Live CD: memtest is missing in UEFI mode #26815

Open bjornfor opened 7 years ago

bjornfor commented 7 years ago

Issue description

The NixOS live CDs / default installer media contains a memtest86+ entry when booting in BIOS mode. But it's missing when booting in UEFI mode.

Can we add memtest to the UEFI mode?

Steps to reproduce

  1. Download NixOS 17.03 iso from https://nixos.org/
  2. Boot in BIOS mode, see the memtest86+ entry
  3. Boot in UEFI mode, memtest86+ entry missing

memtest86+ is not compatible with UEFI mode, I suppose. The proprietary memtest86 does, but is marked as broken at the moment.

Ok, closing then.

Re-opening since memtest86+ is compatible with UEFI now (from https://memtest.org/):

Memtest86+ can be loaded and run either directly by a PC BIOS (legacy or UEFI) or via an intermediate bootloader that supports the Linux 16-bit, 32-bit, 64-bit, or EFI handover boot protocol.

I noticed that neither Fedora nor Ubuntu have memtest entries in their live images, and that https://www.memtest.org/ releases ISO files, which I can drop into my USB drive with Ventoy.

I'm no longer so sure we should add it.
