This directory contains the Grub 2.0 boot records that are used by Rufus
|
|
|
|
* boot.img and core.img were compiled from
|
|
http://ftp.gnu.org/gnu/grub/grub-2.02.tar.xz, on a Debian stretch x64 system.
|
|
This was done following the guide from:
|
|
http://pete.akeo.ie/2014/05/compiling-and-installing-grub2-for.html.
|
|
--enable-boot-time was also added during ./configure for Manjaro Linux compatibility.
|
|
|
|
* 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. |
