How do I stop the R210 bios issuing an ATA SECURITY FREEZE command?

It looks like the Poweredge R210 BIOS (but NOT the R210a BIOS) issues an
ATA SECURITY FREEZE command to all attached SATA drives on power-up. 
This stops any ATA security commands being issued to the drive under
Linux (e.g. SECURITY ERASE UNIT etc.).

How do I stop it doing this?  I don't think I can see any options for it
in the R210 BIOS UI (v1.8.2).

Is there a non-UI-visible setting I can change to disable this "feature"
(i.e. by setting a "CMOS token")?
