commit 9a27dc4f9aab50d7c792f8c7a4acaa28a2e43acd
Author: Kevin Brace <kevinbr...@gmx.com>
Date: Thu Feb 23 19:59:29 2017 -0800
Version bumped to 0.5.184
This version fixes FIC CE260 / CE261 netbook integrated TMDS interface
(DVI) on / off. This fix also aids CX700 or later chipsets that have
the proper strapping resistor values set for DVI use. Another major bug
fix for OpenChrome DDX.

commit 1bfe1ad714051b6acc7fbc0af715371aa47f2d2b

Improvement in initializing integrated TMDS (DVI)
Had to add a special handling case in order to properly handle FIC CE260 /
CE261 netbook integrated TMDS interface (DVI) turn on / off. This fix aids
reinitialization when resuming from standby. FIC CE260 / CE261 were sold as
Everex CloudBook and Sylvania g netbook. This fix also aids CX700 or later
chipsets that have the proper strapping resistor values set for DVI use.
