Some of the weirdest things I've heard have to do with how finicky these boards can be about RAM selection. Buying the correct speed from one manufacturer has never been so important. I also remember reading about some cache limitations of certain chipsets (e.g., how much memory they will effectively cache), but I don't remember any of it. Others on this list or some web site will have the answer. > And how about DMA-22 and Ultra-DMA 33 IDE drives?

I've had no problems with my Ultra-DMA/33 IDE drives. (knock on wood) But I will warn that if you want to use another more mainstream OS (e.g., OS/2, Windows, even some UNIXes), beware that they may have problems recognizing the geometry of a large drive. OS/2 and Windows are especially funny, because while they both are able to use ridiculously large partitions (a la 512 GB), their setup programs will not... K.S.
