Common Problems and Solutions The following table lists some of the common problems you may encounter while using your cpu- Module, and suggests possible solutions. If you are having problems with your cpuModule, please review this table before contacting technical support. Problem Cause Solution cpuModule "will not boot" no power or wrong polarity check for correct power on PC/104 bus connectors does not recognize Setup changes will not boot from particular drive or device Atmel Flash shows disk space available, but it cannot be written will not boot from DiskOn- Chip® incorrect Setup (video disabled, etc.) defective or mis-connected device on bus cable connected backwards SSD installed backwards jumper JP5 installed device not bootable device not formatted power not connected to boot drive part smaller than 1.44MB was formatted as 1.44MB; it will show space available even when full DiskOnChip® is not the only hard drive in system using wrong DiskOnChip® device (not 32 pin) Boot device not set to Hard disk install jumper JP5;reboot and press {Del} key to run Setup check for misaligned bus connectors; remove other cards from stack verify all cables are connected correctly check for an SSD memory installed in socket backwards turn off power, remove JP5, reboot use sys command on drive or re-format the device using the /s switch format drive using /s switch connect power cable to floppy or hard drive ignore "disk space remaining" messages from DOS REMEMBER! A bootable disk contains 3 hidden files plus format info, totalling about 150kB disable other hard drive(s) in system change to correct (32 pin) DiskOnChip® run Setup and set boot device to Hard Drive 106
erratic operation excessive bus loading reduce number of PC/104 modules in stack; remove termination components from bus signals; remove any power supply bus terminations power supply noise power supply limiting temperature too high examine power supply output with oscilloscope; glitches below 4.75Vdc will trigger a reset; add bypass caps examine power supply output with oscilloscope; check for voltage drop below 4.75V when hard drive or floppy drive starts; add bypass caps add fan, processor heatsink, or other cooling device(s) See 686GX233 Thermal Management. memory address conflict check for two hardware devices (e.g. Ethernet, SSD, Arcnet, PCMCIA) trying to use the same memory address check for two software devices (e.g. EMM386, PCMCIA drivers, etc.) trying to use the same memory addresses check for hardware and software devices trying to use the same memory address check for an address range shadowed (see Advanced Setup screen) while in use by another hardware or software device I/O address conflict check for another module trying to use I/O addresses reserved for the cpuModule between 010h and 01Fh keyboard does not work Windows 3.1x installation program hangs keyboard interface damaged by misconnection wrong keyboard type smartdrive enabled check for two modules (e.g. dataModules, PCMCIA cards, Ethernet) trying to use the same I/O addresses check if keyboard LEDs light verify keyboard is an 'AT' type or switch to 'AT' mode remove smartdrive command from config.sys, reboot, run install program floppy drive light always on cable misconnected check for floppy drive cable connected backwards 107
