  1. How can I stop QNX from autodetecting my video all the time and
    placing it’s own lines in /ets/system/config/graphics-modes (and the
    other graphics file in that directory). I have an on-board video chip
    (that can’t be disabled), and a 3Dfx Voodoo3. The Voodoo3 is the main
    video, and the on-board ATI is unused. Yet every time I boot, it
    replaces my graphic setup and Photon crashes hard (can’t even use the
    off button). I change the file, and it works, but it is replaced on
    reboot.
  2. How do I start devc-ser8250 on startup? I have a internal modem that
    requires it to be run (with no options). It is on COM2.
    3)Also, what version of QNX is the free download? Does stuff designed
    for QNX 4.x run on this? How do you install tar.gz files (like bash
    from qnxstart.com)? Is there a command-line package tool? Is there
    other sources of QNX packages besides the two sources listed in the
    package manager? Does XPhoton compile most X apps OK?

I like this QNX, but I want to know how to fix these problems,

If you don’t want it to detect your ATI card, remove it’s device and vendor
id from the /etc/system/enum/devices/graphics file.

I tried that (deleting the whole ATI entry), and then crttrap detected
VGA only.
Can I set up good video settings and then delete
/etc/system/enum/devices/graphics? I can’t disable this on-board
video. Any other suggestions? I had the 3dfx entry in the file when I
tried this. Also, does anyone know how to make the system autoprobe
for COM2 on boot?

OK… the post the files. Don’t just delete them. Read what some of
the other folks having trouble are doing

Maybe, but you might want to try (as a very unsupported hail mary hack)
removing everything but the entry for the Voodoo3 card

Also, does anyone know how to make the system autoprobe for COM2 on boot?

It does probe for COM1 and COM2. Does `ls /dev’ show an entry
for ser1 and ser2?
