The System Hangs without any Error Messages This is probably a SCSI bus problem. Check the SCSI setup for errors. Make sure all the SCSI devices are seen on boot up. One symptom of a SCSI bus termination error is that some devices are not seen on boot up. Check for bad SCSI devices, bad SCSI connectors, bad termination, duplicate SCSI IDs. Serialization Fails Once you have verified that you have entered the correct serial number/activation key, check the permissions on the /tmp directory (l -d/tmp). The /tmp directory should have the following permissions: drwxrwxrwt. If the permissions differ, enter the following command: chmod 1777 /tmp. Section 2. Installation Guide Large Memory Access SCO UNIX 3.2v4.2, Open DeskTop 3.0, OpenServer 3.0, and MPX 3.0 are limited to 512 MB of physical memory (RAM). The system will ignore any memory above 512 MB. SCO OpenServer 5.0.0 and 5.0.2 can access 512 MB of physical memory (RAM) without any patches. The systems can access up to 4 GB of memory by installing the SCO Large Server Supplement. OpenServer 5.0.0 requires Large Server Supplement version 1.0.0. OpenServer 5.0.2 requires Large Server Supplement version 1.1.0. OpenServer 5.0.4, and later, supports 4 GB of memory without requiring patches. When installing OpenServer 5.0.0 or 5.0.2 on systems with more than 2048 MB (2 GB) of memory you will need to limit the memory search during the installation process. To limit the search add the following string to the boot line you use to start the system installation: mem=1m-1024m After the system is installed you can set the correct memory size in the file "/etc/default/boot". See the man page for "boot" for the syntax of this file. There is a defect in OpenServer 5.0.0 and 5.0.2 that causes the system to report a negative memory size on systems with more than 2 GB of memory. This defect does not appear to cause operational problems but it may cause problems for shell scripts that use the "memsize" command. SCSI Extended Translation Setting The SCSI extended translation setting for disks with a capacity larger than 1 GB should be set to 'disabled' for all versions of SCO UNIX, Open DeskTop, and OpenServer 3.0. For OpenServer 5.0.x you can use SCSI extended translation. (Run the EISA
