This is a short survey about QNX(http://qnx.com/) realtime OS related hardware features of the COMPAQ LTE Elite 4/75CX. For hardware details look at my Linux on the COMPAQ LTE Elite 4/75 CX.
I took the demo image from QNX(http://qnx.com) unzipped it to a floppy and could easily boot from it. Sorry I have forgotten to take a note about the version number. I guess it was 4.0.
Driver vga4 works only with 640x480 4-bit 16 colors.
Thought I tried different COM ports and IRQ IO combinations I couldn't get it to work.
