- for this system. The Core 2 Duo P8400, P8600 and P8700 are believed to work in libreboot.
- The Core 2 Duo T9600 was confirmed to work (on a different laptop, but still GM45), so the T9400 probably also works.

- <h1>A note about GPUs</h1>
-
- <p>
- <a href="http://www.thinkwiki.org/wiki/Category:R500">ThinkWiki</a> lists
- two possible GPUs: Intel or ATI. Only the Intel GPUs work in libreboot; the ATI
- GPUs require a proprietary Video BIOS, and so those are unsupported in libreboot.
- </p>
- <p>
- On other GM45 laptops in libreboot (e.g. T400, T500), so-called <i>switchable graphics</i>
- is used, which means that the laptop will have <b>both</b> an ATI and Intel GPU, or it will
- only have Intel, depending on which variation you have. On the systems with ATI and Intel,
- you can disable the ATI GPU and use only the Intel GPU, which works in libreboot.
- </p>
- <div class="important">
- <p>
- <b>
- It is unknown whether R500 laptops with an ATI GPU still have an Intel GPU, where you could
- disable the ATI GPU and use the Intel GPU. These are budget laptops, so it's highly likely
- that Lenovo decided on this model to ship with one GPU or the other, but not both (GPUs cost money).
- </b>
- </p>
- <p>
- <b>
- It is **HIGHLY** recommended, when ordering an R500 laptop, to **ENSURE** that the
- one you're ordering has an Intel GPU.

-Found Macronix flash chip "MX25L6445E/MX25L6473E" (8192 kB, SPI) on linux_spi.
-Multiple flash chip definitions match the detected chip(s): "MX25L6405(D)", "MX25L6406E/MX25L6436E", "MX25L6445E/MX25L6473E"
-Please specify which chip definition to use with the -c <chipname> option.
-</pre>
- <p>
- How to backup factory.rom (change the -c option as neeed, for your flash chip):<br/>
- # <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -r factory.rom</b><br/>
- # <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -r factory1.rom</b><br/>
- # <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -r factory2.rom</b><br/>
- Note: the <b>-c</b> option is not required in libreboot's patched flashrom, because
- the redundant flash chip definitions in <i>flashchips.c</i> have been removed.<br/>
- Now compare the 3 images:<br/>
- # <b>sha512sum factory*.rom</b><br/>
- If the hashes match, then just copy one of them (the factory.rom) to a safe place (on a drive connected to another system, not
- the BBB). This is useful for reverse engineering work, if there is a desirable behaviour in the original firmware
- that could be replicated in coreboot and libreboot.
- </p>
- <p>
- Now flash it:<br/>
- # <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w path/to/libreboot/rom/image.rom -V</b>
- </p>

- You might see errors, but if it says <b>Verifying flash... VERIFIED</b> at the end, then it's flashed and should boot.
- If you see errors, try again (and again, and again); the message <b>Chip content is identical to the requested image</b>
- is also an indication of a successful installation.

- <h1>Thermal paste (IMPORTANT)</h1>
-
- <p>
- Because part of this procedure involved removing the heatsink, you will need to apply new paste.
- Arctic Silver 5 is ok. You will also need isopropyl alcohol and an anti-static cloth to clean with.
- </p>
-
- <p>
- When re-installing the heatsink, you must first clean off all old paste with the alcohol/cloth.
- Then apply new paste. AS5 is also much better than the default paste used on these systems.

- The R500 typically comes with an Intel wifi chipset, which does not
- work without proprietary software. For a list of wifi chipsets that
- work without proprietary software, see
- <a href="../hcl/index.html#recommended_wifi">../hcl/index.html#recommended_wifi</a>.
- </p>
-
- <p>
- Some R500 laptops might come with an Atheros chipset, but this is 802.11g only.
- </p>
-
- <p>
- It is recommended that you install a new wifi chipset. This can only
- be done after installing libreboot, because the original firmware has
- a whitelist of approved chips, and it will refuse to boot if you
- use an 'unauthorized' wifi card.
- </p>
-
- <p>
- The following photos show an Atheros AR5B95 being installed, to
- replace the Intel chip that this R500 came with:<br/>

- If you have a WWAN/3G card and/or sim card reader, remove them permanently.
- The WWAN-3G card has proprietary firmware inside; the technology is
- identical to what is used in mobile phones, so it can also track your movements.

- You need DDR3 SODIMM PC3-8500 RAM installed, in matching pairs
