Using the BIOS interface, you cannot read a sector that is on a cylinder above 1023, this means that if just one sector of the kernel you're trying to boot lies beyond cylinder 1023 as seen by the BIOS, you cannot load it. When you install FreeBSD the partition editor will warn you about this, in a rather subtle way I admit, if you look in the in the right hand column there will be a '>' if a partition extends past what the BIOS can cope with. But just because your filesystem extends past cylinder 1023 doesn't mean that your kernel is out there, it might be happy camping out down in the low cylinder numbers. makes more sense now ?
