Doesnt really tell me what i need to know.

basicsally:was the p4 available in 400mhz,533mhz and 800 mhz.?
was the 800 mhz confined to presscott?
are all the p4 processors multiplies by 4 ie 200mhz x 4=800 mhz
133x 4=533 etc?

Yes there were 400mhz and 533mhz versions of the P4. The multiples would depend on the chip in question.

Here is intels spec sheet listing all processors, steppings and cores.

There was no 800mhz fsb prescott in 2.4. The only prescott core 2.4 was the 2.4a which has a bus of 533mhz. The 400mhz fsb was the willamette which is brutal for overclocking and the 2.4 Northwood at 800mhz fsb.
