That "200 FSB duron" is really a 100 MHz Duron, running at 200 DDR (or D
It's because the Duron is able to read info or 'data' on BOTH the rising and falling edge of a pulse...
The fastest Duron produced is the Duron 1800 Applebred, with L2 of 64 KB, running at 13.5x133MHz = 1800MHz
In the terms you are using, you would call this a '266 FSB duron' (2x133 = 266)
I think that a more understandable teminology would be to call this one a 133/266 MHz/FSB processor.
And yes, virtually any Socket A mobo ever made can run any 100/200 Duron ever made.
The only 200/400 MHz/FSB processor made by AMD is the Barton 3200+ which runs at 11.0x 200MHz = 2200MHz
