Keep in mind that the Zorro III interface of the CV64/3D has some timing issues when really fast Zorro III busmasters (like the DENEB) are driving the bus. This can lead to bus errors and broken data transfers. A workaround is already present in the DENEB, so this is not a real problem, but one thing to keep in mind.
I have a Deneb too. I initially had problems with the DMA driver (corrupted data transfers to usb devices) but these problems were solved with your latest Deneb firmware update that has this workaround. thanks.
