Confuse about FSAA 2*2 and 2*2(LOD bias)

[RedJacket]

The FSAA 2*2 and 2*2(LOD bias) in OGL properties confuses me..
Some nice explaination would be appreciated...thanks in advance
PS ..as for me didn't notice any difference while playing game
My spec:
AMD Duron600@950..Leadteck GForce MX..driver 6.50..DirertX7.0a..Win98SE

FSAA tends to make textures blurry, esp those in the distance.
The Level of Detail Bias makes textures less burry while in FSAA by sampling them at a higher detail(a bit slower)
