I have two of d510mo boards. One with bios version 0148 and newer with bios version 0516.
With second I have booting problem when I use a USB device for my car, Joycon
Booting stacks with postcode 5A and do nothing until remove USB device. I have disabled USB Legacy from bios and all other options with usb.
The other board with version 0148 has no booting problem with this device! I have disabled USB Legacy and works perfectly!!
I also have a problem with the sound card. When PC starts, a instantaneous annoying big noise sounds!! But with 0148 version just a normal beep sounds. I tried to downgrade bios, but the only version that it accepts is 0516. Is there any solution?
