Here’s the write up I did a while back for the same issue with my Crimson. The SRAM chips are different manufacturers but it looks identical otherwise. Maybe this will help.

Fixing Crimson Dallas Chip

Edit: I see your question was in reference to what geoman did with his. I’ll leave this post in case anyone ends up with the same issue and needs to sort the Dallas on a Crimson or Professional IRIS.

Thanks, that's exactly what I was looking for!
