Integration guide: Troubleshooting

Desktop board will not power up

  • Double check the power cable connection from the power supply to your AC power source.
  • Ensure you are using an ATX12V compliant power supply.
  • Ensure that the 2x2 power supply cable with the 4-pin connector is plugged into the 12 V processor core voltage connector located near the processor socket on the desktop board.
  • Check for external power switch on back of power supply. Ensure it is turned ON.
  • Remove and re-insert the Intel® Pentium® 4 or Celeron® processor, memory, and any add-in cards to make sure they are fully seated. Remove any non-essential hardware components and boot the system.
  • Disconnect all power and remove the CMOS battery. Wait 10 minutes, then re-install the battery, reconnect power, and boot the system.

You get a beep code and no video during boot
A sequence of short beeps after turning the power on may indicate that there was a problem during DDR SDRAM memory device detection. Check to ensure system memory is properly installed, and ensure the DDR SDRAM DIMMs you are using meet the specifications. Select from the links below to view the list of memory modules tested with your desktop board: Processor heat sink fan will not turn
Connect the processor's fan heatsink cable to the processor fan connector labeled CPU FAN.

Ensure that the 2x2 power supply cable with the 4-pin connector is plugged into the 12 V processor core voltage connector located near the processor socket on the desktop board.

Floppy drive or CD-ROM not detected during boot
If you make any hardware changes related to drives, such as adding/removing hard drives, floppy drives or CD-ROMs, the specified boot order may change.

Additionally, after you upgrade to a new BIOS or if you set the BIOS to factory defaults, your floppy drive or CD-ROM may not be detected in the desired boot order.

To re-specify the boot order in BIOS:

  1. Enter the BIOS Setup program by pressing the key after the Power-On-Self-Test (POST) memory test begins.
  2. Select the Boot menu and then the Boot Device Priority menu.
  3. Select 1st Boot Device, 2nd Boot Device, etc.
  4. Save and exit [F10].
BIOS recovery
If you are sure that you have integrated the PC components correctly but the system is not booting properly, letting you enter BIOS Setup, or reflash the BIOS, then you may need to perform a BIOS recovery. To do this:
  1. Place the latest BIOS revision on a bootable floppy disk
  2. Make sure the system power is off
  3. Ensure that you have known-good DDR SDRAM memory installed.
  4. Put the BIOS disk in the floppy disk drive.
  5. Remove the BIOS configuration jumper.
  6. Turn on the PC.
  7. Wait several minutes while the BIOS is reinstalled into the desktop board flash memory. There will not be any video during the BIOS recovery.
  8. After you hear two beeps and the floppy disk drive light turns off, remove the BIOS disk.
  9. Turn off the PC.
  10. Replace the BIOS configuration jumper.
  11. Turn the PC back on.
The following table illustrates the appropriate jumper settings:

Mode
 Jumper Position
 Function
Normal Pins 1-2 shorted Normal operation and changing standard BIOS options
Configure Pins 2-3 shorted Modify passwords, memory latencies, and IRQs
Recover Open The BIOS attempts to recover default BIOS configuration from a diskette. SPD system memory must be used to complete a BIOS recovery.

Caution Turn the power off before moving the configuration jumper.


Desktop board resources not recognized by Microsoft Windows*
Intel chipsets have several components that are newer and not necessarily enabled in the retail or OEM versions of Microsoft Windows* 98 SE, Microsoft Windows* Me, Microsoft Windows* 2000 or Microsoft Windows* XP. You may need to install the INF chipset update utility and additional drivers in order for all the board features to work properly. See the System Setup by Operating System section of this guide for assistance.

Enabling Ultra ATA/66/100 hard drive support
To get Ultra ATA/66/100 disk transfer support, ensure that the following conditions are met:
  • Use an Ultra ATA/66/100 capable hard drive.
  • Follow the cable installation instructions in the Assembly section of this integration guide.
  • Follow the instructions in the Windows 98 SE and ME Setup section of this integration guide to enable DMA transfers in the operating system.
  • If your hard drive comes with an ultra DMA driver or utility, make sure that you load it and enable Ultra ATA/66 (DMA mode 4) transfers.
Enabling dual channel memory
This section is applicable to the Intel Desktop Boards D875PBZ, D865GBF, D865GLC, and D865PERL only. These boards have four DIMM sockets arranged as DIMM 0 and DIMM 1 in both Channel A and Channel B.

To achieve dual channel operation, install a matched pair of DIMMs (equal in speed: 266MHz PC2100, 333MHz PC2700, or 400MHz PC3200; density: 64 MB, 128 MB, 256 MB, 512 MB, or 1 GB; and technology: 128 Mb, 256 Mb, or 512 Mb) in DIMM 0 in both Channels A and B. If additional memory is to be used, then install another matched pair of DIMMs in DIMM 1 in both Channels A and B.

DIMM Installation
Figure 2: DIMM Installation


Notes
  • All other memory configurations will result in single channel memory operation.
  • The Intel® Desktop Board D875PBZ supports 333 MHz PC2700 and 400 MHZ PC3200 DDR memory modules only.
