How to install VMware 5.5 and higher on HP BL460c G6
Have you tried doing this on more than one server? The reason I ask is that the 'vanilla' 5.5u2d ISO definitely works on a plain BL460c G6 because I've just installed it for this question on one of our old decommissioned blades. It had had the "2014 09" SPP firmware pack ran on it (2015 04) is out but I didn't bother with it but I can confirm it absolutely works without any extra drivers or whatever.
