Hi,

I have a problem. I was programming the bios and now I get a message: "1394 GUID are invalid in boot CMOS and Flash".

I need a program to assign this number. The instruction is also appreciated.

Anyone able and help?

There are tools to rewrite the firewire MAC address, but they can give you the tool and instructions.
The MAC addrfess is often written, on the side of the last PCI or PCIE slot
