5. the Heatspreader onto a COM product The correct installation of the heatspreader onto a COM module is by no means a trivial task and should be done with great care In order to assists its customers in this task MSC has issued a technical document for each of its major product families These documents will ultimately be available on the MSC website but for the time being they can only be obtained by contacting your MSC sales representative FAQ 5 How to reset the BIOS settings to default when the display is not working Blind Occasionally it could happen that a new BIOS setting prevents the display from working for example o The display is changed to TFT and the TFT is not operational o The on board EDID EEPROM is enabled but the contents are not valid In order to get the BIOS back to the default settings and so enable the VGA display the following sequence must be performed o During boot press F2 to get into BIOS setup o Press F9 and then enter to reset to default settings MSC COM boards Frequently Asked Questions PRELIMINARY o Press F10 and then enter to save and exit the BIOS setup o System should then reboot with the default settings 2 6 FAQ 6 How to save and restore the default BIOS settings using uspepc Often it is necessary to have the same BIOS default settings for all the modules used in an end customer system The simplest way to do this is using the DOS utility named UspEpc This utili
6. the default BIOS setup settings for a system which is going to mass production Rather than having the end customer modify the settings himself in the BIOS it is preferable to have the system pre configured with the new default settings The default BIOS settings are stored in the battery backed CMOS RAM In addition with MSC COM products the CMOS settings are also backed up to a small Serial EEPROM on the module The CMOS settings are copied to this back up EEPROM after every successful completion of POST Power On Self Test The following possibilities exist for storing the default setup values for a production series o MSC provides a utility called UspEpc which the customer can use in his production to program the default settings of the system This software is available as a DOS utility alternatively using the Windows or Linux API the customer can write his own application for this This software is available on the MSC Support Website after registration See also FAQ 6 o There is a BIOS editor software which patches the BIOS binary file which is programmed into the COM BIOS flash device Note that not all setup features are stored with this option For example the device boot order is not stored with this option for older modules Please contact your MSC sales representative for more details o The final option is that MSC can produce a custom BIOS for a customer which includes the default parameters preferred This option is not
7. M boards Frequently Asked Questions PRELIMINARY 2 2 1 2 2 FAQ s FAQ 1 Booting headless without display systems Some embedded systems do not include displays or human Interface devices such as mouse and keyboard However when the standard MSC BIOS boots the first time it requires a keyboard to be connected in order to enter the new date and time for the real time clock hence if no display is connected the BIOS will generate a beep error signal and then hang waiting for the appropriate entry to be made from the keyboard In order to get around this problem the following can be done o The default mode of displaying POST errors can be disabled in the BIOS This requires that the BIOS setup be entered and under Boot Options in main menu the entry Post Errors is disabled In order to keep this configuration as the default for production BIOS see details about different possibilities in FAQ 2 o A fast workaround is to connect a keyboard and press F1 this will force the BIOS to continue working and ignore post errors Note this issue can also been seen in following situations o CMOS battery has been removed or is empty o Module is removed and re installed on the baseboard or module is inserted for the first time on a baseboard o There is no CMOS battery backup and power is removed FAQ 2 How to setup new default BIOS settings for production Often it is necessary to change
