Dell Security Manager requires password

[russfink]

More a question than an issue. I configured an Opal drive w/sedutil-cli and installed it in the secondary internal drive bay. When I boot the system, the Dell system asks for the password - not the PBA. I can press enter three times, it complains, then proceeds to show me the PBA. I suspect the power-on sequence is activating the Opal drive, which is returning a code to the BIOS that "I am locked," and the BIOS "helpfully" intervenes and asks for the password. I don't want it to do that, I want all passwords to go through my PBA image.

My question is, how can I stop the Dell BIOS from asking for the password, and instead let the PBA handle it? Is it a case of setting the SID and Admin passwords to something different, or is there some flag I can set with sedutil-cli to disable that behavior of the Opal drive, maybe some setting in Samsung Magician, or something else? I'm using a Samsung SSD 980 drive.

My bad - the shadow MBR was not enabled; therefore, the BIOS decided that intervention was necessary and supplied its own password collector. Pretty helpful to know, in case anyone else runs into this.
