Star Labs’ take on the matter.

Furthermore, if one is sensitive regarding their cybersecurity, then one is likely to adhere to the zero trust security model and thus choose to simply not trust; which would include the closed source BIOS. coreboot, on the other hand, at least allows one to audit it themselves. As Linus Torvalds has been approached for implementing backdoors, it should surprise nobody that (some) of the vendors we buy our devices from have been as well and thus our BIOSes might not have been as safe as one would like to believe. Qubes OS, the most secure OS on desktop, shares the view that coreboot is preferred over closed source BIOSes due to reasons related to trust.

There can be. There are certainly Bios’ that don’t give options that motherboards are perfectly capable of changing. I had an old Phenom II that I managed to patch NVME support into the bios so I could boot off of a PCIe Riser.

Granted, I was patching UEFI stuff and none of it was open source – but the idea is the same. Open source bios in theory, could unlock features.

@FQQD @p_q if you want that hardware to support something the manufacturer will not support, open source bios can be useful.
