This honestly makes some sense though. Legacy bios is virtually dead on all modern systems. CSM still exists on some stuff but it’s fading out. The A20 gate no longer exists, the PC industry is moving on. DOS on real hardware at this point is just going to get progressively more and more rare as the hardware further diverges from the IBM PC heritage it’s clung to. Real mode is the next thing on the chopping block and that will completely kill the legacy bios and DOS outside of VMs.
