If POST detects a problem (more than one beep sounds), an error message appears on the screen. See "Beep symptoms" on page 99 and "POST error codes" on page 109 for more information. Small computer system interface (SCSI) messages (some models) If the computer has an Ultra320 SCSI adapter installed and you receive a SCSI error message, see "SCSI error codes" on page 112. Note: If the computer does not have a SCSI hard disk drive, ignore any message that indicates that the BIOS code is not installed. Diagnostic programs and error messages The system diagnostic programs are on a hidden partition on the hard disk. These programs are the primary method of testing the major components of the computer. You can also download the latest version of the diagnostic programs from http://www.ibm.com/pc/support/ and use the downloaded file to create an IBM Enhanced Diagnostics diskette. See "Downloading the diagnostics program" on page 19. When using diagnostics with a USB keyboard and mouse attached, complete the following steps to enable USB emulation through the Configuration/Setup Utility program: 1. Press F1. 2. Select Devices and I/O Ports, and press Enter. 3. Select USB Setup, and press Enter. 4. Make sure that the USB keyboard and mouse are enabled. Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing complex problems indicated by error messages should be performed by trained service personnel. Sometimes the first error to occur causes additional errors. In this case, the computer displays more than one error message. Always follow the suggested action instructions for the first error message that appears. See "Diagnostic error codes" on page 101 for a listing of diagnostic error codes. Text messages The diagnostic text message format is as follows: result test_specific_string Function Name: Result (test specific string) where: Result is one of the following results: Passed The test was completed without any errors. Failed The test detected an error. 18 IBM IntelliStation M Pro Types 6220 and 6230: Hardware Maintenance Manual
