Software updated as well so now have the ET4000/W32i memory interleave checked and active.
With regards to the PicoGUS, the current PGUSINIT.PRG does not work with the latest v3.1.0 firmware. Complains about incorrect protocol. Unsure if this has been updated yet. In fact, with the latest PicoGUS firmware, the ScummST games do not work with the Soundblaster option set. I reverted the PicoGUS back to v2.2.0 firmware and ScummST games are happy again.
In other news, I have 2 x ET4000/W32 cards (note no i after the W32). Both do not seem to work in my Raven. Unsure if they should or not? I have not tried them since the above updates were done.
