To elaborate on the title, I needed to fully reprogram the ROM chip on an Asrock 990FX Extreme4 because all firmware versions after 1.80 are garbage. I knew I would need to re-flash the GUID for the 1394 but what I didn’t realise before erasing the ROM chip and reprogramming it with my programmer is that I’ve lost my copy of fwguid, aka, 1394.zip, does anyone have a copy of this utility? Thanks peeps 
EDIT: I found a copy, uploaded here for an up to date source as this is not an easy piece of software to find.
1394.zip (1.1 MB)
