- You probably let it pick an interleave of three, which is what the AMI
- BIOS generally defaults to. I don't think the BIOS determines interleave
- intelligently; it just picks the lowest common denominator. I don't know
- of any exceptions to the fact that IDE drives always use 1:1 interleave.
- Perhaps some obscure ones use something else, but I bet your Fujitsu is
- being hampered by use of the wrong interleave.
