[Bug 883017] Re: memtest86+ fails on efi systems

[Bernard Burette]

Hi,

I have built a version of memtest86+ that looks like a bzImage not a
zImage and can be loaded and run from EFI-GRUB, I would be pleased to
release this code, but I don't know where nor how to do it. I'm I at the
right place ?

Regards,

Title:
  memtest86+ fails on efi systems

Status in “memtest86+” package in Ubuntu:
  Triaged

Bug description:
  memtest86+ fails to load on an amd64 in EFI-mode system using grub-
  efi, I do not know if the error also occurs when using grub-pc on
  amd64.

  Memtest86+ entries are included in the GRUB boot menu. Booting these options results in an error however:
  'error: unknown command 'linux16'.'

  Changing linux16 to linux results in another error:
  'error: zImage doesn't support 32-bit boot.'
  (bug #424506)

  It seems grub-efi (or maybe actually grub on
  amd64(http://www.gnu.org/software/grub/manual/grub.html#linux16) does
  not support linux16.

  I have not found a solution. If there is no solution yet, I would
  suggest not adding the Memtest86+ boot options on amd64 systems (I
  believe efi&64 bit support is planned for memtest86+ version 5)
