git://git.hasevolq.net/syslinux.git Split and expanded version of chain module is on the chaindev branch. The module is fully documented in doc/chain.txt I wasn't sure if to make one giant commit, or kept all the history as I was going - so I chose the latter. Tag 'chaindev-review' marks the commit. New feats since my last mail include options: mbrchs, hideall, bss, bs, warn (see doc/chain.txt for details). setbpb is a composite option now, adjusting fields basing on bpb detection. Lots of other misc changes and a few bugfixes. Branch disklib contains small patch I sent a few days ago.
