  • Page 8: Installed Devices List

    IBM PS/2 Model 95 XP 486 HMS Installed Devices List 2.0 Installed Devices List If an adapter or device is missing from the list, you might have one of the following conditions: The fixed disk drive (hard disk drive) (or Reference Diskette) does not contain the module of code required to support that device.
  • Page 9 IBM PS/2 Model 95 XP 486 HMS Device Type 2.1 Device Type Run Automatic Configuration (see "Running Automatic Configuration" in topic 1.0 before continuing) and determine which type of device, SCSI or non-SCSI, is missing from the Installed Devices List (in Advanced Diagnostics), then continue with the following steps.
  • Page 10 IBM PS/2 Model 95 XP 486 HMS SCSI Devices 2.2 SCSI Devices The adapter supporting the missing device may be defective. If more than one SCSI adapter is installed, isolate them one at a time. Power-off the system and disconnect any internal and external SCSI devices from the SCSI adapter (except the default hard disk drive).
  • Page 11 IBM PS/2 Model 95 XP 486 HMS Non-SCSI Devices 2.3 Non-SCSI Devices Replace the missing device. Note: If the number of diskette drives shown on the list is incorrect, an error can occur during the tests. Restart the system, select View Configuration from the Set Configuration menu and verify that the drive information is correct, then continue testing.

  • Page 12: Power-On Password

    IBM PS/2 Model 95 XP 486 HMS Power-On Password 3.0 Power-On Password To service a system with a power-on password: Move the system board jumper J16, to connect the center pin and the pin on the opposite end of the connector (see the figure on page 12.0).
