QNX (the new download) - video and serial ports

Hello,

I installed QNX and I like it.
However, I have 2 problems:

  1. I have on-board video that I don’t use (I use my Voodoo3 which
    contros my main display), yet my on-board is detected and it keeps
    photon from working. How do I keep it from loading drivers for my
    on-board video?
  2. How do I set up a jumpered hardware modem on COM2?

Either go into your BIOS setup, and see if there’s an option to
disable the onboard video, or, run ‘crttrap trap’ from the console,
then manually edit /etc/system/config/graphics-modes, and
remove any lines that do not contain “devg-banshee”.

  1. How do I set up a jumpered hardware modem on COM2?

Make sure it’s jumpered to the standard settings of base 2f8,
IRQ 3. Also, you might need to enter the system BIOS setup and
disable the built-in COM2 device.

I can’t disable the on-board video on this PC, there is no switch to.
Also, my modem is set for the default COM2 IRQ, yet all my computer
detects in QNX is /dev/ser1 when I boot. Is there any way to manually
load the serial driver with thses settings.

Hi Tim,

Usually, you should have either an option in your Bios to disable your
On-board video card or jumpers on your motherboard to do so. Look at your MB
manual. Then you will also have to remove configurations for your On-board
video card from the QNX init files. But the easiest way is to simply
re-install QNX… Otherwhise, go in /etc/system/config/graphics-modes and
remove lines used for your on-board video card.

OK. Did you try my second suggestion?

You can examine the parameters which the serial driver is currently
using, with ‘pidin arg’. You can kill the driver, using
‘slay devc-ser8250’, and restart it. Check out the devc-ser8250
help page for details.
