Operating System Software functional description

Mini sysgen In a mini sysgen, an existing operating system is modified in a way
that does not require new system file input or patching. For example,
an existing feature is deactivated or reactivated, or a specification is
changed that is independent of the operating system files.
Update sysgen In an update sysgen, an existing operating system is upgraded to
include new features or is replaced with a new version of the system.
During this process, some or all of the existing system files on the
system disks are replaced with new files; user files are not affected.
Full sysgen In a full sysgen, a new operating system is built on empty system
disks; that is, new or used disks that have been cleared and
formatted prior to sysgen.
Complete instructions for each of these sysgens are contained in the
Xerox DocuPrint 180 LPS System Generation Guide .
The UI Software consists of two 3.5-inch floppy diskettes (one
supports the system UI Software, and one supports the UI Dialog).
The Printer Software also consists of several 3.5-inch floppy
diskettes. Refer to the "System software functional description"
chapter for further information on the System UI Software, UI Dialog,
and Printer Software.
The DocuPrint 180 LPS OSS, or system controller, runs both
background and foreground processing. All Xerox LPS systems are
run by basically the same software. The OSS is delivered for
installation and sysgen on quarter-inch cartridge tapes. The major
utilities or "tasks" run by the system controller are shown in their
hierarchical relationships in the chart below.
Figure 4-1 illustrates the hierarchy of the major DocuPrint 180 LPS
processing tasks. Following the figure is an overview of each task.
