I am trying to install QNX 6.5.0 on a DELL PRECISION - T3500 machine. The network card BCM5761 connected was not detected then. Now I tried connecting an AMP network card. But now the card was detected in the Devices tab of Configure->Network. But still the network connection was not ok. So I decided to reinstall the OS. Now on booting, it ends up in a display setup menu. But I couldn’t move further after that. I tried to enter safe mode with no photon. But when the login prompt appears, the USB keyboard is not working. Please suggest a solution for my problem. I need a full working QNX setup with any of the above network cards working and network connection up. Also please tell if there is any way to edit any system files if needed to recover the installation. I am blocked in this issue. I need to perform some urgent testing in this machine.
