This is a stock ART backup for the WNDR3700 v1. This comes in handy if you ever mess up your ART partition's data, thus rendering wireless permanently disabled (flashing firmwares will not help). Instructions on how to perform the ART reset (and make the partition writeable) can be found on http://wiki.openwrt.org/doc/howto/restore_art_partition. Apply the patch in this directory to your source tree to obtain firmwares with writeable ART partitions (applies to both v1 and v2 models of the WNDR3700).
