I would be confused, I am heaving very hard time finding out what is going on in this tread.
Your situation:
You got a 900mhz Tbird, It is designed to run at 100mhz fsb with multiplier =9. Now you want to get a new 133mhz fsb board. With 9 x 133 you get 1197 mhz. This speed is perhaps desirable but not easy to get, Your cpu will need a lot of core voltage and serious cooling to get there, IF IT EVER WILL.
What you do is that you unlock the cpu multiplier with the pencil trick and use your new motherboards multiplier settings to compensate for the higher fsb speed.
You can run 7x133 = 931, or even try 7,5x 133 =998mhz (I know you will try that

). You can also play with the fsb settings for like 6,5-7x 140 or what ever.
Just remember that 900mhz in not a holy number for this cpu.
There is nothing more to it, simple as that
PS
Later you find out that you are becoming serious overclocker and you will start to gather better cooling and fans to reach the 9x133mhz }>
