Appendix B. Updating System Programs
The following contains information about updating system programs (POST/BIOS)
and how to recover from a POST/BIOS update failure.
System programs
System programs are the basic layer of software that is built into your computer. They
include the power-on self-test (POST), the basic input/output system (BIOS) code,
and the BIOS Setup Utility program. POST is a set of tests and procedures that is
performed each time you turn on your computer. BIOS is a layer of software that
translates instructions from other layers of software into electrical signals that the
computer hardware can understand. You can use the BIOS Setup Utility program to
view and change the configuration and setup of your computer.
Your computer system board has a module called electrically erasable programmable
read-only memory (EEPROM, also referred to as flash memory). You can easily update
POST, BIOS, and the BIOS Setup Utility program by starting your computer using a
flash update diskette.
IBM might make changes and enhancements to the system programs. When updates
are released, they are available as downloadable files on the World Wide Web (see the
Quick Reference). Instructions for using the system program updates are available in a
README file that is included in the update files.
To update system programs (flash the EEPROM):
1. Insert a system program update (flash) diskette into the diskette drive (drive A) in
your computer. System program updates are available at
http://www.ibm.com/pc/support/ on the World Wide Web.
2. Turn on the computer. If it is on already, you must turn it off and back on again.
The update begins.
Recovering from a POST/BIOS update failure
If power to your computer is interrupted while POST/BIOS is being updated (flash
update), your computer might not restart correctly. If this happens, perform the
following procedure to recover:
1. Using another computer and a text editor, open the config.sys file on the BIOS
flash diskette.
2. Find line:
shell = phlash16.exe /S
3. Change this line to:
shell = phlash16.exe
4. Save this file to the diskette. Now you can use this BIOS flash diskette to update
your computer.
5. Turn off the computer and any attached devices, such as printers, monitors, and
external drives.
6. Unplug all power cords from electrical outlets, and remove the cover. See
“Removing the cover” on page 15.
