*No* bootloader supports any kind of RAID. All any bootloader knows how to do is read in the kernel and the initial ramdisk image from contiguous sectors, and start up the kernel. However, *if* you ensure that your whole /boot partition fits right within one half-stripe of the RAID0 layer (i.e. all on the same disk) then this won't matter (except you'll have some wasted space on the other disk). You can easily copy the /boot partition manually to the other device in the RAID1 layer, using dd. The motherboard will always boot from the same drive; then once the kernel is running, the RAID array will be recognised as such and maintained in sync with itself. Also, *don't* use a RAID1 for swap space: it impacts performance with little practical benefit. Use separate swap partitions from each drive (just to keep the partitioning schemes the same) instead. -- AJS delta echo bravo six four at earthshod dot co dot uk -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
