No. It has been some years since I hacked the Powerstack II. I only
remember that there was some limitation. Maybe there was IO space, but
only limited to a small address rage for PeeCee ISA bus style hardware
like com(4), lpt(4), pckbc(4), ...

Hmm. There was something with the on board RAM of esiop(4). I stumbled
over this on port-hp700. Maybe it is worth a try to forceable en- or
disable this. But I suspect this is the "PCI DMA does not work"
phenomenon.

In this case you got farer then I was ever.
