It sounds like you corrupted something. If you replace this kernel with the original kernel, will it boot? If so, than it's something about the way the kernel was built. Greg, did you include UMSDOS support? Ann is using Zipspeak, and must have that to boot! What about PCI support? Like I said, check the obvious. If the old kernel won't boot, then something got corrupted. In that case, a reinstall may be needed, but let's hope not!
