Instructions For "grub"

• For systems with "grub" as their boot loader, the config file is normally at /boot/grub/grub.conf
• An entry for our example kernel would look like this:

  title Red Hat Linux (2.4.20-8)
          root (hd0,0)
          kernel /boot/vmlinuz-2.4.20-8 ro root=/dev/hda1 hdc=ide-scsi
          initrd /boot/initrd-2.4.20-8.img

• The disks and partitions are numbered by bus numbers, rather then by letters: hd0,0 means /dev/hda1.
• If we have /boot on its own partitions, the path names should NOT contain /boot, and the "root" entry should point to the /boot partition.
• No need to run anything after updating the config file - grub will read it during system boot.
