tianocore VS edk2

> someone would have to pay a team of engineers to rewrite everything

A partial effort has already been made a while back: https://github.com/tianocore/edk2-staging/tree/edkii-rust

However, this uses uefi-rs, which is incompatible with TianoCore's BSD+Patent licensing, and therefore cannot be used as reference material, as the wiki page states: https://github.com/tianocore/tianocore.github.io/wiki/Tasks-...

More recent efforts have also been mentioned in the mailing list: https://edk2.groups.io/g/devel/search?p=recentpostdate%2Fsti...

Who and what? https://github.com/tianocore/tianocore.github.io/wiki/UEFI-EDKII-Learning-Dev ton more resources: https://github.com/tianocore/tianocore.github.io/wiki/Additional-Projects

Intel has opensource training on EFI/UEFI and the whole boot process. https://github.com/tianocore/tianocore.github.io/wiki/Traini...

I think you should try install edk2 UDK2017 with this link. I installed a while back and it worked.

By compiling OvmfPkg of TianoCore's EDK II.

This involves recompiling OVMF with Secureboot and TPM capability and compiling swtpm and libtpms for emulating a TPM2, so quite some work to get it up and working. All of this assumes you are using the root user. The steps for compiling are roughly this guide: https://github.com/tianocore/tianocore.github.io/wiki/Common-instructions

For the modern server/desktop and even laptop, that's also no bad thing. It is somewhat ridiculous that UEFI bioses, internally, still boot in 16-bit real mode and have to do all the steps your bios bootloader used to do to set up a 64-bit environment ready to go: https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a...

Why not just start the CPU in "long mode", which is what everyone is using it for, in the first place?

These newer ARM processors support 32-bit code at EL0 only (userspace). That seems like a reasonable approach for x86 as well and the freebsd announcement has this to say:

> There is currently no plan to remove support for 32-bit binaries on 64-bit kernels.

So for the moment, you can run 32-bit applications just fine.

Download this UEFI shell and place it in the BOOT subfolder

They could have at least informed TianoCore. the affected code in edk2 hasn't been modified in 2 years.... https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Library/BaseBmpSupportLib/BmpSupportLib.c

I have half fixed it.. Using this solution: https://github.com/tianocore/edk2/discussions/4662

You need only EDK2 and some lööps.

What is the difference between this and https://github.com/tianocore/edk2

From there you'll need to get an EFI Shell. There may be one built into your system, but you can also get one here from Tianocore (aka, the people mostly making UEFI). Neither this EFI Shell nor Keytool.efi (the thing you need to load the keys) are signed of course, so you will need to turn off SecureBoot to continue. From there just run Keytool with your new keys, turn back on SecureBoot, and move on with your life.

I had the same issue. What fixed it for me was compiling my own OVMF.fd file from here and using that to boot. The version of OVMF that shipped with fedora was broken for me for some reason.
