|Question #325:||How can I reset the BIOS settings to factory defaults?|
|Answer:||There is a special menu entry in the BIOS setup screen, which will reset all BIOS settings to their factory defaults.
If entering the BIOS setup screen is not possible, the recommended way is to switch off the CMOS backup power (either by removing the CMOS battery completely from its holder or by using the corresponding DIP switch as described in the product "User Manual"). That way, the BIOS settings are gone and the default ones are loaded at next system boot. After the system has booted successfully, don't forget to connect/switch on the CMOS backup power again.
|Question #247:||My MPL SBC does not [boot|start] up. What can I do?|
|Answer:|| First of all, what precisely is meant by "does not [boot|start] up"?
Is the system not powering up at all or is there some reaction / output from the BIOS/bootloader, but no operating system is loaded or started?
If it is the former, please do the following:
Please note that the above is just a rough list of things to check and try. Please use the corresponding manual for detailed information and precise instructions for a particular MPL product.
|Question #228:||I observe power-up problems or sudden, unmotivated resets of the MPL SBC during normal operation. It seems to get worse if an additional add-on card is installed and/or the CPU and/or GPU load is increased.|
|Answer:||Sounds like the external power supply is unable to sustain the highly dynamic power requirements of most modern CPUs.
|Question #248:||The RESET LED is blinking. What's wrong?|
|Answer:||This means that the internal power supply of the SBC has detected an overload or even short-circuit condition on one of its power rails.
Please follow the steps below:
|Question #351:||Since I updated to Linux Kernel 2.6.30 or higher, all I2C peripherals (like temperature sensors or EEPROM) are not working any longer. With an older kernel, everything is working fine.|
|Answer:||Is there a message similar to:
If yes, please add "acpi_enforce_resources=lax" to the kernel command line.
