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?
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.
It's an issue with the motherboard not with the keyboard.
The OP has an issue with keyboard! Your F1 works his does not. The error message relates to the onboard NIC and the MAC address. If you google it the fixes are disable and replace the onboard with pci NIC card to some downloads that I do not have a clue how works http://fullrshare.com/download/1394+GUID+invalid+in+boo...
