Any idea how to solve this problem? The updates do _what_? Rather than changing that entry in grub's list, find the section like this: ## ## Start Default Options ## ## default kernel options ## default kernel options for automagic boot options ## If you want special options for specifiv kernels use kopt_x_y_z ## where x.y.z is kernel version. Minor versions can be omitted. ## e.g. kopt=root=/dev/hda1 ro # kopt=root=/dev/ide/host0/bus0/target0/lun0/part5 ro and change that last line to be: (Assuming your 2.4 kernel is 2.4.27) # kopt=root=/dev/sda3 ro # kopt_2_4_27=root=/dev/hda3 ro and run update-grub. That should autogenerate the grub-used sections -- the ones without any '#' in front, after ## ## End Default Options ## And future 2.6 installs will get the right device (the sda one) and if you install any further 2.4 kernels you'll have to make another "# kopt_2_4_xx=root=/dev/hda3 ro" line and rerun update-grub. You can check the output in the lower section, and make sure it's generating sensible grub entries. The use labels for the rest of your data partitions, and... I dunno, put both /dev/hda3 and /dev/sda3 in your swap list? Let your 2.4 kernel boot without swap until you manually activate it? Solve to taste, and serve with a side of "I hope that helps". ^_^ Hmm. This assumes you're using update-grub and the Debian-supplied/ maintained grub/menu.lst. If not, then... well, don't lose your paddle. -- ----------------------------------------------------------- Paul "TBBle" Hampson, MCSE 8th year CompSci/Asian Studies student, ANU The Boss, Bubblesworth Pty Ltd (ABN: 51 095 284 361) Paul.Hampson@Anu.edu.au "No survivors?
