Cannot install Neutrino 6.21 and 6.3 on IBM x series


I’m trying to install QNX Neutrino 6.21 on IBM eServer
x-345 and IBM eServer x-236. On IBM x-345, the installation
stops after showing ‘/dev/pci did not mount’. On IBM x-236:
it keeps rebooting during installation process; it never reach
the partition creation part; it reboot at different point
each time. The same behavior happens even though I use
the Safe Mode, disable enumeration, and disable all drivers.

Has anyone experienced the same problem? I appreciate
any help or advice?

Thank you very much in advance.
