AMI BIOS boot options?
What are these boot options in (ReadyNAS RN312) AMI BIOS? Default boot option 1: SMI USB DISK 1100 Default boot option 2: UEFI: SMI USB DISK 1100 Are they both pointing to the same target? ...

Sorry, don't know what else can be done. mine is 628X, and don't think that will be reason.
tbh, I don't think I follow what you did.

I solved it!
I blame TinyCore for this.*
Today I tested to boot up OpenMediaVault (with same USB stick as for TinyCore) and it presented itself with both legacy and UEFI. I tested both and RN312 could boot from both OMV's legacy and UEFI and the setting stuck in BIOS! Now the machine boots up from the OMV external USB every time.
OMV boot could be place in position/slot number 3 and having internal flash in 1 and 2 disabled. Or setting OMV in position 1. So the external boot priority position could be elevated/moved, the critical thing was that internal flash was not enabled with higher priority than the external boot.
No other setting needed to be changed in BIOS.
This also explains why most users don't report any problems booting from external USB. They where lucky with a boot device that was fully compatible ReadyNAS OS's BIOS.
* Note: TinyCore only had legacy boot.
