cpu and bios upgrade help required

[Guest]

im attempting to upgrade my cpu, but i have a couple of questions that i hope someone can help me with, firstly ive just run the CPU-Z programme and it say's my motherboard has KT233/333 chip set does that mean i can use a cpu with a 333fsb, if not will a 333fsb stepdown in a 266fsb motherboard, my motherboard manual states that it has a KT266A chipset so im a little confused,why is the CPU-Z programme saying the chip set is both 266 and 333. also ive downloaded the bios upgrade for my motherboard but do i install the bios upgrade then fit the cpu or do i fit the cpu then install the bios upgrade.
as you can tell my knowledge of these matter in NIL, so please be gentle with me,lol
many thanks in advance

Hmmmm.... strange ... How you found BIOS file for you motherboard with these informations ? It says nothing.

Open computer cas and look for Manufacturer and model name.

i already know the make and model number of my mother board, i have the manual and it say's the mother has a VIA KT 266 chipset, 133ddr.
but i have theCPU-Z application and that say my motherboard has a VIA KT266/333 chip set, wha twaould like to is what is correct the manual or the CPU-Z application?.
secondly would processor that has a 333fsb step down in a motherboard with a 266fsb, and ther work fine.
i hope ive explained things a little better this time

You have VIA KT266 chipset in 100%. I'm not sure that is A version - KT266A which was very similar to KT333 and that is propably why CPU-Z show you KT266/333. Download Everest Home :
