For example, suppose four (4) RQDX3 controllers, two (2) DELQA Ethernet controllers, and three (3) DHV11 controllers are needed. Note that when using a CHARON-VAX TMSCP controller it is seen by the VAX as a TQK50.

For the next step configure CHARON-VAX with only a console terminal. Start CHARON, wait until the ">>>" prompt is displayed, enter the "configure" command and enter you configuration followed by "exit":

...


Info
  1. Some QBUS devices are not able to set an interrupt vector. For such Devices, VMS sets the vector programmatically when initializing the device. For example, RQDX3 and DELQA/DEQNA
  2. The addresses above are 16-bit wide, but CHARON is able to understand 22-bit addresses. Therefore, it is necessary to sign-extend them before writing into CFG file.
  3. Numbers are octal, so attach "0" in the beginning.


For

this

example,

the

configuration

file

would

be

as

follows:

load RQDX3/RQDX3 DUA address=017772150
load RQDX3/RQDX3 DUB address=017760334
load RQDX3/RQDX3 DUC address=017760340
load RQDX3/RQDX3 DUD address=017760344
load DELQA/DEQNA XQA address=017774440
load DELQA/DEQNA XQB address=017774460
load DHV11/DHV11 TXA address=017760500 vector=0320
load DHV11/DHV11 TXB address=017760520 vector=0330
load DHV11/DHV11 TXC address=017760540 vector=0340

Units must obviously be configured, but it is out of scope here.

Your copy of your VMS system may not automatically understand this configuration. It may be necessary to build a new VMS system from the original VMS media but if all the required elements are available in your VMS system, it may be possible to reconfigure by executing the following commands:


$ SET DEF SYS$UPDATE
$ AUTOGEN GETDATA REBOOT


This application note is provided for information only to assist customers in dealing with complex configurations. This functionality described is standard VAX and VAX/VMS functionality and is not covered by CHARON-VAX support contracts.
