" rel="nofollow - I have a strange problem with my EP2C602 motherboard. I am using the 1.89 BIOS. My problem is that I cannot get any device attached to the two on board SATA III ports to appear as a bootable UEFI device. I am using a SATA III Samsung SSD and I am not yet using NVMe (I was waiting to buy one after I get this all sorted out). The drive will appear as legacy but not UEFI. Unfortunately I must be able to boot the OS as UEFI. Oddly my USB installers will appears as UEFI bootable. Any thoughts or suggestions? Motherboard: ASRock Rack EP2C602 Processors: 2 x E5-2680 v2 Memory: 64gb Samsung DDR3R ECC GPU: EVGA 980 Classified |

" rel="nofollow - I decided to roll back to v1.80 BIOS. Since the 1.89 is not official, I wanted to reduce variables. I am now on the most recent officially released and supported BIOS build. That did not change or alleviate my issue. I tested my drives to make sure it wasn?™t on my end. I removed the bootable OS drive from a different machine with a Gigabyte motherboard and placed it in this computer. I also took the drive from this computer and put it in the Gigabyte machine. The main drive from the EP2C602 shows as UEFI on the other computer but the drive from the Gigabyte does not show as UEFI on the EP2C602. The problem clearly is that this board is not scanning or recognizing UEFI boot ability for these SATA ports. It works on USB drives. |

| " rel="nofollow - I cannot access bcfg. Here is another post about the issue - http://forum.asrock.com/forum_posts.asp?TID=3211. I tested both 1.80 and 1.89 BIOS. I can't manually edit bcfg and also the BIOS doesn't see my SSD as a UEFI bootable drive (as noted above). However, I can manually launch my OS bootloader without issue from within the shell (fs1:\EFI\BOOT\BOOTX64.EFI). So weird. |
