Let's clarify that is a software RAID-5 (via MD). And I don't think people mean the master boot record (MBR), which can only go in cylinder 0 of the hard drive -- before any disk slicing. They mean you should make a separate /boot filesystem where the kernel and initrd go. > is this truly correct and if so, why? Because kernel and any initrd (which contain the software RAID support) must be loadable by the 16-bit Int13h Services. If the /boot directory is in a filesystem that is a software/OS stripe set (such as RAID-3/4/5/6/etc...), then 16-bit Int13h Services can't read it. > my experiences of putting the MBR on the /boot partition > are contrary to that it will even work and boot that way... Correct. I think they are referring to the kernel/initrd files in a separate /boot filesystem that is not software RAID (or only RAID-1/mirror). -- Bryan J.
