I've never seen anything about how to make lilo work with RAID 5 or RAID
6, and I wouldn't try it with RAID 0. It works almost always with RAID 1
because the partition looks like an ordinary partition and filesystem. I
expect it would fail badly if there was a read error that RAID would have
It may be a bit pedantic, but at boot time, having two copies of a
partition to boot off of is very similar, but not exactly like having RAID
1. Once the kernel and initrd have been loaded, the options increase
dramatically. There are certainly some really annoying limitations to the
PC BIOS and I'm very glad that new generations of firmware are being
developed that will get past the current restrictions.
It's not what I know that counts.
It's what I can remember in time to use.
