MPE/iX System Utilities Reference Manual (32650-90882)

20 SAINT
The Standalone Initialization Utility (SAINT) is an interactive utility program that
analyzes system libraries (which contain system object modules, or SOMs) to produce
executable images known as
boot images . A bootable image is a file that can be copied
directly to memory and executed without modification. The SAINT utility's primary
function is to produce a boot image for the operating system.
The input file upon which the SAINT utility is primarily dependent is the system library
file. The format of the library file is defined in the SOM Architecture Control Document.
WARNING Do not use this utility without service center support. Unauthorized
use will void your warranty and may cause data loss.
The following terms are used in this chapter:
CME Compatibility mode environment. This file contains the environment
required to run a compatibility mode program file created by the MPE
segmenter.
IODC I/O-dependent code. This I/O-device-specific code tests and accesses I/O
devices, particularly the boot device device (system disk).
IPL Initial program load. This is the first code to be executed from outside the
SPU. It is usually code residing on the system disk (the boot device) and is
brought into the system by the PDC and IODC code. It provides a user
interface to boot image or SOM files into the system to be executed.
LIF Logical interchange format. This is a common format used to identify the
contents of diverse media.
LST Library symbol table. This symbol table is contained in SOM library files
and defines the meaning and location of symbols contained in the SOMs
that are part of the system library file. The library file is defined in the
SOM
Architecture
Control Document
.
PIT Page information table. This table contains entries identical to the page
table entries required by the system architecture. These entries describe
the physical page layout of the bootable image contained in the boot image
file.
PDC Processor-dependent code. This code is contained in ROM and invokes
processor self-tests, locates the boot channel, and checks the condition of
the boot device path (including the CPU, main memory, and access to the
boot device).
