When I go into rescue mode I get, e.g.:
Your system is mounted under the /mnt/sysimage directory
Sh-3.00# df -l

rootfs 7163 4937 1817 74% /

My grub.conf (in /mnt/sysimage/boot/grub) is
# 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

# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda

Concerning disks - there is just one: a 160GB SATA hard drive. The BIOS
is currently set to boot floppy, CD, hard-drive; I've fiddled with
ordering etc, but makes now difference.
