IBM PC730/750 - General Checkout (Type 6876/6886)

Applicable to: World-Wide

General Checkout (Type 6876/6886):
This general checkout procedure is for Type 6876 and 6886 computers.

On Type 6876 and 6886 Micro Channel computers, you can start the advanced diagnostics programs in one of three ways:
1. From the 700 Series 6876/6886 Reference Diskette
2. From the 700 Series 6876/6886 Diagnostics Diskette
3. From the System Partition.

From the Reference Diskette (Type 6876/6886):
The Reference Diskette is bootable. Starting the diagnostic programs from the Reference Diskette allows you to test the options installed in the computer or test the base system.

To Test Options (Type 6876/6886):

Notes:
1. Ensure that Rapid Resume is disabled before starting this procedure.
2. If Rapid Resume is displayed during this procedure, see ¿Running Rapid Resume Manager—.
3. Re-run the diagnostics tests.

To test the options installed in the computer, do the following.
1. Power-off the computer and all external devices.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Insert the Reference Diskette into drive A.
5. Power-on all external devices.
6. Power-on the computer.
7. Check for the following responses:
a. One beep
b. IBM Logo
c. Readable instructions or the Main Menu
8. If you received the correct responses, press Ctrl+A (Test the Computer screen appears). Select Options diagnostics and follow the instructions on the screen.
9. If you did not receive the correct responses, go to ¿Symptom-to-FRU Index—.

To test the base system, do the following:
1. Power-off the computer and all external devices.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Insert the Reference Diskette into drive A.
5. Power-on all external devices.
6. Power-on the computer.
7. Check for the following responses:
a. One beep
b. IBM Logo
c. Readable instructions or the Main Menu
8. If you received the correct responses, do the following.
a. Press Ctrl+A (Test the Computer screen appears).
b. Select System board diagnostics and follow the instructions on the screen.
c. When the QAPlus/PRO Main Menu appears, press Ctrl+A.
d. Select Diagnostics.
e. Select Module Test.

If the Module Test Menu is correct, run diagnostics.
If the Module Test Menu is not correct, go to ¿Module Test Menu and Hardware Configuration Report—.

9. If you did not receive the correct responses, go to ¿Symptom-to-FRU Index—.

From the Diagnostics Diskette (Type 6876/6886):

Important:
If the diagnostic program is started from the diagnostics diskette, you will not have the option to test the Micro Channel options installed in the computer.
The Diagnostics Diskette is bootable. The procedure for starting the Diagnostics Diskette when servicing Type 6876 and 6886 computers is the same as the Type 65XX and 68XX computer. See ¿General Checkout (Type 65XX/68XX)—.

From the System Partition (Type 6876/6886):
Starting the diagnostic programs from the System Partition gives you the option of testing the options installed in the computer or testing the base system.

To test the options installed in the computer, do the following.
1. Power-off the computer and all external devices.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Remove all media from the drives.
5. Power-on all external devices.
6. Power-on the computer.
7. Check for the following responses:
a. One Beep
b. IBM Logo
8. When the F1 prompt appears in the lower left-hand corner of the screen, press F1 (the IBM logo appears, then the System Programs Main Menu).
9. Press Ctrl+A
(Test the Computer screen appears).
10. If you received the correct responses, select Options and follow the instructions on the screen.
11. If you did not receive the correct responses, reinstall the System Partition on the hard disk drive from the Reference Diskette.

To Test the Base System (Type 6876/6886):

Notes:
1. Ensure that Rapid Resume is disabled before starting this procedure.
2. If Rapid Resume is displayed during this procedure, see ¿Running Rapid Resume Manager—.
3. Re-run the diagnostics tests.

To test the base system, do the following.
1. Power-off the computer and all external devices.
2. Check all cables and power cords.
3. Set all display controls to the middle position.
4. Remove all media from the drives.
5. Power-on all external devices.
6. Power-on the computer.
7. Check for the following responses:
a. One Beep
b. IBM Logo
8. When the F1 prompt appears in the lower left-hand corner of the screen, press F1 (a second IBM logo appears followed by the System Programs Main Menu).
9. If you received the correct responses, do the following:
a. Press Ctrl+A
(Test the Computer screen appears).
b. Select System board diagnostics and follow the instructions on the screen.
c. When the QAPlus/PRO Main Menu appears, press Ctrl+A
d. Select Diagnostics.
e. Select Module Test.
f. If the Module Test Menu is correct, run diagnostics.
g. If the Module Test Menu is not correct, go to ¿Module Test Menu and Hardware Configuration Report—.
10. If you did not receive the correct responses, reinstall the System Partition on the hard disk drive from the Reference Diskette.

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 6MB) 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.

From the Reference Diskette (Type 6876/6886):
To start the system programs from the Reference Diskette, do the following:
1. Power-off the computer.
2. Remove all media from the drives.
3. Insert the Reference Diskette into the primary diskette drive.
4. Power-on the computer.
After a few seconds, the IBM logo appears on the screen; then a second IBM logo screen appears, followed by the system programs main menu.

Power-on Password:
To service Type 65XX and 68XX computers with an active and unknown power-on password, power-off the computer and do the following:

Note:
On some models, this procedure will also remove the administrator password. See ¿Passwords— and ¿Riser Card (ISA) Administrator Password— for more information.

1. Unplug the power cord and remove the top cover.
2. Refer to ¿System Board Layouts— and locate the system board type you are servicing. Depending on the system board, the password is reset by a jumper or switch setting.
3. Move the password jumper to connect the center pin and the pin on the opposite end of the connector; or, change the switch setting as appropriate.
4. Power-on the computer. The system senses the change in the position and erases the password.
It is necessary to move the jumper back to the previous position and to reset the switch setting.
5. Remind the user to enter a new password when service is complete.

System Programs Main Menu (Type 6876/6886):
The following tables contain a listing of the System Programs Main Menu items followed by a description of the item.
