Dúvida besta do Grub

Galera, meu grub.conf esta assim:

Quando inicio o micro, ele da o boot com o kernel 2.4.20-8 e gostaria que o boot padrão fosse o kernel 2.4.20-35_39.rh9.at. O defaul esta igual a 1 mas não entendi como mudar para dar boot com o kernel 2.4.20-35_39.rh9.at. Alguém sabe como fazer isso?

default=0

Valeu cara..
