Errors after flashing bios and clearing cmos

[DohboyIBM]

Hello everyone. I have run into some bios problems with an ASRock P45R2000-WiFi motherboard. I get 2 error messages on bios startup screen:
#1 ?1394 GUID are invalid in both CMOS and Flash!?
#2 ?MAC address are invalid in both CMOS and Flash!?.

When I got the board it did not boot with 4 gig of ddr2-1066. No Post and 3 short beeps then a pause. I borrowed 2 gig of drr2-800 from other my computer. It booted then with the 2 gigs and I installed window vista 64bit sp1. Figuring it had some sort memory compatibly problem I download the 1.4 bios update and installed using the windows utility from the asrock website. It flashed ok and restarted and I went in the bios setup page and loaded default setting. It restarted with no problems. Swapped the 4 gigs in it posted. I tried overclocking the fsb to 266 mhz but it didn't make it (got to about 230). The board didn?t post so I pulled cmos jumper and restarted that?s when I got the errors. I tried reflashing 1.4 but that didn?t help. I also tried the 1.3 bios but that didn?t work either. It shipped with bios 1.2. I should note that it still loads into windows at this point, I just have to press f1. The onboard nic doesn?t work right now as well.

Did I do something wrong here or is this board just defective? I followed the flashing instruction to the letter. Can I return a motherboard that I flashed to newegg? I think I?d rather get a different board at this at this point unless I can fix this one.

you overclocked the hardware, and screwed something up, clearing the cmos will not wipe out hardware damage. pricey lesson in why overclocking is not a good idea.

I don?t think it was the overclocking that killed it because I didn?t even raise the voltages up in the bios. I wasn?t even near the limit for P45 Chipset. Aren?t they able to handle what 500 MHz or more right? I was playing it safe, raising the FSB in 2 MHz steps. I had not raised the volts yet. I was aiming for 266 MHz so the ram be nice and happy at 1066 1:2 ratio and the CPU would be 2.9 GHz or so. I was able to get E4500 CPU to just over 3.0 GHz before on an Asus P5K Deluxe.

I guess you could say that the cause was overclocking because I would not of cleared the cmos if hadn?t push the FSB to point were the board wouldn?t post. If I had raise volt to something insane on the northbridge I would hands down agree with you.

My guess is that Windows based flash program overwrote something that didn?t affect it till I cleared the cmos. I would of used a Dos based flash program if had a working floppy drive (and floppy with no bad sectors) Are MAC addresses for onboard nics even saved in the bios? Anybody know? Or did I just fry some onboard components?

Pretty odd to hear someone say "overclocking is not a good idea" on an enthusiast forum.

First thing, did you save the original bios to a file during the first flash? If so, I would try to re-install it.

Here's something to try: MAC fix for Asrock

i had similar problem before. Please write to ASRock, they will provide you the tool to recover the MAC ID and 1394 ID.

Don't flash in windows, A usb flash/ thumb drive is the way to go w/o a floppy.

I have to agree. The only way to do any BIOS Flash is either a floppy or a thumb drive if the mobo supports it. I personally never do any changes like that while in Windows. Same for making a system Image. I only trust programs that do that in DOS mode ... Always works best that way.

I killed a commando w/ a windows flash.
