Paul, If you have access to a installation Linux, try this: 1 - start the installation as if you would reinstall from scratch 2 - somewhere in the installation, the installer will activate the dasds for you. as soon as it happens, drop to a shell (connect another session, and under sles or rhel you will have a shell awaiting you) 3 - mount your disks somewhere, /tmp/new for example... you will need to chroot into there... (more info on chrooting, see http://www.gentoo.org/proj/en/base/x86/chroot.xml. it's for gentoo but it's the same thing) 4 - cd /tmp/new && chroot . 5 - now you are in you old system. edit your config files to ensure everything is fine (/etc/fstab, /etc/modprobe.conf, etc) 6 - cd /boot and create a new initrd with mkinitrd 7 - run a zipl to recreate the boot record 8 - exit chroot, unmount the filesystem, reboot your system 9 - if your system still not boots, gave us some error messages... if boots, you owe me one cent... ;)
