coppermine-T 

Hi Denniss, i'm the guy who submitted the edit for the coppermine-T that you reverted.  I can't guarantee ALL BX boards support coppermine-Ts, but there's no question at least the Abit BX-133 RAID does, so it's not accurate to say they are old-core-new-board only as is the impression in the current state.  Their last released BIOS notes explicitly list support for 1GHz Celerons which are definitely Coppermine-Ts:

Also, on this forum there's an excerpt from someone who's had communication from Abit re: coppermine-T support (you have to scroll down, no direct link):

i'm pasting it here:

I think the PIII 1200mhz you guys are seeing is not a Tualatin but a faster PIII called the CopperMine-T.

There is a post from RichieZZZZ there and he posted:

you need to read HOCP they e-mailed abit about it.

<< There is and has been confusion about what exactly Tualatin CPUs will work in as we stated earlier. It seems as if Tualatin CPUs are not backwards compatible with BX or i815 chipsets. When I posted this earlier I got this mail from Don Goff that pointed us to this link which we had posted a month or so ago that states this, "Supports Intel Coppermine T CPU." about their BIOS upgrade for the ABIT BX133 RAID board. Admittedly I am a bit confused about this too so we asked ABIT what exactly the deal is and here is their response. 

Kyle,

OK, I have it. It is the confusion about CopperMine CPU vs. CopperMine-T CPU vs. Tualatin CPU.

The CopperMine-T was the CPU that was the bridge between the CopperMine and Tualatin platforms. The CopperMine-T can work in BX boards, usually through a BIOS update. 

The Tualatin CPU has a different pinout and simply will not work in a BX board. I have confirmed this with our R&D; and FAE so have to believe that this time it is true.

Scott.
