I only have one thought on the matter:

What RAM are you using?

Based on your description I get the feeling it may not be properly supported by the board and could be what keeps flagging Boot Failure Guard. If the RAM is higher than default DDR3 voltage, 1.65v vs 1.5v or 1.3v (low votlage) it could be triggering BFG. If you have not already I would try some standard DDR3 1333 or 1600 in there and see if it still causes the error. Even if the voltage is 1.3v or 1.5v the module might not be fully supported.

Just my 2c on the issue, please feel free to ignore if you have already tried multiple RAM brands and models.


Kingston KVR16LS11/4 as recommended http://www.asrock.com/mb/Intel/Q1900TM-ITX/?cat=Memory but only one slot - so it is single channel 4GB.

But dunno is it worth of hassle, I should stick with Gigabyte, the only manufacturer which never, ever disapointed me.

Now I found what causes few wierd errors...

Battery (CMOS) died and every hardware setup causes loading default, because I pull out adapter jack every time when do some hardware job. I do it on every pc weather or not is switched off  as precaution.

But why almost new CMOS battery died?
Following factory recommandations "The DC-In jack is compatible with the 19V power adapter", I connected power supply and motherboard step-down DC to DC converters (which are poor designed) dissipated huge amount of heat to destroy near placed CMOS battery in short time. That is both buck converters design and MB design layout failure. Pitty, because AsRock makes very good MBs, and the company is very inventive.

I solve it by, ofcourse, replacing battery and new AC adapter of 12V output!!!! This is what NOT should be done, because common buck converters can't handle same input-output voltage. That achieved veeerrrryyyy low dissipated heat, and 12V trail is now at about 9V, but while is not needed for attached SSD, or any other job, it is boilerplate solution.

STILL we have an issue with Grub erasal which is not tolerable :(
