Well, for starters, it's MacBidouille!
automated translations always make me cringe...
at least the first bit is correct. the following two should read:
----------------------------------------------------------------------------
Note that changing the bus from 133 to 166 Mhz would overclock the machine to more than 1 Ghz. To avoid this, you must reduce the multiplier from 6.5x to 6x
Watch out !!!!!
To ensure the stability of the machine after changes, it is imperative to have only DDR-SDRAM PC 2700! 2100 simms are to be avoided !!!
Changing the bus takes 2 steps:
1) changes to the motherboard
the photo is the underside of the motherboard.
I surrounded the three resistors in question.
They are in order R677, R678 and R676
For a bus of 133mhz: there is a resistor at each location
for a bus to 167MHz: you must remove R676
(It's about 100% on because I had 2:30 to scan both cards under the microscope and that's the only difference)
So there must be more to it (I have not taken the time to try and ram no longer lends itself to such practices)
Apple has added a second protection on Bi 867 cards: If you change the settings just on the motherboard, it will go to 167 Mhz only if you install a 1Ghz or 1.25GHz bipro card.
(So I'll turn it back to Amber:)
So on the daughterboard pictured, there is a series of three resistors,
numbered as follows.
167 Mhz Bus:
R27 nothing
R22 nothing
R26 Resistor
133 Mhz Bus:
R27 nothing
R22 Resistor
R26 Resistor
So it is a security or a lock from Apple

I'll leave it to you to edit the original posts: I have no way to do this...
