Troubleshooting the installation

Identifying the problem

If the system hangs mysteriously, either at boot time, during installation, or shortly thereafter, use these steps to isolate and identify the problem:

  1. Confirm that your hardware is listed as supported on the SCO Certified and Compatible Hardware (CHWP) web page. If it is not, we recommend that you use supported hardware.

  2. If possible, check a suspected component on another machine with the same configuration (under an SCO OpenServer system, not MS-DOS).

  3. If any third-party drivers are installed, such as those supplied with multiport cards, remove both the driver and the hardware that it controls, relink the kernel, and see if the problem persists.

  4. Make certain that your devices are recognized at boot time. Watch the boot display, use cat(C) or vi(C) to look at the /usr/adm/messages and /usr/adm/syslog files, or use the hwconfig(C) utility.

  5. Check for hardware conflicts between components, including DMA, interrupt vectors, and memory addresses. Check for documented incompatibilities or limitations in the SCO Certified and Compatible Hardware (CHWP) web page.

  6. If your machine has features such as shadow RAM or memory caching, disable them.

  7. If you have a DOS partition installed, verify that it follows the guidelines in the NeTraverse Merge documentation.

  8. If your hard disk has more than 1024 cylinders, you must follow the restrictions described in ``BIOS support for disks larger than 1024 cylinders''.

  9. If your video adapter is incorrectly installed, the system can also fail. Check the following:

  10. If you installed DOS on your hard disk, you may have a partition table that SCO OpenServer system software does not recognize. You must use DOS version 6.0 or earlier. The DOS partition must not have been created with Disk Manager.
