RAID mode changes the behaviour in the case of a disk failure.
Normally, on disk failure, syslinux prints an error message and stops.
In RAID mode, it returns to the BIOS with INT 18h, which with a properly
functioning BIOS will cause it to boot the next device in sequence. If
syslinux is used on a RAID-1 /boot, then this will attempt to boot the
next drive in the mirror set.
