that translates instructions from other layers of software into instructions that the
computer hardware can understand. The Configuration/Setup Utility program
enables you to view and change the configuration and setup of your computer.
In the past, the system programs were contained in a read-only memory (ROM)
module on the system board. If you wanted to update POST routines, BIOS
instructions, and the Configuration/Setup Utility program, you had to disassemble
the computer and replace modules, or you had to replace the system board. Now,
the system programs are stored in an EEPROM (electrically erasable programmable
read-only memory) module, which is also referred to as a flash memory. The contents
of an EEPROM module can be easily updated with an update (flash) diskette. The
process of updating the system programs EEPROM 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.pc.ibm.com/cdt/) or through the
PC Company Bulletin Board Service (see “Using Electronic Support Services” on
page 100) in files that can be downloaded onto a diskette. Updates on the Web site
or BBS will have the file name NFJTnnA.EXE, where nn is a release number.
Instructions for using the system programs updates will be available in a README
file included in the downloaded files. When updating system programs with a flash
diskette, note the following:
If you have set an administrator password, your computer will halt and request
the administrator password. The update process will not begin until you enter
the password.
If you have set an administrator password and enhanced security is enabled, the
system programs update will run only if you first perform a cold startup (the
computer is turned off and then turned on).
If your computer is connected to a network, the system programs also can be
updated remotely, using network-management software, such as IBM LANClient
Control Manager. For further information on this procedure, refer to “Update
POST/BIOS from Network” on page 55.
