<h1 id="rom">Information about libreboot ROM images</h1>
<p>
Libreboot distributes pre-compiled ROM images, built from the libreboot source code.
These images are provided for user convenience, so that they don't have
to build anything from source on their own.
</p>
<p>
The ROM images in each archive use the following at the end of the file name,
if they are built with the GRUB payload: <b>_<i>keymap</i>_<i>mode</i>.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>
<i>keymap</i> can be one of several keymaps that keyboard supports (there are quite a few),
which affects the keyboard layout configuration that is used in GRUB. It doesn't matter
which ROM image you choose here, as far as the keymap in GNU+Linux is concerned.
</p>
<p>
Keymaps are named appropriately according to each keyboard layout
support in GRUB. To learn how these keymaps are created, see
<a href="../grub/#grub_keyboard">../grub/#grub_keyboard</a>
</p>
<h2 id="qemu">QEMU</h2>
<p>
Libreboot comes with ROM images built for QEMU, by default:
</p>
<p>
Examples of how to use libreboot ROM images 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.

<div class="section">
<h1 id="flashrom">How to update or install 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/#build">../git/#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>ASUS KFSN4-DRE?</h2>
<p>
Internal flashing should work just fine, even if you are
currently booting the proprietary firmware.
</p>
<p>
Libreboot currently lacks documentation for externally
re-flashing an LPC flash chip. However, these boards have
the flash chip inside of a PLCC socket, and it is possible
to hot-swap the chips. If you want to back up your
known-working image, simply hot-swap the chip for one that
is the same capacity, after having dumped a copy of the
current firmware (flashrom -p internal -r yourchosenname.rom),
and then flash that chip with the known-working image.
Check whether the system still boots, and if it does, then
it should be safe to flash the new image (because you now
have a backup of the old image).
</p>
<p>
Keeping at least one spare LPC PLCC chip with working firmware
on it is highly recommended, in case of bricks.
</p>
<p>
<b>
DO NOT hot-swap the chip with your bare hands. Use a PLCC
chip extractor. These can be found online.
See <a href="http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools">http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools</a>
</b>
</p>
<p>
Do check the HCL entry: <a href="../hcl/kfsn4-dre.html">../hcl/kfsn4-dre.html</a>
</p>
<h2>ASUS KGPE-D16?</h2>
<p>
If you have the proprietary BIOS, you need to flash libreboot externally.
See <a href="kgpe-d16.html">kgpe-d16.html</a>.
</p>
<p>
If you already have coreboot or libreboot installed, without write protection on the flash
chip, then you can do it in software (otherwise, see link above).
</p>
<p>
<b>
DO NOT hot-swap the chip with your bare hands. Use a PDIP-8
chip extractor. These can be found online.
See <a href="http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools">http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools</a>
</b>
</p>
<p>
Do check the HCL entry: <a href="../hcl/kgpe-d16.html">../hcl/kgpe-d16.html</a>
</p>
<h2>ASUS KCMA-D8?</h2>
<p>
If you have the proprietary BIOS, you need to flash libreboot externally.
See <a href="kgpe-d16.html">kcma-d8.html</a>.
</p>
<p>
If you already have coreboot or libreboot installed, without write protection on the flash
chip, then you can do it in software (otherwise, see link above).
</p>
<p>
<b>

<p>
Do check the HCL entry: <a href="../hcl/kcma-d8.html">../hcl/kcma-d8.html</a>
</p>
<h2>Intel D945GCLF?</h2>
<p>
If you're running the original Intel factory BIOS, then you will need to flash externally.
For instructions on how to do that, refer to <a href="d945gclf.html">d945gclf.html</a>.
</p>
<p>
Otherwise, read the generic instructions below for using the <em>flash</em> script.
</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>Apple iMac 5,2?</h2>
<p>
Internal flashing works, even when flashing from Apple EFI to libreboot. Continue reading the instructions below.
</p>
<p>
<strong>
NOTE: If you're flashing an older version of Libreboot,
the iMac5,2 motherboard is compatible with the MacBook2,1.
Simply flash a MacBook2,1 ROM image, and it should work.
</strong>
</p>
<h2>Flash chip size</h2>
<p>
Use this to find out:<br/>
# <b>dmidecode | grep ROM\ Size</b>
</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.

do this: <em>rm -f patch && wget -O flash https://notabug.org/vimuser/libreboot/raw/9d850543ad90b72e0e333c98075530b31e5d23f1/flash && chmod +x flash</em>
</b>
</p>
<p>
The first half of the procedure is as follows:<br/>
$ <b>sudo ./flash i945lenovo_firstflash <a href="#rom">yourrom.rom</a>.</b>
</p>
</div>
<div class="important">
<p>
You should see within the output the following:<br/>
<b>"Updated BUC.TS=1 - 64kb address ranges at 0xFFFE0000 and 0xFFFF0000 are swapped"</b>.
</p>
<p>
You should also see within the output the following:<br/>
<b>"Your flash chip is in an unknown state"</b>, <b>"FAILED"</b> and <b>"DO NOT REBOOT OR POWEROFF"</b><br/>
Seeing this means that the operation was a <b>resounding</b> success! <b>DON'T PANIC</b>.
</p>
<p>
See this link for more details:
<a href="http://thread.gmane.org/gmane.linux.bios.flashrom/575">http://thread.gmane.org/gmane.linux.bios.flashrom/575</a>.
</p>
<p>
If the above is what you see, then <b>SHUT DOWN</b>. Wait a few seconds, and then boot; libreboot is running, but there is a 2nd procedure <b>*needed*</b> (see below).
</p>
</div>
<div class="important">
<p>
When you have booted up again, you must also do this:<br/>
$ <b>sudo ./flash i945lenovo_secondflash <a href="#rom">yourrom.rom</a></b>
</p>
<p>
If flashing fails at this stage, try the following:<br/>
$ <b>sudo ./flashrom/i686/flashrom -p internal:laptop=force_I_want_a_brick -w <a href="#rom">yourrom.rom</a></b>
</p>
</div>
<div class="important">
<p>
You should see within the output the following:<br/>
<b>"Updated BUC.TS=0 - 128kb address range 0xFFFE0000-0xFFFFFFFF is untranslated"</b>
</p>
<p>
You should also see within the output the following:<br/>
<b>"Verifying flash... VERIFIED."</b>
