Dear Johntorsteen,

Thank you for contacting ASRock.

Regarding your question, please follow the step to rewrite 1394 GUID.
1.     Please check the 1394 label in your motherboard and write it down. The 1394 GUID looks like 00138F00XXXXXXXX.
2.     Unzip the attached file "1394.zip" and save it to a bootable USB flash.
1394.zip download link: https://mega.nz/#!5sgDkKaD!9fPgyo6hDjncV0YxlszMpl98ZgU6Je8tAac0UX-vkKQ
3.     Reboot your system and boot into the USB flash with Hotkey <F11> during POST.
4.     Run the 1394 program and key in "fwguid c XXXXXXXXXXXXXXXX" then press enter. System will re-flash the 1394 automatically.

Thank you!
Yours truly,
ASRock TSD
