Frontside Bus speed

I recently purchased an AMD 1.1 Gb unit with 256 KB of PC2100 DDR. Here are my questions:

When I check my "Default" Bios settings, they appear as follows:
CPU BRAND: AMD K7
CPU TYPE: ATHLON
CPU SPEED: 500 Mhz
CPU RATIO: 5

Why does the Bios default to 500 Mhz with a Ratio of 5?
What is the sense of having PC2100 DDR if my Bus speed is only 100 Mhz.

 
There are two kinds of TBirds; B and C. B has a 100FSB (200DDR) and C has a 133FSB (266DDR).

If you have a B TBird, your bios will detect that and set itself to 100FSB. Obviously, it's not autodetecting your CPU b/c it's reporting a 500MHz chip. Go into the bios and set it to "manual select", then set it to a 1100MHz CPU. What mobo is this on?
