History

Pete Batard 2faf36ffb4 [core] add FreeNAS support * And reverted grub2 to the one from `b3947fc026` (reverts commit `8b47e95eb5`) since FreeNAS doesn't work with the older one. Sorry "Super Grub2 Disk" and other older GRUB2 based tools, but you'll need to update the Grub version you use if you want to be compatible with Rufus. * Closes #244		2014-12-16 23:28:07 +00:00

readme.txt

This directory contains the Grub 2.0 boot records that are used by Rufus

* boot.img and core.img were compiled from git://git.savannah.gnu.org/grub.git,
  commit 72ec399ad8d6348b6c74ea63d80c79784c8b84ae, on a Debian 7.7.0 x64 system.
  This was done following the guide from:
  http://pete.akeo.ie/2014/05/compiling-and-installing-grub2-for.html.
  Note that exFAT was not included in core.img in order to keep it under 31.5 KB.

* boot.img has been modified to nop the jump @ 0x66 as per grub2's setup.c comments:
  /* If DEST_DRIVE is a hard disk, enable the workaround, which is
     for buggy BIOSes which don't pass boot drive correctly. Instead,
     they pass 0x00 or 0x01 even when booted from 0x80.  */

* Note that, for convenience reasons, the content of boot.img is *not* the one that
  Rufus processes when writing the MBR.
  Instead, the byte array from src/ms-sys/inc/mbr_grub2.h (whose content is identical)
  is what Rufus uses. If you modify these files, be mindful that you may also need
  to update the array in mbr_grub2.h.

* For details, see src/format.c, src/msys/br.c and src/msys/inc/mbr_grub2.h.
