It works fine, it's more likely that it's 'NEM_HI.PRG' you're warned
against using.

Boot without the ToolKit-driver and reconfigure.

Some AB's won't even start in 40MHz. However, there are some things
you can do to improve stability:

1. Shield the underside of the AB with aluminium-foil.
2. Shield the wires from the GALs to the AB.
3. Replace the white wire from the Nemesis buffer to the DMA-chip with
   shielded wire.
4. You *have* done the resistor/inductor modificiation to the
   DMA-chip? (My AB wouldn't even boot until I did this)
