The problem is with all boards that use the Aladdin V Rev. G or H, not just yours. You can mitigate it by using a non-plus CPU (the K6-III should work, and still has integrated L2), or just go with an MVP3 board (which I've heard are more stable anyway).

The K5 would work, but later DOS games might tax it. Remember they rated it against a Pentium Classic of the given speed (discounting any PR bullshit number fudging), and non-Intel x86 chips had pretty garbage FPUs until the Athlon. I'm sure someone around here has benchmarks, but I guarantee you the numbers won't be pretty, especially if you're gunning for late DOS 3D games. A K6-2 would be the easiest solution with your current equipment.

Alternately, get a Pentium MMX-233, drop the multi to 2.5x, and run it on a 100MHz bus. That sucker will scream. You could try for 3x if you're feeling spicy, but you need good cooling and an exceptional CPU.

Agree with Rawrl, pick a 200/233 MHz Pentium MMX for DOS stuff. You don't need K6 III for that.
