Amd radeon vii cards do not have uefi support

In what appears to be a massive AMD quality control bug, people who purchased the AMD Radeon VII graphics have reported that their cards do not have UEFI support, so when installing them on their machines the motherboard activates the CSM ( Compatibility Support Module ), a component of the UEFI firmware that is required to start the system when non-UEFI-compatible hardware exists.

The TechPowerUp website has wanted to confirm the claims and using a hex editor with a Radeon VII card and what they have found has been surprising.

AMD Radeon VII cards completely lack UEFI support, even missing the graphics output protocol (GOP) driver that allows basic actions to be performed with the card before system startup.

Without UEFI support for graphics cards, Windows 10 cannot ensure secure boot, therefore, since secure boot is a requirement for hardware to carry the Windows 10 Compatibility Certification logo, right now AMD cannot. Say these cards are compatible with Windows 10, at least not until there's an update.

ASRock is the first AMD partner to release a BIOS update to correct the bug. And while this update was designed for Radeon VII Phantom cards, it works on any Radeon VII card, so flashing it on ASRock card or any other AMD Radeon VII card won't cause any problems.

Checking the ASRock update file you can see that it already has support for UEFI, including the GOP micro-controller. All AMD Radeon VII cards on the market are likely to lack UEFI support, however it didn't take long for all AMD partners' BIOS to update.
