Some x86 systems might be capable of running a 64-bit Linux kernel but only use a 32-bit EFI (e.g. Intel Bay Trail systems). It's useful for grub-install to be able to recognise such systems, to set the default x86 platform correctly. To allow grub-install to know the size of the firmware rather than just the size of the kernel, there is now an extra EFI sysfs file to describe the underlying firmware. Read that if possible, otherwise fall back to the kernel type as before. Signed-off-by: Steve McIntyre <steve@einval.com>
This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. Please look at the GRUB Wiki <http://grub.enbug.org> for testing procedures. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
