Next, you need to tell Lilo to boot from the raid device. Edit /etc/lilo.conf on the raid device, and make sure you have at least these two options set to match your raid: # Specifies the boot device. This is where Lilo installs its boot # block. It can be either a partition, or the raw device, in which # case it installs in the MBR, and will overwrite the current MBR. # boot=/dev/md0 # Specifies the device that should be mounted as root. (`/') # root=/dev/md0 To make these options active, you have to run /sbin/lilo. You will need to chroot into your raid partition to do this. Also, it helps to make the proc file system available inside the chroot before you chroot into it. Finally, make sure your raid drivers are either built into the kernel, or the modules are present in the initial ram disk. The stock kernels contain raid drivers as modules, and if you want to use the stock kernels, you'll have to add them to the ramdisk. Let us know how it goes.
