In the *BIOS +setup* program for lenovobios, you can specify that the system will use +one or the other (but not both). + +Libreboot is known to work on systems with only the Intel GPU, using +native graphics initialization.

For a list of wifi chipsets that work +without proprietary software, see +[../hardware/\#recommended\_wifi](../hardware/#recommended_wifi). + +Some T400 laptops might come with an Atheros chipset, but this is +802.11g only. + +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. + +The following photos show an Atheros AR5B95 being installed, to replace +the Intel chip that this T400 came with:\ +  + +WWAN +==== + +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. + +Not to be confused with wifi (wifi is fine). + +Memory +====== + +You need DDR3 SODIMM PC3-8500 RAM installed, in matching pairs +(speed/size). Non-matching pairs won't work. You can also install a +single module (meaning, one of the slots will be empty) in slot 0. + +Make sure that the RAM you buy is the 2Rx8 density. + +[This page](http://www.forum.thinkpads.com/viewtopic.php?p=760721) might +be useful for RAM compatibility info (note: coreboot raminit is +different, so this page might be BS) + +The following photo shows 8GiB (2x4GiB) of RAM installed:\ + + +Boot it! +-------- + +You should see something like this: + +  + +Now [install GNU+Linux](../gnulinux/). + +Copyright © 2015 Leah Rowe <info@minifree.org>\ + +Permission is granted to copy, distribute and/or modify this document +under the terms of the GNU Free Documentation License Version 1.3 or any later +version published by the Free Software Foundation +with no Invariant Sections, no Front Cover Texts, and no Back Cover Texts. +A copy of this license is found in [../fdl-1.3.md](../fdl-1.3.md) |
