<h1 id="rom">List of ROM images in libreboot</h1>
<p>
Use the list of archives below to know which archive is correct
for your device:
</p>
<ul>
<li>ThinkPad X60, X60s and X60 Tablet: <b>libreboot_x60.tar.xz</b></li>
<li>ThinkPad T60: <b>libreboot_t60.tar.xz</b> (note, see <a href="../hcl/index.html#supported_t60_list">../hcl/index.html#supported_t60_list</a>)</li>
<li>ThinkPad X200: <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: <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>Apple MacBook1,1 and MacBook2,1: <b>libreboot_macbook21.tar.xz</b></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 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>
Coreboot supports <a href="http://www.coreboot.org/QEMU">QEMU</a>. QEMU is useful for testing purposes. Libreboot
comes with ROM images built for QEMU, by default.
</p>
<p>
The following ROM image archives are available in libreboot:
</p>
<ul>
<li>libreboot_qemu_q35_ich9.tar.xz</li>
<li>libreboot_qemu_i440fx_piix4.tar.xz</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 class="lenovobios">
Following this guide means simply flashing a libreboot ROM. This guide will not (directly) teach you how to make a backup (dump) of the original Lenovo BIOS
because to do so would be to explicitly endorse proprietary software. However, for the purposes of reverse engineering it can be useful
to have a backup. Each copy of the original Lenovo BIOS is tied to the specific machine that it came from; it will not run
on any other machine, even if it's the same type of machine as yours. What this means is that, effectively, you can back it up now (so that you can
re-flash it later if you want to run the original Lenovo BIOS again) or lose it forever. The X60/T60 installation
guide on the coreboot wiki will show you how to do this:
<a href="http://www.coreboot.org/Board:lenovo/x60/Installation">http://www.coreboot.org/Board:lenovo/x60/Installation</a>.<br/>
Do not make this decision lightly! This is your last and only chance.
</p>
<p>
The following is for the libreboot image and *not* the factory bios dump:
</p>
<p>
Check the last two 64K regions in your ROM file (libreboot.rom in this example):<br/>
<b>$ dd if=libreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s libreboot.rom) - 0x10000] count=64k</b><br/>
<b>$ dd if=libreboot.rom of=lower64k.bin bs=1 skip=$[$(stat -c %s libreboot.rom) - 0x20000] count=64k</b><br/>
<b>$ sha512sum lower64k.bin top64k.bin</b><br/>
Make *sure* that they match before you continue. The ROMs included pre-compiled in libreboot should already match.
If they don't match, then do this (based on those instructions from <a href="http://www.coreboot.org/Board:lenovo/x60/Installation">coreboot wiki</a>):<br/>
<b>$ dd if=top64k.bin of=libreboot.rom bs=1 seek=$[$(stat -c %s libreboot.rom) - 0x20000] count=64k conv=notrunc</b><br/>
After this, the ROM will be safe to flash. Explanation is provided in <a href="../git/index.html#build_bucts">../git/index.html#build_bucts</a>.
</p>
</div>
<p><b>This is for the ThinkPad X60 and T60 while running Lenovo BIOS. If you already have coreboot or libreboot running,
then go to <a href="#flashrom">#flashrom</a> instead!</b></p>
<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>
<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>"YOURBOARD/YOURROM" should be replaced with what is correct as per <a href="#rom">#rom</a>. Alternatively
you may be using your own custom ROM. Adapt.</p>
<p>
Run the script:<br/>
<b>$ sudo ./flash i945lenovo_firstflash bin/<a href="#rom">YOURBOARD/YOURROM</a>.</b>
</p>
<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>"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>.
</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>
<p>
<b>
If you boot and you see nothing, try turning up the backlight (Fn+Home).
</b>
</p>
<p>
When you have booted up again:<br/>
<b>$ sudo ./flash i945lenovo_secondflash bin/<a href="#rom">YOURBOARD/YOURROM</a></b>
</p>
<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>
</p>
<p>Shut down again, wait a few seconds, and then boot.</p>
</div>
<p>
Some thinkpads come with WWAN cards installed, along with sim cards. These use non-free firmware and should be removed.
You might also want to remove bluetooth. See <a href="../security/x60_security.html">../security/x60_security.html</a> and
<a href="../security/t60_security.html">../security/t60_security.html</a>.

Following this guide means simply flashing a libreboot ROM. This guide will not (directly) teach you how to make a backup (dump) of the original Apple EFI firmware
because to do so would be to explicitly endorse proprietary software. However, for the purposes of reverse engineering it can be useful
to have a backup. Each copy of the original Apple EFI is (believed, but unproven to be) tied to the specific machine that it came from; it will not (as is believed) run
on any other machine, even if it's the same type of machine as yours. What this means is that, effectively, you can back it up now (so that you can
re-flash it later if you want to run the original Apple EFI firmware again) or lose it forever. The macbook21 installation
guide on the coreboot wiki will show you how to do this:
<a href="http://www.coreboot.org/Board:apple/macbook21">http://www.coreboot.org/Board:apple/macbook21</a>.<br/>

<h1 id="flashrom">X60/X60S/X60T/T60/X200/R400/macbook21: How to flash the ROMs onto your machine (if running libreboot or coreboot already)</h1>
<p>
<b>
These instructions work for the Lenovo ThinkPad X60/X60S/X60T/T60 and Apple MacBook2,1.
</b>
</p>
<p>
<b>
This assumes that you already have coreboot or libreboot running.
</b>
</p>
<p>
<b>
If you have Lenovo BIOS running (X60/X60S/X60T/T60), go to <a href="#flashrom_lenovobios">#flashrom_lenovobios</a> instead.
</b>
</p>
<p>
<b>
If you have Lenovo BIOS running (X200), go to <a href="x200_external.html">x200_external.html</a> instead.
</b>
</p>
<p>
<b>
If you have Lenovo BIOS running (R400), go to <a href="r400_external.html">r400_external.html</a> instead.
</b>
</p>
<p>
<b>
If you have Apple EFI firmware running (macbook21), go to <a href="#flashrom_macbook21">#flashrom_macbook21</a> instead.
</b>
</p>
<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>
<p>
<b>
If you have an X200 or R400 with libreboot or coreboot already running, note that
the Gbe in the boot flash contains your MAC address. You will need to change the default
MAC address inside the ROM images before flashing a new libreboot image. See
<a href="../hcl/gm45_remove_me.html#ich9gen">ich9gen</a> for details.
Another important note about the X200/R400: even if you do already have libreboot or coreboot,
it is possible for the user to write-protect regions in the flash chip, by modifying
the flash descriptor. If you have locked regions, you will need an external flasher
(see <a href="x200_external.html">x200_external.html</a> or <a href="x200_external.html">x200_external.html</a>)
to re-flash those regions. By default,
the X200 and R400 ROM images in libreboot contain a descriptor+gbe with all regions unlocked.
</b>
</p>
<p>
<b>
If you are flashing an Apple MacBook2,1, be sure to read the information in <a href="../hcl/index.html#macbook21">../hcl/index.html#macbook21</a>.
</b>
</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 <a href="#rom">#rom</a> to see which ROM is suitable for your machine. Alternative you may be using your own
custom ROM. Adapt.
</p>
<p>
Flash the ROM:<br/>
<b>$ sudo ./flash update bin/<a href="#rom">YOURBOARD/YOURROM</a></b>
</p>
<p>
If you are sure that you are flashing the correct image but you get the error
<b>This coreboot image (LENOVO:ThinkPad X60) does not appear to be correct for the detected mainboard (Lenovo:ThinkPad X60 / X60s / X60t) or
similar (if it's a different board), then do</b>:
<br/>
<b>$ sudo ./flash forceupdate bin/<a href="#rom">YOURBOARD/YOURROM</a></b>
</p>
<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.
