plz help me, what should I do

issue resolved
I rebuild the initial ramdisk with mkinitrd in the chrooted rescue file system.
# mount /dev/hda2 /mnt
# mount /dev/hda1 /mnt/boot
# mount --bind /dev /mnt/dev
# chroot /mnt
then
# mkinitrd
DONE

here i must add that, in this regard, redhat is smarter then suse . becuase several times I have moved the hddrives from machineX to machineY, and redhat systems have no prblm.. i.e target machine boot sucesfuly.
