it won't be 1934, but 1394, got a little bit of dyslexia there dont'cha?
Firewire or 1394 is easily distinguishable on the external connector by how it looks compared to USB. USB is usually flat and rectangular, and Firewire is more of an oval, or "wide" oval, and you can clearly see the pins on the inside.
Here's a photo for reference:
As for the internal headers, which is what I think your main question was about, is a little different.
USB connectors are usually blue, as you noted. They can also be white or black, depending on who makes the board.
Firewire headers are often orange / orangish red, and are placed further "back" on the motherboard. USB headers will typically be placed closer to the "front" of the board, near the front panel connectors and hard drive / SATA connectors.
Firewire will also be labeled either "Firewire" or "1394a" (the "a" standing for the interface standard).
As can be seen here:

Edit: Found a good image of your motherboard (ASUS P8P67) and there's no actual 1394 header on the board, but there IS a port on the back, which is on the "Red tower" and is the second connector UP from the mainboard between the top two USB ports and the bottom eSATA plug.
