I have a z97e-itx/ac which I updated the bios to 2.10 from the Website. Now when I boot I get the error message "Intel MAC addresses are invalid in both CMOS and FLASH" I have tried flashing using the mac address tool When I reboot I still get the same error. I cannot read the full screen as it all seems to be to the left but it does not give the expected results from the instructions below. Any ideas?  Thanks |

I have to ask. Windows 98? It must run from a bootable USB stick per the instructions. Not from C, assuming C is a HDD? |

PS While you X'd out one MAC ID in the pic, you missed the other two shown  |

Hi, Windows 10, Sorry, Screenshot is from instructions on site. Have made bootable dos usb, booted of stick, ran the command: mac cd06099xxxxxx (xxxxxx being the rest of the mac address from sticker on motherboard. When I run all I get back is "LanInfo.LanDeviceCount=1" Should I be using the older version Lan Tool? Thanks |

Looks like the tool does not support my LAn. Ran the command using: mac ad06099xxxxxx (replacing c with a) Got the following: Intel i218V(0x15A1) #1 Invoke Vendor's Utillity: suppoert 'w', 'c' and 'l' function only! Unsupported |

Odd. There is an I218V flashing section in the archive. Contact Tech Support http://event.asrock.com/tsd.asp" rel="nofollow - HERE and ask of them. Maybe they need to address the current i218V section somehow. Keep us posted huh. |

Maybe oversight, maybe not. Yet this post and the one above it didn't use the correct format for calling it from the usb stick CD to the usb stick and issue mac c [Your MAC Id] <Enter key> |

The 2.10 UEFI for the Z97E-ITX/ac board is dated 6/29/16. So almost two and a half months old. This is the first thread about this problem I've ever seen. It seems odd IMO that we've never seen this issue until now. Sure, I could have missed some threads, but all of them? That is, if it is related to the UEFI 2.10 update. Any UEFI update should not change or rewrite the MAC addresses, so why did they apparently become corrupted? GerryBoy, what method did you use to update the UEFI to 2.10? Please don't try to run the UEFI 2.10 update you did again, until we know what method you used. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

tried again. My usb was my boot drive C: so nothing wrong with that. Looked at help files on usb. Instead of using the command "mac cxxxxxxxxxxxx", I used "mac w", this gives you the option then to input the mac address with a scanner or keyboard. When I keyed in my mac address D06099xxxxxx. I got an error saying not supported and there was a list of mac addresses with the first 6 digits listed that was supported. I noticed D06099xxxxxx was not in the list but D05099xxxxxx was. I tried again using the w(keyboard method) using D05099xxxxxx. It was successful this time. My eyesight must be starting to go  . I must have read the sticker on the motherboard wrong. I have not checked it again as there are a lot of cables in the way......Anyway it is sorted now. Thanks for your help and sorry for wasting your time. Thanks again....... |
