Help installing OS3.9 on to a A4000D

[matthey]

The AmigaOS 3.9 (including BB2 update) "AmigaOS ROM Update" doesn't work with the WarpEngine. It's probably the new exec.library in the "AmigaOS ROM Update". I haven't heard of anyone getting around this problem.

I wouldn't trade in your WarpEngine for a 3640. You get much more and faster memory. I would upgrade it to a 40MHz 68040 though. You could try Piru's exec.library replacement and see if it works. You would need to use LoadModule instead of the AmigaOS 3.9 ROM update thing. You can split the "ROM Update" with Piru's Blizkick utility and LoadModule those updates (with fixes) too.

That's good news if the ROM update is actually installed. You should have version info in the Workbench as Thomas wrote...

Select "version/copyright" from the Workbench menu. If it says "ROM 3.9" in the title and both versions are 45, then yes, it's working with ROM update now.

If your ROM update is working fully then please post your hardware configuration.
