(Get the code!)
2113 in hex is 841, so the 0x4108 at bytes 0x206-0x207 (=518-519) could be a dereference (-2113 sectors from here) except that it should be 842 as those bytes are in the -1 sector, not the -2.
If so, then this is definitely a new ISW metadata format; I'd have to guess that the $GAFR is a new signature for it Note too that the first sector is totally blank, it appears to only need the last sector now in terms of bootstrapping.
I can whip up a generic probe based on this, but whats mostly likely to be accepted into the package.
