Libreboot supports the following (refer to the <a href="../release.html">release</a> page):
</p>
<ul>
<li>Apple MacBook1,1 and MacBook2,1: download <b>libreboot_macbook21.tar.xz</b></li>
<li>ThinkPad X60, X60s and X60 Tablet: download <b>libreboot_x60.tar.xz</b></li>
<li>ThinkPad T60: download <b>libreboot_t60.tar.xz</b> (see <a href="../hcl/index.html#supported_t60_list">../hcl/index.html#supported_t60_list</a>)</li>
<li>ThinkPad X200: download <b>libreboot_x200_8mb.tar.xz</b> (8MiB flash chip) or <b>libreboot_x200_4mb.tar.xz</b> (4MiB flash chip) (see <a href="../hcl/x200.html">../hcl/x200.html</a>)</li>
<li>ThinkPad R400: download <b>libreboot_r400_8mb.tar.xz</b> (8MiB flash chip) or <b>libreboot_r400_4mb.tar.xz</b> (4MiB flash chip) (see <a href="../hcl/r400.html">../hcl/r400.html</a>)</li>
<li>ThinkPad T400: download <b>libreboot_t400_8mb.tar.xz</b> (8MiB flash chip) or <b>libreboot_t400_4mb.tar.xz</b> (4MiB flash chip) (see <a href="../hcl/t400.html">../hcl/t400.html</a>)</li>
<li>ThinkPad T500: download <b>libreboot_t500_8mb.tar.xz</b> (8MiB flash chip) or <b>libreboot_t500_4mb.tar.xz</b> (4MiB flash chip) (see <a href="../hcl/t500.html">../hcl/t500.html</a>)</li>
</ul>
<p>
The ROM images in each archive use the following naming convention: <b>boardname_keymap_mode.rom</b>
</p>
<p>
Available <i>modes</i>: <b>vesafb</b> or <b>txtmode</b>. The <i>vesafb</i> ROM images are recommended, in most cases;
<i>txtmode</i> ROM images come with MemTest86+, which requires text-mode instead of the usual framebuffer used
by coreboot native graphics initialization.
</p>
<p>
Keymaps are named appropriate/y according to each keyboard layout
support in GRUB. To learn how these keymaps are created, see
<a href="../grub/index.html#grub_keyboard">../grub/index.html#grub_keyboard</a>
</p>
<h2 id="qemu">QEMU</h2>
<p>
Libreboot comes with ROM images built for QEMU, by default:
</p>
<ul>
<li><b>libreboot_qemu_q35_ich9.tar.xz</b></li>
<li><b>libreboot_qemu_i440fx_piix4.tar.xz</b></li>
</ul>
<p>
Examples of how to use libreboot in QEMU:
</p>
<ul>
<li>$ <b>qemu-system-i386 -M q35 -m 512 -bios qemu_q35_ich9_keymap_mode.rom</b></li>
<li>$ <b>qemu-system-i386 -M pc -m 512 -bios qemu_i440fx_piix4_keymap_mode.rom</b></li>
</ul>
<p>
You can optionally specify the <b>-serial stdio</b> argument, so that QEMU will emulate
a serial terminal on the standard input/output (most likely your terminal emulator or TTY).
</p>
<p>
Other arguments are available for QEMU. The manual will contain more information.
</p>
<p>
On GM45 hardware (with libreboot), make sure that the <i>kvm</i> and <i>kvm_intel</i> kernel modules
are not loaded, when using QEMU.

<h1 id="flashrom">How to update libreboot (if you are already running libreboot or coreboot)</h1>
<p>
On all current targets, updating libreboot can be accomplished without disassembly and,
therefore, without having to externally re-flash using any dedicated hardware. In other words,
you can do everything entirely in software, directly from the OS that is running on your libreboot
system.
</p>
<div class="important">
<p>
<b>If you are using libreboot_src or git, then make sure that you built the sources first (see <a href="../git/index.html#build">../git/index.html#build</a>).</b>
</p>
</div>
<p>
Look at the <a href="#rom">list of ROM images</a> to see which image is compatible with your device.
</p>
<h2>Are you currently running the original, proprietary firmware?</h2>
<p>
If you are currently running the proprietary firmware (not libreboot or coreboot),
then the flashing instructions for your system are going to be different.
</p>
<p>
X60/T60 users running the proprietary firmware should refer to <a href="#flashrom_lenovobios">#flashrom_lenovobios</a>.
MacBook2,1 users running Apple EFI should refer to <a href="#flashrom_macbook21">#flashrom_macbook21</a>
</p>
<p>
X200 users, refer to <a href="x200_external.html">x200_external.html</a>,
R400 users refer to <a href="r400_external.html">r400_external.html</a>,
T400 users refer to <a href="t400_external.html">t400_external.html</a>,
T500 users refer to <a href="t500_external.html">t500_external.html</a>
</p>
<h2>Are you currently running libreboot (or coreboot)?</h2>
<p>
X60/T60 users should be fine with this guide. If you write-protected the flash chip, please refer to
<a href="x60_unbrick.html">x60_unbrick.html</a>, <a href="x60tablet_unbrick.html">x60tablet_unbrick.html</a>
or <a href="t60_unbrick.html">t60_unbrick.html</a>. <i>This probably does not apply to you. Most people
do not write-protect the flash chip, so you probably didn't either.</i>
</p>
<p>
Similarly, it is possible to write-protect the flash chip in coreboot or libreboot on GM45 laptops
(X200/R400/T400/T500). If you did this, then you will need to use the links above for flashing,
treating your laptop as though it currently has the proprietary firmware (because write-protected SPI flash
requires external re-flashing, as is also the case when running the proprietary firmware).
</p>
<p>
If you did not write-protect the flash chip, or it came to you without any write-protection
(<b><i>libreboot does not write-protect the flash chip by default, so this probably applies to you</i></b>),
read on!
</p>
<h2>MAC address on GM45 (X200/R400/T400/T500)</h2>
<p>
<b>Users of the X200/R400/T400/T500 take note:</b> The MAC address for the onboard ethernet chipset
is located inside the flash chip. Libreboot ROM images for these laptops contain a generic MAC
address by default (00:F5:F0:40:71:FE), but this is not what you want.
<i>Make sure to change the MAC address inside the ROM image, before flashing it.
The instructions on <a href="../hcl/gm45_remove_me.html#ich9gen">../hcl/gm45_remove_me.html#ich9gen</a>
show how to do this.</i>
</p>
<p>
It is important that you change the default MAC address, before flashing. It will be printed on a sticker
at the bottom of the laptop, or it will be printed on a sticker next to or underneath the RAM. Alternatively,
and assuming that your current firmware has the correct MAC address in it, you can get it from your OS.
</p>
<h2>All good?</h2>
<p>Excellent! Moving on...</p>
<p>
Download the <i>libreboot_util.tar.xz</i> archive, and extract it. Inside, you will find
a directory called <i>flashrom</i>. This contains statically compiled executable files of
the <i>flashrom</i> utility, which you will use to re-flash your libreboot system.
</p>
<p>
Simply use <i>cd</i> on your terminal, to switch to the <i>libreboot_util</i> directory. Inside,
there is a script called <i>flash</i>, which will detect what CPU architecture you have
(e.g. i686, x86_64) and use the appropriate executable. It is also possible for you to
build these executables from the libreboot source code archives.
</p>
<div class="important">
<p>
How to update the flash chip contents:<br/>
$ <b>sudo ./flash update <a href="#rom">yourrom.rom</a></b>
</p>
</div>
<div class="important">
<p>
Ocassionally, coreboot changes the name of a given board. If flashrom complains about a board mismatch, but
you are sure that you chose the correct ROM image, then run this alternative command:<br/>
$ <b>sudo ./flash forceupdate <a href="#rom">yourrom.rom</a></b>
</p>
</div>
<div class="important">
<p>
You should see <b>"Verifying flash... VERIFIED."</b> written at the end of the flashrom output. <b>Shut down</b>
after you see this, and then boot up again after a few seconds.

<p><b>If you are flashing a Lenovo ThinkPad T60, be sure to read <a href="../hcl/index.html#supported_t60_list">../hcl/index.html#supported_t60_list</a></b></p>

$ <b>sudo ./flash i945lenovo_firstflash <a href="#rom">yourrom.rom</a>.</b>

<div class="important">
<p>
You should see within the output the following:<br/>

<p>
You should also see within the output the following:<br/>
<b>"Flash chip is in an unknown state"</b>, <b>"FAILED"</b> and <b>"DO NOT SHUTDOWN OR REBOOT"</b><br/>
Seeing this means that the operation was a <b>resounding</b> success! <b>DON'T PANIC</b>.
