Arch Linux

Description:

Some machines like the "ASUS T100" and some MACs are UEFI class 3 systems that only like to boot from a bootia32.efi loader even though their architecture is x86_64.

By applying the changes below to the grub PKGBUILD will make archlinux more compatible out of the box for these machines.

These changes were found inside the PKGBUILD of ``grub-git`` package from AUR, I believe these changes should be considered in the core grub PKGBUILD.

edit ``PKGBUILD`` add the following to the top
::

## "1" to enable IA32-EFI build in Arch x86_64, "0" to disable
_GRUB_IA32_EFI_ARCH_X64="1"

edit ``PKGBUILD`` at the bottom of ``build()`` function add
::

if [[ "${CARCH}" == "x86_64" ]] && [[ "${_GRUB_IA32_EFI_ARCH_X64}" == "1" ]]; then
msg "Build grub i386 efi stuff"
_EFI_ARCH="i386" _build_grub-efi
echo
fi

edit ``PKGBUILD`` at the bottom of ``package()`` function add
::

if [[ "${CARCH}" == "x86_64" ]] && [[ "${_GRUB_IA32_EFI_ARCH_X64}" == "1" ]]; then
msg "Package grub i386 efi stuff"
_EFI_ARCH="i386" _package_grub-efi
echo
fi
