QNX does not boot if Graphics card is removed

Hello,

I have 6.2.1 PE running of a x86 based SBC - I had to plugin a PMC Video
Card to install QNX. Now that the ethernet and serial are working - I made
changes to the startup script so that I can login over the serial terminal
and/or through telnet or FTP.
Basically I do not need the Video card (and kbd/mouse) anymore - if I remove
the Video Card the boot does not complete (I have set the BIOS I/O
redirection to Serial as Always). When I removed this PMC Video Card - I get
the message
“Boot Partition 1 ? 1
Hit Esc for .altboot …”
and the booting process stops.

Once I get the SBC to boot without the PMC Video Card - my next step will be
to build an image that uses only Serial Port Console.

Is crttrap clear the way to start?

Any comments or questions - please let me know.

crttrap(and the file it generates) is only required if you start a graphic
driver which, I assume, you are not doing.

I thought crttrap clear will remove any reference to the driver, so that the
driver is not started.

Thank you

No, it’s to reset the graphics driver auto-detect system.

It sounds like you should build a custom boot. However, you may get success just by touch’ing /etc/system/config/nophoton
