* boot.img and core.img were compiled from
|
2019-07-05 12:31:22 +00:00
|
|
|
https://ftp.gnu.org/gnu/grub/grub-2.04.tar.xz, on a Debian 9.9 x64 system.

This was done following the guide from:

|
* 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.
