Was the original Lions book different to the officially published version I picked up on Amazon? Mine explicitly doesn't include hardware drivers, eg. for the RK disk packs, other than a sample driver, with a comment (presumably from Lions) basically saying that such things weren't as interesting. It also doesn't include much (if any? has been a while since I looked at it) userland source code. It is still a wonderful, educational book, though. John
