P4 multiplier question

[aconsola]

My first post here, I'm quite a newby to the P4 scene, I last overclocked when I got my new amd K6-2 400, so It's been a while. I tried wading though old posts, but couldn't find this specific bit of info.
I currently have a sony system with the asus P4b266lm MB and a p4 2.0
From what I can tell using a program to read the bios info(from esupport.com, any other good utils for doing this?), the board is rated to 2.4 ghz with the 400 fsb. Being a sony, of course, all the chip adjustments are locked in the bios.
I bought(it's in the mail) a 2.6 400fsb chip.
If the multiplier is locked within the chip, would it then follow that the chip will run at 2.6 even though the board is rated at 2.4 max since the frequency being fed into the chipwould be the same as it would for a 2.4?
I guess my question boils down to this, since the P4 multiplier is set and locked within the chip itself, what impact does the Motherboard have on setting the core speed?
Is my MB listed at 2400 max because that is all that was available at the time it was made, or am I missing something here?
Does the MB actually do the multiplying with the chip setting the factor, or does everything happen internal to the cpu?
I know I could slap the chip in and see what happens, but if it is unlikely to work I'd rather resell it while it is still unused in a sealed box then sell it as a used chip.
thanks,

A BIOS update would fix your 2.4Ghz max. Welcome to the forums.

in short, yes it all happens inside the cpu.

your mobo *should* run the new chip without any problems, other than maybe not identifying the cpu correctly at boot up.

if you want to overclock the chip using that mobo, check to see if there is a jumper to set the board to "jumper free mode" and hopefully unlock the cpu options in the bios.
otherwise, you may be able to use a programe called cpufsb or softfsb.
both of those programmes involve identifying the PLL chip (clockgen).
with any luck, you'll then have much higher fsb settings to choose from.

according to google, the PLL chip should be ICS 950209CF, which isn't supported by my version of softfsb.
