System Programs System programs are the basic layer of software built into every IBM computer. They include the power-on self test (POST), the basic input/output system (BIOS) code, and the Configuration/Setup Utility program. POST is a set of tests and procedures performed every time you turn on your computer. The BIOS is a layer of software that translates instructions from other layers of software into electrical signals that the computer hardware can understand. In the past, the system programs were stored in a read-only memory (ROM) module on the system board. Generally, the contents of ROM modules cannot be modified after they have been originally programmed. However, a type of nonvolatile memory referred to as electrically erasable programmable ROM (EEPROM) can be reprogrammed while it is in the computer and has replaced the ROM module on the system board in ThinkPad computers. System programs are stored in a type of EEPROM module referred to as Flash memory. The contents of Flash memory can be easily updated with an update (Flash) diskette. The process of updating system programs is often referred to as "flashing the BIOS." As part of the continuing work to improve quality, IBM might make changes and enhancements to the system programs. When updates are released, they will be available on the World Wide Web (http://www.ibm.com/thinkpad). Instructions for using the system programs updates will be available in a README file included in the downloaded files. If an &dock. installed with IBM 100/10 EtherJet PCI Adapter with Wake on LAN or IBM Auto Wake Token Ring ISA Adapter is connected with your computer, the system programs also can be updated remotely when the computer is unattended. 134 IBM ThinkPad 380Z Online User's Guide

IBM computer.
They include the power-on self test (POST), the
basic input/output system (BIOS) code, and the
Configuration/Setup Utility program.
POST is a set of tests and

The BIOS is a layer of software that translates instructions from

In the past, the system programs were stored in a read-only
memory (ROM) module on the system board.
Generally, the
contents of ROM modules cannot be modified after they have
been originally programmed.
However, a type of nonvolatile
memory referred to as electrically erasable programmable ROM
(EEPROM) can be reprogrammed while it is in the computer and
has replaced the ROM module on the system board in ThinkPad
computers.
System programs are stored in a type of EEPROM
module referred to as Flash memory.
The contents of Flash
memory can be easily updated with an update (Flash) diskette.
The process of updating system programs is often referred to as
“flashing the BIOS.”
As part of the continuing work to improve quality, IBM might
make changes and enhancements to the system programs.
When updates are released, they will be available on the World
Instructions for using
the system programs updates will be available in a README file

If an &dock. installed with IBM 100/10 EtherJet PCI Adapter with
Wake on LAN or IBM Auto Wake Token Ring ISA Adapter is
connected with your computer, the system programs also can be
updated remotely when the computer is unattended.
