What I'm worred about is SMI traps implemented in the SBIOS for AHCI
workarounds that may be disabled when in IDE mode.
For Nvidia devices those would only be present if there were problems
with the AHCI hardware right, which would mean you could simply tell us
what workarounds to implement.

Prior to force-enabling ahci there is one device that sees the 2 sata
