I don't know. But LILO can, of that I am certain, as I use it. (Standard
precompiled kernel with initrd)

Here are the relevant entries from my lilo.conf:


/dev/md0 is 2x78GB a raid1 array using /dev/hdb1 and /dev/hdc1.

The raid-extra-boot is the clincher here; it tells lilo these disks form
part of an array and BOTH need boot records.
