<p>
<b><i>"Release"</i></b> means that a new coreboot git revision with substantially different code has been adapted for libreboot.
</p>
<p>
<b><i>"Revision"</i></b> means a modification to an existing release, where the result is insubstantially different from what preceded it.
</p>
<p>
The 1st, 2nd, 3rd and 4th releases were really just older revisions of the 5th release.
For historical reasons (and to avoid confusion), these are still called 'releases' instead of correcting the mistake.

<p>
Reasons are given in the documentation. If you have one of these machines,
then you can look at the documentation for how to remedy the situation (hardware modifications).
</p>
<p>
T60 15.1" QXGA (2048x1536) with Intel GPU currently does not show GRUB visually (the serial output works), although everything after GRUB is working.
A proposed (untested) workaround for GRUB is to lower the screen resolution for that machine (only in GRUB), or try to fix it (the current theory is that not enough memory is
allocated for the framebuffer; this is an issue to be dealt with in coreboot (the upstream provider) and not libreboot (the downstream provider)).
</p>
<h2><u>*</u> T60 15.4" (1280x800 and 1680x1050) with Intel GPU is <u>UNTESTED</u></h2>
<p>
T60 15.4" (1280x800 and 1680x1050) with Intel GPU is untested in this pre-release. Not much yet is known about panel names.
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>
<h2><u>**</u> Warning: MacBook2,1 <u>UNTESTED</u>!</h2>
<p>
At the time of this pre-release, MacBook2,1 support is present but untested. I have ordered a MacBook2,1
but it has not yet arrived at the time of writing.
I take it merely on faith that these images even work at all. <b>Use at your own risk!</b>
</p>

<h2>Machines no longer supported (compared to previous release):</h2>
<ul>
<li><b>All previous machines still supported!</b></li>
</ul>
<h2>Development notes</h2>
<ul>

with those it is possible to run 'git diff' which shows the changes made in the form
of a patch (diff format); this includes the blobs that were deleted during deblobbing.

<h2>Development notes</h2>
<ul>
<li>
Binary archive now have 2 images:
<ul>
<li>With serial output enabled and memtest86+ included (debug level 8 in coreboot)</li>
<li>With serial output disabled and memtest86+ excluded (faster boot speeds) (debugging disabled)</li>
</ul>
</li>
<li>
Reduced impact on battery life:
<ul>
<li>'processor.max_cstate=2' instead of 'idle=halt' for booting default kernel</li>
</ul>
</li>
<li>
coreboot.rom (faster boot speeds, debugging disabled):
<ul>
<li>Disabled coreboot serial output (Console-> in "make menuconfig")</li>
<li>Set coreboot debug level to 0 instead of 8 (Console-> in "make menuconfig")</li>
<li>Changed GRUB timeout to 1 second instead of 2 (in grub.cfg</li>
<li>Removed background image in GRUB.</li>
<li>Removed memtest86+ payload (since it relies on serial output)
</ul>
</li>
<li>
coreboot_serial.rom (slower boot speeds, debugging enabled):
<ul>
<li>Boot time still reduced, but only by ~2 seconds</li>
<li>has the memtest86+ payload included in the ROM</li>
<li>has serial port enabled. How this is achieved (from X60_source): Turn on debugging level to 8, and enable serial output</li>
</ul>
</li>

</ul>
<h2>Development notes</h2>
<ul>
<li>Removed SeaBIOS (redundant)</li>
<li>
New GRUB version (2.02~beta2)
<ul>
<li>Fixes some USB issues</li>
<li>Includes ISOLINUX/SYSLINUX parser</li>
</ul>
</li>
<li>New grub.cfg</li>
<li>
Removed useless options:
<ul>
<li>options for booting sda 2/3/4</li>
<li>seabios boot option</li>
</ul>
</li>
<li>
Added new menu entries:
<ul>
<li>Parse ISOLINUX config (USB)</li>
<li>Parse ISOLINUX config (CD)</li>
<li>Added 'cat' module for use on GRUB command line.</li>
</ul>
</li>
<li>"set pager=1" is set in grub.cfg, for less-like functionality</li>
</ul>
<p>
The "Parse" options read ./isolinux/isolinux.cfg on a CD or USB,
and automatically converts it to a grub config and switches to the boot menu of that distro.
This makes booting ISO's *much* easier than before.
