No SDRAM support for T-Bred "B"?

The problem is in the BIOS of your KK266+. You should have the most recent
BIOS (which still won't recognize the Tbred as a Tbred; just a "unknown
CPU"). However, the Tbred multiplier is re-mapped by the KK266+ BIOS.
I believe Wes, often on the NG, has his XP2100+ running in a KT133 chipset
MB (which the KK266 uses).

Unless I am mistaken Wes is running an Athlon Palomino on an Iwill
KK266. His site, very useful, discusses getting the KK266 aka KT133
to recognize the Palomino. To do that a BIOS update was necessary. I
have the KK266+ which uses the KT133A and recognizes Palominos without
any trouble or BIOS update. This link...

I've got a KT7-Raid board, but they're all about the same as long as they
have the same chipset, and it is a KT133 (non A). I've used both
Palomino's abd Tbreds's in it.

...describes the difficulty getting the KK266+ to recognize the .13
micron Athlon T-bred cores. I believe (altho not convinced) the
problem has to do with hardware, that the motherboard does need extra
capacitors to process the new voltages and boards like the MSI K7T
Turbo2 v.5 are modified to do it. You can RMA older boards to Iwill
for the conversion but Iwill is not offering this upgrade for their
KT133/A series boards.

When you plug an unlocked (Tbred) 2100+ or higher cpu into a KT133/A
board, it defaults the multiplier to 20x. A tbred B core will run at that
speed. A Tbred A core won't and you get the old black screen. If you've
got a 2100+ or 2200+ tbred A core cpu, you'll have to do some mods to get
it to work. Most are listed in CPU-Tbred info in link below. If, after
properly doing one of the mods, it still won't boot, then there's some
kind of board problem. I've heard of the cap mod for MSI's board, but
don't know what it really does. I have my doubts that it adds a default
1.60v setting. If it does, then shame on MSI.
