Thread: FC3 boot question

  1. FC3 boot question

    To all, I have what I hope is a dumb question. This system is a intel P3
    800 with 512 ram, intel MB. When it boots it shows that it is booting to
    kernel 2.6.12-1.1381-FC3.this was the latest up2date had at the time.
    When it boots it comes up with kernel 2.6.9-1.667. Should I change
    grub.conf back to 2.6.9 because of the slower processor, or how can I
    get it to boot to the newer kernel? Do I even want to? Everything now is
    working fine.
    Thanks in advance for your advise and help

    As root with you choice of text editor edit the /boot/grub/grub.conf file,
    the default line. Remember the counting starts at zero (0).

    This is how I have changed it. It still boots to 2.6.9 kernel.Although
    I don't claim to be proficate at Linux I have been using it since RH
    5.0. Here is my grub.conf

    # grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You have a /boot partition. This means that
    # all kernel and initrd paths are relative to /boot/, eg.
    # root (hd0,0)
    # kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
    # initrd /initrd-version.img
    #boot=/dev/hda
    default=1
    timeout=5
    splashimage=(hd0,0)/grub/splash.xpm.gz
    #hiddenmenu
    title Fedora Core (2.6.12-1.1381_FC3)
    root (hd0,0)
    kernel /vmlinuz-2.6.12-1.1381_FC3 ro root=/dev/VolGroup00/LogVol00
    initrd /initrd-2.6.12-1.1381_FC3.img
    #title Fedora Core (2.6.12-1.1378_FC3)
    root (hd0,0)
    kernel /vmlinuz-2.6.12-1.1378_FC3 ro root=/dev/VolGroup00/LogVol00
    initrd /initrd-2.6.12-1.1378_FC3.img
    #title Fedora Core (2.6.12-1.1372_FC3)
    root (hd0,0)
    kernel /vmlinuz-2.6.12-1.1372_FC3 ro root=/dev/VolGroup00/LogVol00
    initrd /initrd-2.6.12-1.1372_FC3.img
    #title Fedora Core (2.6.9-1.667)
    root (hd0,0)
    kernel /vmlinuz-2.6.9-1.667 ro root=/dev/VolGroup00/LogVol00
    initrd /initrd-2.6.9-1.667.img
    title Win XP PRO
    rootnoverify (hd1,0)
    map (hd1) (hd0)
    map (hd0) (hd1)
    makeactive
    chainloader +1
    boot
    I hope this helps

    Of course, remove the '#' from each of the titles you added this to.

    If you do not want to boot to an older kernel then remove it;

    rpm -qa 'kernel*' ;provides a list of the kernels installed

    rpm -e kernel- ;removes the unwanted kernel, example;

    rpm -e kernel-2.6.12-1.1372_FC3 ;removes kernel-2.6.12-1.1372_FC3

    This will also remove the kernel boot choice from the grub.conf file.

    What you effectively have as your Linux boot choice;

    > initrd /initrd-2.6.9-1.667.img
