I'm glad I could help. If you want to clean up a little the method, you can automatically switch the choice in grub at poweroff : /etc/rc.local.shutdown : if [ `uname -r` = 2.6.27-lts ]; then sed -ie s/default\ 1/default\ 0/g /boot/grub/menu.lst else sed -ie s/default\ 0/default\ 1/g /boot/grub/menu.lst fi
and automatically reboot when the old kernel is loaded : /etc/rc.sysinit , after /boot is mounted : if [ `uname -r` = 2.6.27-lts ]; then reboot fi don't forget to : replace 0 by the item corresponding to your new kernel and 1 by the other. have only one blank space between default and 0/1 replace 2.6.27-lts by the result given by uname -r under your old kernel. 2010/4/11 Giacomo Bagnoli <[email protected]>: > On Sat, 2010-04-10 at 20:22 +0200, Xavier Hallade wrote: >> Hi, >> >> I found a trick in order to disable one of the card, maybe this could >> help someone to figure out how to do this in a better way. >> I boot first with a kernel < 2.6.30 like the kernel26-lts (2.6.27) of >> archlinux, and choose the card with the stamina-speed switch.
