I have a HP DC7800 SFF (GC760AV), i recently changed the CPU and it now says "microcode update error" dureing post, i done some research and found i need to update the BIOs for the cpu to be compatible. My question is, how do i go about updateing the BIOs when there is no operating system, i know is possible as i have done it before and there is even an option in the BIOs to flash from a usb key or CD, yet i cant find anything on the internet that lets you flash the BIOs directly from the BIOs, the last thing i want to do it install an OS, just to update the BIOs.
Any help and links are apreciated, Thanks in advance.

Did you clear the CMOS before you put the new processor in? If not, do that and then give it a try.
