Fedora considers deprecating legacy BIOS

• BootDuet

  1 29 10.0 Assembly

  Boot sector program for booting Intel's EDK Developer's UEFI Emulation (DUET) from hard disk with LBA.

UEFI emulation is a thing.

For people with legacy-only firmware systems, you too can run UEFI on lazy cloud providers and legacy hardware. I do this on my 14 year old dell laptop just so that all my x86_64 systems have the same boot efistub linux kernel images. All you need is to use one of the EDK DUET bootloader builds such as BootDuet¹, or for an easier user experience CloverBootloader². Only complaint is secureboot emulation can be a pain. But I imagine with Windows 11 around the corner requiring TPMs, emulators with this feature will probably get more popular.

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• swtpm

  14 526 7.7 C

  Libtpms-based TPM emulator with socket, character device, and Linux CUSE interface.

Seems there are two such projects for that:

  EFI FileSystem drivers

EFI doesn't actually mandate FAT for the system partition. The system partition can be any filesystem that the firmware supports.

Of course, pretty much all EFI implementations only support FAT, so it's a bit of a moot point; the only one I'm aware of that supports anything else is the one on Intel Macs, which also understands HFS+.

You can find a huge selection of EFI filesystem drivers at https://efi.akeo.ie/ but they're derived from GRUB and hence GPL, so don't expect the likes of American Megatrends to be bundling these any time soon.

• libvirt

  12 - -

Perhaps this is a good time to ask: I'd like to use UEFI for my qemu+libvirt virtual machines, but I need snapshot support. Since QEMU doesn't support pflash internal snapshots <https://gitlab.com/libvirt/libvirt/-/commit/9e2465834f4bff40...> and libvirt can't revert or delete external snapshots <https://bugzilla.redhat.com/show_bug.cgi?id=1519002>, I don't see a way to achieve this. The issue was discussed on virt-tools in 2017 <https://listman.redhat.com/archives/virt-tools-list/2017-Sep...> and the situation appears to be unchanged. Do others have a workable solution?
