I do not know who elected to move this topic, appropriately originated on the Chat Subgroup, here, and I am presuming it is accidental.
That being said, this topic is now locked. We absolutely know that BIOS/UEFI is not accessible using NVDA, JAWS, Narrator, or any of the other now out-of-support Windows platform screen readers. It's not going to become so using any of those screen readers, because it can't, since UEFI/BIOS access must occur before Windows is running, and Windows must be running before the screen readers listed can run.

[Regarding the Supreme Court refusing to hear the case brought by Texas to overturn the votes certified by 4 states:] Pleased with the SCOTUS ruling, but also immediately slightly terrified of where this crazy train goes next. We should know by now there’s a bottomless supply of crazy.
