System hangs at hardware configuration screen

SCO OpenServer Handbook
Chapter 3, Troubleshooting the installation

When you start the installation from the Boot Disk, the system displays information about your hardware configuration, followed by a series of diagnostic messages. These messages display quickly and overwrite each other, so they are not generally visible, although the process normally pauses for a while at certain points if lengthy checks or initialization are involved. If the process stops and does not continue, this usually indicates a problem with the initialization of the corresponding device driver. The startup messages are described in Appendix G, ``Kernel initialization check letters''.

If your system hangs at this point, the problem might be an improperly installed adapter as described in ``Hardware self-check stops'', or it might be an I/O address conflict.

Check the hardware configuration screen; each line in the ``address'' column must be unique.
If there are no I/O address conflicts, run hardware diagnostics as explained in your computer manual and correct any identified problems.

Start the installation procedure again from the beginning. You can restart the installation completely at any time by inserting the Boot Disk, then pressing <Enter> at the Boot: prompt. If you are using the BTLD utility and need to restart, insert the Boot Disk and enter restart link=pkg1 at the Boot: prompt (where pkg1 is the name of the package from which to extract the required BTLD drivers). For more information, see ``Adding BTLDs at boot time''.

If the system hangs at the hardware configuration screen again, contact your software supplier for more information and be prepared to report the last message displayed.
