Hello, We are attempting to configure a Microvax II as the hub of a wide area network. It had been our intention to put several DMV-11 controllers on the machine. They would each speak to a DMR-11 controller on a vax at the remote end. I have two DMV's working well on the Microvax now. The system is running 2.0 Ultrix. The trouble comes about when I attempt to configure the third controller into the system. At boot time if three controllers are ifconfiged in the rc.local, the system will hang when it ifconfigs the third device. If I attempt to bring the system up with the two working DMV's, then ifconfig the third manually, I get a message;'dmv0: can't initialize'. DEC support tells me that the 'can't initialize' message indicates that the system is trying to run an allocation routine on the bus and is unable to find enough resources to successfully configure all the devices installed. The bus contains the following devices: ------ CPU ----- My questions are: ---8 MEG MEM --- 1) Is anyone out there running with a ---8 MEG MEM --- config even close to this? Anyone able --- DEQUNA ----- get more than two DMV controllers on a ---- DMV ------- Qbus? -----DMV ------- 2) Does BSD 4.(2/3) support the DMV ---- DMV ------- controller? -----open ------ 3) Is there anyone familiar with the driver (next bus box) for this device? Am I correct in ---open--------- thinking that the device driver is where ---open--------- the device claims its share of bus ---open--------- resources? Is it a possibility to hack -----TK50------- driver to allow several controllers to ----open-------- coexist on the same bus? ----open-------- Thanks for any information...
