I've recently been told that I will have to get bios revision 1009 in order to run an AMD FX8350 Black Edition 8 Core Processor on an Asus Sabertooth 990FX R2.0 Motherboard, and that I could do it from a memory stick before the two were fitted together.
I was just wondering if someone could tell me where to find the revision, and how I would go about installing it?
Thanks in advance for any help.
