Working grub.conf for dual boot (CentOS 5 and Windows XP Home):

# 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 (hd0,2)
#          kernel /vmlinuz-version ro root=/dev/hda6
#          initrd /initrd-version.img
#boot=/dev/hda

with the following partition table (both Windoze and Linux on the same 
disk):

[dave at spindle ~]# sudo fdisk -l /dev/hda
