+Note that EXTLINUX installs in the filesystem partition like a
+well-behaved bootloader :) Thus, it needs a master boot record in the
+partition table; the mbr.bin shipped with SYSLINUX should work well.
+To install it just do:
+
+ cat mbr.bin > /dev/XXX
+
+... where /dev/XXX is the appropriate master device, e.g. /dev/hda,
+and make sure the correct partition in set active.
+
+
+If you have multiple disks in a software RAID configuration, the
+preferred way to boot is:
+
+- Create a separate RAID-1 partition for /boot. Note that the Linux
+ RAID-1 driver can span as many disks as you wish.
+
+- Install the MBR on *each disk*, and mark the RAID-1 partition
+ active.
+
+- Run "extlinux /boot" to install extlinux. This will install it on
+ all the drives in the RAID-1 set, which means you can boot any
+ combination of drives in any order.
