Hi. 

For testing the RXV21 controllers, I want to peek and poke the
controller CSR to issue commands to the controller (seek, data transfer
via DMA, format, ...). But as I know the QBus bridge needs to be set up
bevore this can be done. I saw things like
D/P/L 20088004 80000001
or
d/p/l 20088000 80000000
d/p/l 20088004 80000001
What does this? What do I need to enable the QBus? How can I do DMA
transfers by hand?
