I also have seen this problem using a WinSystems LBC-GX500. This is a Geode board.
It would eventually boot. I have felt like it to be a spec problem with-in the BIOS. The entire
spec for the CD drive might not be followed. This was true with a Micro-sys board.
You can only get official tech support from QNX by paying for it. However quite a few QNX people frequent this board and post answers to questions.
You didn’t describe much (hard drive, CPU, any installed boards etc) about your system or else I don’t recognize what it is from your description.
Assuming it has a BIOS, I’d try changing a few options. Especially if you have a SATA harddrive, you should enable legacy mode so it operates as an IDE device.
The behaviour your describing would seem to that starting drivers (typically looking for a harddrive) to interrogate for hardware is causing the computer to reboot.
I’ve also seen similar behavior on a PC104 board when the 5V power wasn’t quite up to spec (giving about 4.5V) and once the O/S started consuming CPU/powering USB devices it would overdraw the powersupply and reboot the board over and over again.
Thanks Tim. I think you made a good point about the legacy mode. Sorry for not describing the problem in depth.
I have an EBX board with VIA Eden C7 processor with 512 MB memory and Two SATA drive connectors and two PATA drive connectors (traditional IDE drives). I have tried combination of SATA/PATA but was not able to get it working. I do see an option for legacy/native mode in my BIOS. I will give a shot at it and see how far I can get. I did some research on qnx website and the closest thing that I found was “devb-ahci and devb-eide compete for the same bus, which results in a hang.” qnx.com/developers/docs/6.3. … es_booting
Hopefully the Legacy mode problem solves it for you.
Is your setup similar to the link you provided (built in CD-Rom in addition to the harddrive)? If the legacy mode thing doesn’t work, you might try unplugging the CD-Rom and using a USB CD-Rom to install the O/S to your harddrive.
Out of curiosity, is there a Hardware Health section in the BIOS on this board? If there is, check to make sure the voltages (12 and 5) are correct.
As I mentioned, I had some PC 104 boards that were slightly off (4.6V) that would do the same thing when trying to install the O/S. Once I correctly the power supply everything installed smoothly.
If that’s not a problem in your case then it means something else isn’t compatible with QNX on that board (you don’t have any ISA cards or anything plugged in do you?) that causes a re-boot when it’s interrogated by the O/S.
