| 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.

# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/hda

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-<version_number> ;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;
