Hi, I bought a Terramaster F2-221 only to find that the BIOS is set by default to boot from the two hard drives and I need to boot from USB where I installed OpenMediaVault, however the option to change the boot order in the BIOS has been disabled and grayed out by Terramaster. I have found in other forums that you should change CSM settings and set to UEFI mode however I can only boot in legacy mode. I find it strange that Terramaster would do this to the BIOS in order to cripple it from using it with other OSes. Can someone help? By the way the BIOS is American Megatrends version 2.18.1263
