Patch to lilo allowing raid 1 /boot

1999-09-13 Thread Andrew Speer
Hello, I have just joined this list, but have read through as many of the archives as I could about booting from a raid1 /boot partition. From what I have read someone has done it using "grub" (I dont know it), but not via lilo. If what I discuss below has already been done/discussed or is just
