I just bought a PowerEdge T30,and add a M2 SSD (SAMSUNG 960 EVO).

The BIOS Version from the factory is 1.0.0.When I Update the BIOS from 1.0.0 to 1.0.2,Everything is ok.

When I Update the BIOS from 1.0.2 to 1.0.3 ,Sytem can not reboot.

I Found there is no M2 Slot Displayed in the BIOS,and no M2 SSD Displayed also.

When I Update the BIOS from 1.0.2 to 1.0.5 ,the problem remains unsolved.

Dell 's Support Page says: The BIOS 1.0.3 Fixes:Address a problem where SETUP MENU appears non exist M.2 device.

Why did I have the opposite problem when I upgraded the system BIOS？
