Libreboot release 6 beta 4.r20140729
- Documentation: improved (more explanations, background info) in docs/howtos/x60_security.html (courtesy of Denis Carikli) - MacBook2,1 tested (confirmed) - macbook21: Added script 'macbook21_firstflash' for flashing libreboot while Apple EFI firmware is running. - Documentation: macbook21: added software-based flashing instructions for flashing libreboot while Apple EFI firmware is running. - Reduced size of libreboot_src.tar.gz: - Removed .git and .gitignore from grub directory (libreboot_src); not needed. Removing them reduces the size of the archive (by a lot). GRUB development should be upstream. - Removed .git and .gitignore from bucts directory (libreboot_src); not needed. Removing them reduces the size of the archive. bucts development should be upstream. - Removed .svn from flashrom directory (libreboot_src); not needed. Removing it reduces the size of the archive. flashrom development should be upstream. - Added ROM's with Qwerty (Italian) layout in GRUB (libreboot*itqwerty.rom) - Added resources/utilities/i945gpu/intel-regs.py for debugging issues related to LCD panel compatibility on X60 Tablet and T60.
