|
* core.img was compiled from grub 2.00-22 using the tarballs found at
|
|
|
|
|
https://launchpad.net/ubuntu/+source/grub2/2.00-22.
|
|
|
|
|
The use of the 2.00-22 source is done for compatibility reasons.
|
|
|
|
|
|
|
|
|
|
* This was done on a Debian 7.7.0 x64 system using gcc-multilib 4.7.2, 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.
|
|
