Troubleshooting CHAPTER 5 Troubleshooting This chapter provides you a few useful tips to quickly get your ROBO 679 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 ROBO 679 is a full sized SBC and therefore is able to run on any PICMG backplane active or passive ATX power ROBO 679 is designed to support ATX powering Please refer to the following instruction to apply ATX power on your ROBO 679 and backplane Demonstration model Backplane PBP 14P4 ROBO 679 Step1 Remove the jumper on pin3 and pin4 of CN4 ATX P S CONTROL CONNECTOR 4 pin connector see the Figure below CN 4 connector is on the lower left side of the CN 7 ATX POWER CONNECTOR on the backplane 5 1 ROBO 679 User s Manual Troubleshooting Step2 Connect 20 pin power cable of the ATX POWER with the CN7 ATX POWER CONNECTOR 20 pin connector on the backplane The CN7 is located on the upper right side of the backplane with white color Step3 Use a 4pin power cable to connect the CN4 ATX P S CONTROL CONNECTOR 4 pin connector on the backplane ROBO 679 User s Manual 5 2 Troubleshooting Step4 Please find the J5 4 pin header on the center part of ROBO 679 in white color You will also see a mark with J5 at the right top corner of

5. nd mouse A Users may always adopt PS 2 keyboard and mouse over the PS 2 interface through Y cable J18 on ROBO 679 However it is also fine to adopt a standard keyboard over the standard keyboard connector on backplane if provided In this way users need to adopt a 5 pin keyboard connection cable to line up external keyboard interface J22 on ROBO 679 with the 5 pin keyboard connector on backplane Q OK I have finished up hardware installation but got nothing when power on the system Why A There are thousands of different reasons to produce this power on failure 1 Check ROBO 679 jumper JP3 For AT power supply or ATX power supply used for AT system JP3 needs to be at 1 3 and 2 4 Otherwise it needs to be at 3 5 and 4 6 Incorrect power setting will not allow you to power on the system 2 Double check if every connector is attached with the correct cable 3 If you have changed processor with different system clock please move JP2 CM OS clear Jumper to 2 3 power on the system to clear CMOS power off the system move JP2 back to 1 2 and power on again 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 ROBO 679 does not have switch or jumper t
6. o configure CPU core bus ratio This is done through BIOS setting Please check in the Frequency Voltage Control section of Chapter 4 4 11 to adjust this core bus ratio Q I connect two IDE devices over one IDE flat cable but the system either does not start or hangs from time to time Why A Makesure that you have configured the two IDE devices as master and slave respectively ROBO 679 User s Manual 5 5 Troubleshooting Q I am using an ATA 66 hard drive how can know that ATA 66 function is started A You need to use the 80 pin ATA 66 IDE flat cable to have this function ready During POST you can see ATA 66 message while hard drive is being detected 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 168 pin SDRAM keyboard mouse floppy drive IDE hard disk printer VGA connector device power cables ATX accessories or P8 P9 power cable are good examples that deserve attention With no assurance of properly and correctly accommodating these modules and devices it is very possible to encounter system failures that result in malfunction of any device To make sure that you have a successful start with ROBO 679 it is recommended when going with the boot up sequence to hit DEL key and enter the BIOS setup menu to tune up a stable BIOS configuration so that you can
7. oard VGA and Ethernet It is also very common that users would like to disable a certain device port to release IRQ resource A few good examples are disable COM 1 serial port to release IRQ 4 disable COM 2 serial port to release IRQ 3 disable parallel port to release IRQ 7 disable PS 2 mouse to release IRQ 12 we LC A quick review of the basic IRQ mapping is given below for your reference iRO Description It is then very easy to find out which IRQ resource is ready for additional peripherals If IRQ resource is not enough please disable some devices listed above to release more 5 4 OS Diagnostics What will be presented here is a brief guide to properly house in the driver for any Microsoft Windows 95 98 NT device For other operating systems please refer to OS manual guidebook ROBO 679 User s Manual 5 7 Troubleshooting Booting Users may find quite a lot that Windows 95 98 hangs in loading sequence Windows logo stays with no progress or simply no display is given Please restart your system and hit F5 when loading the Windows system and enter Safe mode Users will always be allowed to enter Safe mode with success to remove devices that are not properly running or installed Please proceed to do so and restart your Windows Removed devices will be automatically detected again and drivers will be loaded in if drivers have been copied in the system database or you will be asked to provi
