partitions, but can't deal properly with partition tables that
were written with Linux fdisk. If you use PM 4.0, begin from
the Win/DOS created table *only* and then stay with PM 4.0;
don't use Linux fdisk thereafter if you expect to be able to use
PM 4.0 again. You should tell YaST to not modify or format any
partition that was created with PM 4.0, including the swap
aprtition.

The issue is that Linux fdisk chains partition table entries in
the order of creation of each partition, whereas Win/DOS fdisk
(more simply) always chains them in their physical order on the
drive. Letting Win/DOS fdisk modify a Linux fdisk partition
table can result in a recursivly chained (infinite) loop because
Win/DOS fdisk is unaware of the "legality" of chaining by
creation order. It would be much simpler (IMHO) if Linux fdisk
would just stick to the Win/DOS method - I don't see the benefit
of the Linux chaining scheme.
