I am in the process of installing WSE 2016 on a new HP ML10V2 and have one item in the device list that I cannot seem to find a driver for. I actually had two but was able to clear one of them by installing the ILO drivers from the HP site. The device in question is labeled "PCI Memory Controller" and shows up under "Other". Just to see if it was WSE 2016, I installed a fresh copy of WSE12R2 and had exactly the same situation. I configured the box with an HP hot swap drive cage (replacing the stock cage) and a P410 Smart Array controller (256MB w/ BBWC). I also installed the latest 2016 SPP but that made no difference. One thing I did was to disable the on board B120i SAS controller as I'm running all my drives off of the P410. I haven't seen any problems with this error but I would like to get it cleared at some point in time.
