    I downloaded the efi for EMC 2881, flashed it and system was running very slow, so I analyzed and me version was 9.0.5.1367, so I copied that on the bin file but after that system chimes but no display and fans on high speed.

    board number is 820-3737, it is not giving any error while flashing, system just does not boot as intended, you had uploaded bios with clean ME and someone had same issue with it, so I thought you might know what be the cause of it.
