This BIOS dump came from a Samsung Galaxy Pro NP950XDB-KC3US that will NOT POST. It powers on, has keyboard backlight, fan spin, and a flashing blue LED near the USB-C port.
I don't know if anyone here can clean this BIOS dump for me. I have purchased an identical used motherboard, which will arrive next week. I should be able to get a good BIOS dump from that working board.

I doubt this will help, but I have uploaded a BIOS dump from a Galaxy Book Pro that does NOT POST. I hope I can get it cleaned one day, but I need to find a dump of a working BIOS for this model. The Venus-15 BIOS dumps may work. I will try them.
