Short of a full reinstall, this is not easy to fix. (You could perhaps chose another geometry translation scheme in your BIOS, and fixup all the fdisk entries, but it's dangerous.) In case this started to happen with a custom kernel but your previous kernel used to boot (since it was incidentally all below cylinder 1024), boot this one, and backup what you need. Once the kernel has been fully loaded, the above is no longer a problem. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
