Planning to use a Pentium MMX, pure DOS, AT form. Which of the following should I buy or ignore?

Soyo SY-5BT5 Pentium MMX 200MHz
TOMATO MOTHERBOARD 5DTXII-TC VER.2.03
Acorp 5tx29
ABit AB-PX5
DFI P5BTX/L (rev. B)

Thanks for helping me out!

Stability is my main priority, I need a no-fuzz rock-solid MB that just works on DOS supporting the Pentium MMX. (Yes, I know they are 30 years old)

I would go with the DFI P5BTX or Abit PX5.
Note that mainboards produced in this period are often affected by the "capacitor plague" and demand the VRM sections to get recapped for reestablishing stability.

The Abit PX5 allow you to change the multiplier and the FSB in the BIOS. That could help with speed sensitve DOS games.
