Troubleshooting Chapter 5 Troubleshooting This chapter provides you a few useful tips to quickly get your 96M4011o running with no failure. As basic hardware installation has been addressed in Chapter 3, this chapter will basically focus on system integration issues, in terms of backplane setup, BIOS setting, and OS diagnostics. 5.1 Backplane Setup Backplane 96M4011o is a full-sized SBC, and therefore is only able to run on PICMG PCI/ISA Backplane.
Troubleshooting Step2: Connect 20-pin power cable of the ATX POWER with ATX POWER CONNECTOR (20-pin) on the backplane. Step3: Use a 4-pin power cable to connect the ATX P/S CONTROL CONNECTOR (4-pin) connector on the backplane. Step4: Please find the J29 4-pin ATX Power Control Connector on the right part of 96M4011o in white color. You will also see a mark with “J29” on the lower side of J29 header. Connect the 4-pin ATX power control cable with this J29 header.
Troubleshooting Step5: Please adjust the AT/ATX jumper on JP3 to short 3-5,4-6 pins, then it can support ATX power scheme. Step6: Connect TOGGLE SWITCH with J32 connector on 96M4011o. Step7: The figure below is the TOGGLE SWITCH, which is used to switch the ATX Power on/off for SBC. Usually the TOGGLE SWITCH is located on the chassis front panel. Pressing the switch button once will turn power on, and press again to turn it off.
Troubleshooting Q: How can I build up an AT system using ATX power supply A: Do not forget to move JP3 of 96M4011o back to 1-3 short and 2-4 short (support AT function). If the ATX power supply has a switch, such as ORION-300ATX, do not remove the jumper of backplane connector in step 1, and use the power supply switch as the system power on switch. In all cases, users may apply a 2-pin AT (on/off) switch over pin-3 and pin-4 of the backplane connector in step 1.
Troubleshooting Q: I power on the system, but the CPU speed is not correct. Why? A: This applies to Engineering Sample processor ONLY. If you have ever loaded the BIOS optimal default, thank you for doing so. However, this will force the BIOS to pick up the default CPU core/bus ratio as well. It needs to be emphasized again that 96M4011o does not have switch or jumper to configure CPU core/bus ratio. This is done through BIOS automatically.
Troubleshooting 5.3 BIOS Setting It is assumed that users have correctly adopted modules and connected all the device cables required before turning on AT power. CPU, CPU fan, CPU fan power cable, 184-pin DDR SDRAM, keyboard, mouse, floppy drive, IDE hard disk, printer, VGA connector, device power cables, ATX accessories or 12V 4-pin power cable are good examples that deserve attention.
Troubleshooting disable PS/2 mouse to release IRQ #12, …, etc. A quick review of the basic IRQ mapping is given below for your reference.
Troubleshooting For Windows-NT 4.0 users, it is always not recommended to change your hardware configuration after your first installation. However, if such a change is needed, please note that sometimes Windows-NT 4.0 will stop loading and prompt you with a whole page of error messages. Please note that reinstallation of this NT hard disk is inevitable. You have to backup your data stored in this hard disk because it is almost impossible to switch back this system unless booting up with another hard disk.
Troubleshooting Windows-NT 4.0 users. 1. Please install your network adapter manually in Control Panel -> Network -> Adapter. Drivers are required at this stage. 2. Proceed “Binding” after you load in the driver. 3. Change to Protocol label and load in the protocols that you are interested (generally, TCP/IP). Configuring IP, gateway and DNS is required for TCP/IP protocol. 4. Proceed again “Binding” after you complete the protocol loading. 5. Restart your system. 6.
