You could re-compile the kernel under FC-1 with aic7xxx in the kernel rather than a module. (I'm assuming FC-1 and FC-2 look for /boot in the same place. If not, copy or move the new kernel, initrd and System.map to the appropriate place.) Nb Are you sure you have the correct entries in /etc/grub.conf and /etc/fstab ? I'd replace any LABEL= by the actual device /dev/hda5 or whatever. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
