GRUB2
There is a mistake about the platform target: GRUB_PLATFORM="efi-32" (cf. GRUB2) -- Feng (talk) 11:02, 10 October 2016 (UTC)


 * What is the mistake, exactly? --Maffblaster (talk) 01:36, 3 February 2017 (UTC)


 * I see the mistake for 32-bit OSes. I'll have to create a transclustion for the x86 Handbook. Thanks for the heads up! --Maffblaster (talk) 01:53, 3 February 2017 (UTC)


 * Issue is now resolved. x86 CPUs (when attempting to use UEFI) will now use,  , and hopefully output the  file. Please reopen if I made any errors there. --Maffblaster (talk) 17:56, 28 March 2017 (UTC)

Efibootmgr
UEFI images are defined for several architectures or "machines types". The EFI stub kernel is a UEFI image and is named bootIA32.efi because the machine type for the x86 architecture seems to be "IA32" in the UEFI specification.

 * Hi, yes, this does seem to be true for EFI stub kernels. I have updated the article to properly reflect the official name for both the amd64 and x86 handbooks. Thanks for your help in pointing out this error. Kind regards, --Maffblaster (talk) 17:56, 28 March 2017 (UTC)

UEFI on X86
UEFI is not dependent on the Arch bitness. It is determined by the firmware's bit which is usually 64-bit.

I have only heard of Intel Macs which are UEFI-32.

People install X86 arch on 64-bit capable machines and UEFI and will be confused by the settings from the above discussions.

If you want to use the efi-32 targets, this needs to be clarified. --Grknight (talk) 18:04, 28 March 2017 (UTC)


 * I think, because of our chat on IRC the other day and what you said here, I understand more clearly now. I'll switch things back to the way they were before and simply make a note about 32-bit EFI not really being a thing. With that being said, you mentioned older Macs supporting it and I found this StackOverflow thread mentioning a tablet with a Intel Atom Z3740D CPU that had seems to have 32-bit EFI. Thank for the help with the Handbook! --Maffblaster (talk) 17:45, 21 April 2017 (UTC)


 * Excuse me Grknight, I do not understand your affirmation: "People install x86 arch on 64-bit capables machines and UEFI [...]"! How can we  install  an architecture? --Feng (talk) 06:10, 22 April 2017 (UTC)
