- I am running Intel UNIX SYSVR4.0.3. I seem unable to talk to the Belltech
- ICC serial ports, even though the drivers look to be installed on startup.
- The last step of the boot process when the onboard code for the ICC board is
- supposed to be loaded, I get the error message "/dev/icc: device not found".
- There is a dev entry for the /dev/icc, as well as each of the 12 ports, with
- and without modem control. I believe this started when I installed a Boca
- SVGA card (with the ET4000 chip). Although I had not used the ICC ports
- before, I am sure the ICC code used to load correctly. The ICC cards expect
- to use IRQ10. Although I am not yet hanging on a network, I also have a net
- card strapped for IRQ2, that will be recognized as IRQ9.
-
- I would like to prophylactically disable the IRQ2 line on the video board.
- Although I have a pinout description, I am having trouble bringing
- everything completely into focus. My pinout shows IRQ9 as pin 7. That is
- the one I need to disable on the video card, right? How do I identify which
- side and end of the board to start counting from?
-
- If someone has other ideas, please share them with me. Thanks in advance.
