From 488242eb941305ef61319b8499d4a1e8ccf218a1 Mon Sep 17 00:00:00 2001
From: Francis Rowe <info@gluglug.org.uk>
Date: Sun, 20 Jul 2014 03:37:00 -0400
Subject: Libreboot release 6 beta 3.

- Fixed typo that existed in 2nd beta where the release date of the
  2nd beta was listed as being in year 2016, when in actual fact it
  was 2014.
- Documentation: added (preliminary) details about (rare) buggy CPU's
  on the ThinkPad T60 that were found to fail (instability, kernel
  panics, etc) without the microcode updates.
- Documentation: added docs/howtos/x60_heatsink.html for showing how
  to change the heatsink on the Thinkpad X60
- Added ROM images for Azerty (French) keyboard layout in GRUB
  (courtesy of Olivier Mondoloni)
- Tidied up some scripts:
  - Re-factored those scripts (made easier to read/maintain):
    build-x60, build-x60t, build-t60, build-macbook21
  - Reduced the number of grub configs to 2 (or 1, for macbook21), the
    build scripts now generate the other configs at build time.
  - Deleted build-x60, build-x60t, build-t60, build-macbook21 and
    replaced with intelligent (generic) buildrom-withgrub script
  - Updated build to use buildrom-withgrub script for building the ROM
    images.
  - coreboot.rom and coreboot_serial.rom renamed to
    coreboot_usqwerty.rom and coreboot_serial_usqwerty.rom
  - coreboot_dvorak and coreboot_serial_dvorak.rom renamed to
    coreboot_usdvorak.rom and coreboot_serial_usdvorak.rom
  - Renamed coreboot*rom to libreboot*rom
  - Made flash, lenovobios_firstflash and lenovobios_secondflash
    scripts fail if the specified file does not exist.
  - Updated all relevant parts of the documentation to reflect the
    above.
- Replaced background.png with background.jpg. added
  gnulove.jpg. (resources/grub/background/)
- Updated buildrom-withgrub to use background.jpg instead of
  background.png
- Updated buildrom-withgrub to use gnulove.jpg aswell
- Updated resources/grub/config/macbook21/grub*cfg to use gnulove.jpg
  background.
- Updated resources/grub/config/{x60,t60,x60t}/grub*cfg to use
  background.jpg background.
- Documentation: updated docs/index.html#grub_custom_keyboard to be
  more generally useful.
- nvramtool:
  - Updated builddeps-coreboot script to build it
  - Updated build script to include it in libreboot_bin
- Documentation: added docs/howtos/x60_security.html (security
  hardening for X60)

 					They will be tested at a later date.
 				</p>
+			<h2><u>*</u> T60 (microcode): some CPU's might not work (can be replaced)</h2>
+				<p>
+					A user with 2 T60's, each with a Core 2 Duo T7200 processor tried libreboot on each machine.
+					One worked, one did not. It should be explained that in addition to the microcode (on the CPU),
+					updates are usually supplied in coreboot (from Intel) which patch the onboard microcode to fix bugs. 
+					Errata's can be found at <a href="http://download.intel.com/design/mobile/SPECUPDT/30922214.pdf">http://download.intel.com/design/mobile/SPECUPDT/30922214.pdf</a>
+					and <a href="http://download.intel.com/design/mobile/SPECUPDT/31407918.pdf">http://download.intel.com/design/mobile/SPECUPDT/31407918.pdf</a>.
+					These microcode updates are not included in libreboot because they are proprietary (blobs). Most CPU's work fine without them: hundreds
+					of Core Duo T2300/T2400/T2500/L2300/L2400/L2500 processors have been tested on the X60, and a few T5600 CPU's have been tested on the T60 (and X60 and all work).
+					In the case of the T7200, it was found that one of the two tested had instability issues (kernel panics) without the updates: work is being done to find out 
+					exactly what version of the microcode that particular CPU had in this case.
+					If you find that your CPU gives you similar issues (after trying libreboot), the current workaround is to simply try another CPU
+					(fortunately, the CPU's in the T60 are installed in a socket so replacing them is easy).
+				</p>
+				<p>
+					There might be a patched kernel that can be used, or a kernel parameter that can be used in GRUB to work around these (rare) buggy CPU's
+					(it is unknown at the moment whether this is possible).
+					The Core 2 Duo T7600 is untested, but will be tested soon (the lead developer of libreboot project has 3 of them to try out). 
+				</p>
+				<p>
+					If reading this for 2nd beta, note that any debugging obtained so far will be included in the 3rd beta.
+				</p>
