A: To stop the overlapping, one must turn off the "dos compatibility mode"
on fdisk. You do this by using the "c" option to toggle "dos compatibility
mode" off.
EXAMPLE:
lrep:# /sbin/fdisk
Using /dev/hda as default device!
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
p print the partition table
q quit without saving changes
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): c
DOS Compatibility flag is not set
