Has anyone in netland ever heard of or actually successfully used a DRV11 parallel i/f with a uVaxII? We are running 32m Ultrix version 1.1 on an uVaxII and the board is not being recognized. Examination of the csr register results in "illegal address". However, examination of the csr of the same board on other Q22 bus machines (excluding uVaxII's) is successful. Is there something specific to the uVaxII that is obstructing recognition of the DRV11? -- Tom Jones ...!uwmacc!sal70!jones

We presently are trying to get a driver for a dr11(unibus) running on the uvax. It drops right in the kernal and seems to work - I have not gotten everything working but that most likely due to my extreme lack of knowledge on the subject of referencing drivers from programs. I would be glad to share names & experiences if you want to call.
