The following is the lilo.conf:
----------------------------------
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=5
message=/boot/message
linear
default=dos

image=/boot/vmlinuz-2.4.2-2
label=linux
read-only
root=/dev/hda7

other=/dev/hda1
optional
label=dos
-------------------------------------
But everytime I boot my machine, the defalt OS is linux.
What is the reason?
Thank you very much.
