The standard Asus BIOS for this motherboard doesn't support booting a Samsung XP941 NVMe SSD (MZHPU512HCGL-00000). Using the MMTool Aptio a bootable BIOS was generated by using the Samsung_M2_DXE from a Asrock BIOS. This steps are only appropriate for motherboards with AMI BIOS. At the time of writing the UBU (UEFI BIOS Updater) v1810 supports Aptio 4 BIOS - newer X99 chipset boards are not supported by this version. This documentation is the minimum I had to do to get the BIOS booting. I also opened a support ticket with ASUS but that has proven to be fruitless.
Add the SAMSUNG_M2_DXE file to the Asus motherboard fileĭownload the UBU rar from and put the files into a directory.Extract the SAMSUNG_M2_DXE file from a BIOS.This should serve as a good advertisement for the BIOS support in Asrock motherboards.
