excuse me.

I was previously an ethos user, and I just want to switch to smos.
I already paid deposit fee.
why the media that I give smos is always not readable in the bios? so i can not boot to smos.

I've tried to use flash, ssd & hdd the results are also the same, when I fill the smos is always not readable by bios.

I've tried using various software, such as: hddraw copy, etcher, rufus. but the result remains the same as above.

what's the solution?

hardware specifications:
motherboard asus b250 mining expert
vga 12pcs x rx 580
ram 8 giga.
psu 2 x corsair ax1200i
procie intel g4400

after and before thank you very much.
