SCSI Problems Some common causes and solutions for SCSI device problems are listed in the following table. Table 4-10 Solutions for SCSI Problems Problem Possible Solution System will not boot from a SCSI drive. Be sure that drive cabling and jumpers are set correctly. To boot to a SCSI drive, the drive with the lowest SCSI number will be the boot drive. No two drives can have the same SCSI number. See Figures 6-3, 6-4, and 6-5 for instructions on selecting SCSI ID. Compaq Professional Workstation AP500 Maintenance and Service Guide 4-16 Diagnostic Tools Network Problems This section provides some common causes and solutions for network problems. However, the process of debugging network cabling is not discussed. Table 4-11 Solutions for Network Problems Problem Cause Solution System does not detect a network controller. 1. Possible driver problem 2. Possible failed network controller 1. Load latest version of Compaq Workstation SSD for Windows NT. 2. Replace the system board. System Setup utility reports unprogrammed EPROM. 1. The network controller is defective. 2. Network drivers are not loaded. 1. Replace the controller or the system board. 2. Boot the workstation without the network drivers. Using a system boot diskette, reconfigure the network controller. Diagnostics reports a failure. 1. The cable is not securely connected. 2. The cable is attached to the incorrect connector. 3. There is a problem with the cable or a device at the other end of the cable. 4. The network controller is defective. 5. Network controller interrupt or memory overlaps the interrupt or memory of an expansion board. 1. Be sure the cable is securely attached to the network connector and the other end of the cable is securely attached to the correct device. 2. Be sure the cable is attached to the correct connector. 3. Be sure the cable and device at the other end are operating correctly. 4. Replace the controller or the system board. 5. Run Computer Setup and modify the network controller memory value. Diagnostics passes, but the system does not communicate with the network. 1. Network drivers are not loaded, or driver parameters do not match current configuration. 2. The network controller is not configured for the workstation. 3. The network controller interrupt or memory overlaps the interrupt or memory of an expansion board. 1. Be sure the network drivers are loaded and the driver parameters match the configuration of the network controller. 2. Select the Network icon at the Control Panel. Reconfigure the driver if necessary, using the Network Setup found in the Control Center. 3. Run Computer Setup and modify the network controller memory value.

Compaq Professional Workstation AP500 Maintenance and Service Guide 4-18 Diagnostic Tools Audio Hardware Conflicts This section provides solutions to hardware conflicts. Hardware conflicts occur when two or more peripheral devices contend for the same signal lines or channels. Conflicts between the audio interface and another peripheral device may be because of the settings of the base I/O addresses, interrupts, or DMA channels. The audio interface typically has the following settings: ¦ Base I/O address 220H ¦ OPL III I/O address 388-38Bh ¦ Interrupt IRQ 5 ¦ 8-bit DMA Channel 1 and Channel 0 or 3 To resolve hardware conflicts: 1. Change the hardware settings of the audio card or the peripheral card in your system if the p...
