Removing extra kernels


After I upgraded from RH9 to FC1 I have a few extra boot options that I never use.

Here is grub.conf:

Code:
# 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 (hd0,1)
#          kernel /vmlinuz-version ro root=/dev/hda3
#          initrd /initrd-version.img
#boot=/dev/hda
default=2
timeout=10
splashimage=(hd0,1)/grub/splash.xpm.gz
title Fedora Core (2.4.22-1.2115.nptlsmp)
        root (hd0,1)
        kernel /vmlinuz-2.4.22-1.2115.nptlsmp ro root=LABEL=/ hdd=ide-scsi
        initrd /initrd-2.4.22-1.2115.nptlsmp.img
title Fedora Core (2.4.22-1.2115.nptlBOOT)
        root (hd0,1)
        kernel /vmlinuz-2.4.22-1.2115.nptlBOOT ro root=LABEL=/ hdd=ide-scsi
        initrd /initrd-2.4.22-1.2115.nptlBOOT.img
title Fedora Core (2.4.22-1.2115.nptl)
        root (hd0,1)
        kernel /vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdd=ide-scsi
        initrd /initrd-2.4.22-1.2115.nptl.img
title WinXP
        rootnoverify (hd0,0)
        chainloader +1


Here is the contents of /boot/

Code:
[mark@localhost boot]$ ls
boot.b                             os2_d.b
chain.b                            System.map *this is light blue coloured*

module-info *white on red background*
note: *comments* added by me,
Which parts can I safely delete, my system has only one cpu and RAM is 768mb.

Thank you

I like to use rpm to remove extra kernels, since it will clean up the grub entry automatically.

Run this to see what kernels are known to rpm:
$ rpm -q kernel

You can remove what you don't need (like the SMP version) like so:
$ sudo rpm -e kernel-2.4.22-1.2115.nptlsmp

The SMP version is used by multiple CPUs (and also hyper-threaded P4s I think).
It should be fine to remove the BOOT version also.

[BTW chefmark - you are running an ancient kernel. Today FC1 is up to kernel-2.4.22-1.2179.nptl.]
