Setup Utility program Attention: A customized setup configuration (other than default settings) might exist on the computer you are servicing. Running the Setup Utility pr ogram might alter those settings. Note the current configuration settings and verify that the settings ar e in place when service is complete.
Product Recovery Program menu T ype 2251/6830/6831 machines have recovery and diagnostics pr ograms on a separate hard drive partition. The Diagnostics diskette is not shipped with the machine or the HMM. T o download the diagnostics program, see “ Diagnostics download ” on page 10.
Diagnostics The diagnostic programs use a full range of diagnostic utilities to determine the operating condition of the computer ’ s hardwar e components. For a complete list of error codes and messages, see ″ Symptom-to-FRU Index ″ on page 39.
A selected test is marked by >> . Pressing the space bar again de-selects a test and removes the chevr on. 4. Repeat steps 2 and 3 above to select all desired tests. Module test menu/hardware configuration report Depending on the diagnostic version level you are using, the installed devices in the computer are verified in one of two ways.
v Memory T est-Quick The quick memory test will take about 20 seconds per MB of memory and will detect solid (stuck) memory failures only . Notes: Either level of memory testing can be performed on all memory or a single SIMM or DIMM socket. Only sockets containing a SIMM or DIMM can be selected for testing.
v ChkDigits: Contains a 2-digit check-digit value to ensure the following: – Diagnostics were r un on the specified date. – Diagnostics were r un on the specified IBM computer . – The diagnostic error code is r ecorded corr ectly . v T ext: Description of the error .
v Destroys all copies of the F A T T able on all partitions (both the master and backup). v Destroys the partition table. v Provides messages that warn the user that this is a non-r ecoverable process. The Full Erase Hard Drive pr ovides a DOS utility that performs the following steps.
When to use the Low-Level Format program Notes: 1. The low-level format is not available on all diagnostic diskettes. 2. Before formatting the har d disk drive, make a backup copy of the files on the drive to be formatted.

Safety Information This section contains the safety information with which you need to be familiar , before you service an IBM computer . General Safety Follow these rules to ensur e general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
Observe the following rules when working on electrical equipment. v Find the room emer gency power-of f (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly .
v Do not service the following parts (or similar units) with the power on when they are r emoved from their normal operating places in a machine. This practice ensures corr ect grounding of the units.
Safety inspection guide The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had requir ed safety items installed to protect users and service personnel fr om injury .
Problem determination tips Because there is a lar ge variety of hardwar e and software combinations that can be encountered, use the following information to assist you in pr oblem determination. v V erify any recent hardwar e changes. See “ Hardwar e considerations ” on page 134.
Adding adapters to the system When adapters are added to the system, an ar ea in memory has to be allocated to run its pr ograms. This can be done with either hardware switches or software mapping . If there is a conflict in softwar e mapping, then the following may be true.
Not all device drivers are found in the CONFIG.SYS file. Advanced operating systems use .INI files to set up and start devices. Device drivers can access the hardwar e in five ways.
v POST Beep codes are sounds emitted fr om the speaker if the POST finds a problem. One beep indicates that the POST completed successfully . Multiple beeps indicate a problem was found. v Diagnostic error messages are displayed when a test pr ogram finds a problem with a hardwar e component.
ROM and RAM Addresses Adapter cards with pr ocessors can contain RAM and ROM. If the adapter cards have onboard memory , then the following are true. v ROM contains operating instructions for the adapter I/O. v RAM is used for buffering. T wo adapters using the same memory area will cause a failure.
