I'm not aware of DRM BIOSes which stop you running non-approved OSes; however
if you do so, then you won't be able to run DRM-aware applications, because
the chain of assurance from hardware (TPM) to BIOS to OS to Application is
broken (and that's what DRM-aware applications look for before they'll let
you play with copyright materials).
As far as I'm aware, all current DRM / TCPA / TCG implementations allow you to
boot whatever you like, but if it's not a certified OS then DRM applications
simply won't play ball.
Obviously if you start LinuxBIOS instead of the motherboard vendor-supplied
BIOS, you simply ignore the existence of the TPM chip/s.
