Could you build this?

No Injecting legacy BIOS (CSM) support into UEFI-only firmware requires firmware modification with hardware-specific expertise. Errors can brick machines, so vibe coding is not sufficient.

What it would actually take: This involves extracting and modifying firmware images (UEFI modules, option ROMs, CSM binaries) per vendor and chipset, then testing on many boards with a recovery path. It requires low-level firmware and bootloader expertise, specific hardware for testing, and careful risk management.
