Qnx6.3.0 installation problem(Press Esc for .altboot ...

When I install qnx6.3.0 from cdrom. It prompts that Press Esc for .altboot…D, Then the whole system dies. I don’t know what’s the meaning of ‘D’. It means that my harddisk has some problem?

It could be an incompatibility with the controller. Have you tried SP3?

I have solved it ,because the cdrom has some problem. :slight_smile:
