Upon first boot, I was greeted by the message "1394 GUID are invalid in both CMOS and Flash! Press F1 to Resume" I've found some documentation of this online; most of the responses suggest flashing the BIOS in some form or fashion, or disabling the onboard 1394 (and possibly onboard Ethernet as well). However, I'm seen an additional symptom: pressing F1 does not seem to do anything. I've tried several different keyboards, including one fresh from the store.
Does anyone have any experience with what I could do to get things back on track? Or am I destined for a visit from the RMA fairy?

USB keyboards? If so try ps2, sometimes things will not work properly until all drivers are installed.
I have a similar problem. My mobo is ASRock X58 Extreme. The error message is the same but when I hit F1 it proceeds to boot up normally. I posted questions twice on ASRock's customer support but they never even acknowledged receiving my questions let alone reply. I've been going on like this for over an year. I flashed my BIOS many times (with every new BIOS release). The message never went away. I googled for answers many times but still haven't found anything substantial.
