There are a number of different ways to switch kernels, but fundamentally the idea is that very early in the boot process a small programme is run that chooses the kernel that will run - often offering the user the oppertunity to switch. The method that I suggest for your system is to use grub, though lilo would work equally well, and there are other options. First make sure grub is installed, it probably is. apt-get install grub Next make sure grub is used to boot your system, it probably already is. Note that the command below assumes that your system will try and boot off the first hard drive. If this is not the case, consult man grub-install grub-install hd0 Last, tell grub about your kernels update-grub This should list all the kernels found, and the first one listed will be the default kernel. When you reboot, it you do nothing, that kernel will be used, else you can select alternate kernels. You can inspect, and modify, what update-grub produces by editing /boot/grub/menu.lst Please be aware that although grub almost always works on modern hardware, this can be a delicate process. If your boot does not work, then it may be somewhat tricky for your to get your system running again. So be careful. And if you see stuff you don't understand, investigate it before rebooting. -- Horms -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
