I just checked the pdf for that mobo. The 1394 bracket you have is of
the 1394"A" variety (aka: firewire 400), and is not pin for pin
compatible with the 1394"B" (firewire 800) header on the newer mobos.

In addition to the lower bandwidth, 1394A gets terminated to a 6 pin
connector, whereas firewire 800 is terminated to a 9 pin connector.


The 1394b cable assembly/L-bracket is available from Gigabyte's US
facility ($18US):
