System Programs (Type 6876/6886) The system programs are utility programs for Micro Channel computers that allow you to: Change the system configuration Set passwords Change the date and time Set power management features Test the computer The programs are installed in a special protected area of the hard disk drive called the System Partition. The System Partition appears on the FDISK and FDISKPM screens for DOS and OS/2, so that the partition can be deleted and the disk space (about 6 MB) can be used for other programs. Before you delete the System Partition, you must first use the Back up/Restore system programs option on the system programs Main Menu to make current copies of the Reference, Diagnostic, and QAPlus/PRO diskettes. Without the System Partition, you must use these diskettes to configure and diagnose the computer. If the computer was manufactured without a hard disk drive, the system programs were provided on three diskettes: Reference Diskette Diagnostics Diskette QAPlus/PRO for IBM Diskette Starting the System Programs (Type 6876/6886) You can start the system programs from the hard disk drive or from the Reference Diskette. If an error occurs during startup, the computer automatically starts the system programs to help you isolate and correct the problem. If you do not want the system programs to automatically start when an error occurs, change the Bypass System Programs on error setting in the system programs. From the Hard Disk Drive (Type 6876/6886) To start the system programs from the hard disk drive, do the following: 1. Remove all media from all the drives. 2. Power-off the computer; then, power it back on. (The IBM logo appears on the screen.) 3. When the F1 prompt appears, press F1. (A second IBM logo appears, followed by the system programs main menu.
