Or you could do what I did after fighting with an msi board for several years a decade back, feed it to the trash can and replace it with an ARK shoebox w/intel atom D-525-MW motherboad that was just enough power to get the job done, and Just Worked for a decade. But just in the last 90 days has been replaced with a stack of Dell 7010's with i5 cpu's, off lease stuff for $150/copy. Much faster stuff, and makes 4 of the 6 running in my farm identical. Simplifies things quite a bit. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
