well i tried shorting the main bios by connecting pins 5+6 and you can also connect pins 1+7. which is suppose to trick the back up bios into thinking the main bios is not working but no luck.
it seems that the backup bios is not working on both boards, is this even possible? and if so what would of caused this?
from what i gather if you flash the bios in ntfs format flash it will not work, i couldn't find anything to say that it will damage the bios. could it be the tech who flashed it used @bios? and even if he did i should still be able to disable the main bios and make the back up bios take over right?
Im not sure how this dual bios tech works, but I think its possible to corrupt both. Or it just didnt work. So its still the corrupted mainbios thats working, or well not working.
And according to your link (pg 1) it should have been pins 4 und 7. And also its a different mainboard, so even though its the same company they might have changed the layout of the pins.
Can open the link to the datasheet from tgun, its probably to old.
But if you can find out which pins are Data In and Clock for your board...
http://download.gigabyte.eu/FileList/Manual/mb_manual_ga-990fxa-ud3_e.pdf says they use...
wait a sec.... chpt. 2 says you can press END to flash without entering the bios. Did you try that?
anyway, whats the writing on the bios chips? I cant find anything about which chip they use and my kids just woke up.
