Not really, BIOS is old and it doesn't know anything about OPAL drives. I don't know about UEFI machines but I suspect not many know about SEDs/OPAL either. By BIOS, I meant UEFI, sorry about that. My UEFI is from 2013 (Dell Latitude) and it knows enough about SEDs. I use SSDs and I use Hardware Based Encryption with it (Samsung 850 Evo).
On the other hand, you don't know what kind of treatment the BIOS would do to the password before sending it to the SED, one bios could send it plaintext, others could send key scancodes, you don't want to get anywhere near that kind of nonsense. This would mean that you might not be able to unlock the disk if you move it to another machine. That is something I have never paid any attention to. But I can set a password through the linux's hdparm utility, and then you can unlock it from the the BIOS and vice-versa. So, I think that makes it standard enough, but not sure.
