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. Chapter 3. Operating Your Personal Computer 27

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

Now,
the system programs are stored in an

As part of the continuing work to improve quality, IBM might make changes and

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.

Instructions for using the system programs updates will be available in a README

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
