[mod.computers.vax] qnverter II in a microVAX II

HANEWINK@DM0MPB51.BITNET.UUCP (02/27/87)

I have just made some tests with a QNVERTER II in a microVAX II.
 
1) No problems with noDMA drivers.
 
2) The microVAX II has no buffered data path.
   So Unibus-DMA drivers, which use REQDPR to request a buffered
   data path hang up the machine.
   The only thing to do is, to remove this statements or better set it
   conditionaly like in the DR11W(A) example in the I/O drivers manual.
