Actually I've just managed to update my H310 card to latest A10 firmware using this guide which has a download link to all necessary files in one handy zip. :) Edit:  darn looks like I'm not allowed to post links, so just do a google for "revert your Perc H310 back to it's Dell firmware" and you'll find the right WordPress blog.     
As the title says I can't update my H310 raid card with this firmware: Dell PERC H310 Adapter Firmware release 20.13.2-0006  If im using windows it says that my system is not supported and using Linux it just just spits out this;  0  and then nothing else happens. I've tried several different computers and with discs attached and not attached to the controller.
