mtd0 and mtd2 are the two BIOS drives. Unfortunately the BIOS
uses a proprietary flash translation layer from General Software,
which is not supported (the drives cannot be mounted). You can
create your own file system (jffs for example), but the BIOS
won't be able to boot from it.
mtd0 and mtd2 are the two BIOS drives, which use the resident
