The Hijack kernel (if it's the most recent) is actually better / newer than the v2final kernel. No need to replace it.

But as Tony says, that's only a small piece of the v2final upgrade. Try the upgrade again, using the .upgrade wizard under win98 or newer.

Or if you have Linux, skip all that stuff, and use the ethernet upgrade tool I wrote -- much faster, and it avoids the buggy serial upgrader woes.

Cheers
