Flashing the T400 with a BeagleBone Black

- -

Initial flashing instructions for T400.

- This guide is for those who want libreboot on their ThinkPad T400 - while they still have the original Lenovo BIOS present. This guide - can also be followed (adapted) if you brick your T400, to know how - to recover. -

- -

- An - - "HMM" (Hardware Maintenance Manual) detailing the process of - [dis]assembly is available for this model. - Be careful when reassembling the laptop as the screws on page 144 - (with title "1130 Keyboard bezel") are swapped and if you follow the - HMM you will punch a hole through the bezel in the upper right corner. -

T400 laptops with libreboot pre-installed

- -

- If you don't want to install libreboot yourself, companies exist that sell these laptops - with libreboot pre-installed, along with a free GNU+Linux distribution. -

- Check the suppliers page for more information. -

- -

Serial port

- -

- EHCI debug might not be needed. It has been reported that the docking station - for this laptop has a serial port, so it might be possible to use that instead. -

- -

A note about CPUs

- ThinkWiki has a list of CPUs - for this system. The Core 2 Duo P8400, P8600 and P8700 are believed to work in libreboot. - The T9600 was confirmed to work, so the T9500/T9550 probably also work. -

- -

Quad-core CPUs

- -

- Incompatible. Do not use. -

- -

A note about GPUs

- -

- Some models have an Intel GPU, while others have both an ATI and an Intel GPU; this - is referred to as "switchable graphics". 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. - On systems with switchable graphics, the Intel GPU is used and the ATI GPU is disabled, so - native graphics initialization works all the same. -

- -

CPU paste required

- -

- See #paste. -

- -

Flash chip size

- -

- Use this to find out:
- # flashrom -p internal -V -

- -

- Back to top of page. -

- -

MAC address

- -

- On the T400, the MAC address for the onboard - gigabit ethernet chipset is stored inside the flash chip, - along with other configuration data. -

- Keep a note of the MAC address before disassembly; this is - very important, because you will need to insert this into - the libreboot ROM image before flashing it. - It will be written in one of these locations: -

- -

- - - -

- -

Initial BBB configuration

- -

- Refer to bbb_setup.html for how to - configure the BBB for flashing. -

- -

- The following shows how to connect clip to the BBB (on the P9 header), for SOIC-16 (clip: Pomona 5252): -

- The procedure -

- -

- Remove all screws, placing them in the order that you removed them:
- - -

- Remove those three screws then remove the rear bezel:
- - - - -

- Remove the speakers:
- - - - - -

- Remove the wifi:
- - -

- Remove this cable:
- - - - - -

- Unroute those antenna wires:
- - - - - -

- Remove the LCD assembly:
- - - - - - - - -

- Disconnect the NVRAM battery:
- -

- Disconnect the fan:
- -

- Unscrew these:
- - - - -

- Unscrew the heatsink, then lift it off:
- - -

- Disconnect the power jack:
- - -

- Loosen this:
- -

- Remove this:
- - - - - -

- Unscrew these:
- - -

- Remove this:
- - -

- Unscrew this:
- -

- Remove the motherboard (the cage is still attached) from - the right hand side, then lift it out:
- - - -

- Remove these screws, placing the screws in the same layout - and marking each screw hole (so that you know what ones - to put the screws back into later): - - - - - - -

- Separate the motherboard:
- - -

- Connect your programmer, then connect GND and 3.3V
- - - - - - -

- A dedicated 3.3V PSU was used to create this guide, but - at ATX PSU is also fine:
- -

- -

- Of course, make sure to turn on your PSU:
- -

- -

- Now, you should be ready to install libreboot. -

- -

- Flashrom binaries for ARM (tested on a BBB) are distributed in libreboot_util. Alternatively, - libreboot also distributes flashrom source code which can be built. -

- Log in as root on your BBB, using the instructions in bbb_setup.html#bbb_access. -

- Test that flashrom works:
- # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512
- In this case, the output was: -

-flashrom v0.9.7-r1854 on Linux 3.8.13-bone47 (armv7l)
-flashrom is free software, get the source code at http://www.flashrom.org
-Calibrating delay loop... OK.
-Found Macronix flash chip "MX25L6405(D)" (8192 kB, SPI) on linux_spi.
-Found Macronix flash chip "MX25L6406E/MX25L6436E" (8192 kB, SPI) on linux_spi.
-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.
-

- How to backup factory.rom (change the -c option as neeed, for your flash chip):
- # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -r factory.rom
- # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -r factory1.rom
- # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -r factory2.rom
- Note: the -c option is not required in libreboot's patched flashrom, because - the redundant flash chip definitions in flashchips.c have been removed.
- Now compare the 3 images:
- # sha512sum factory*.rom
- 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. -

- Follow the instructions at ../hcl/gm45_remove_me.html#ich9gen - to change the MAC address inside the libreboot ROM image, before flashing it. - Although there is a default MAC address inside the ROM image, this is not what you want. Make sure - to always change the MAC address to one that is correct for your system. -

- Now flash it:
- # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w path/to/libreboot/rom/image.rom -V -

- -

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

- Example output from running the command (see above): -

-flashrom v0.9.7-r1854 on Linux 3.8.13-bone47 (armv7l)
-flashrom is free software, get the source code at http://www.flashrom.org
-Calibrating delay loop... OK.
-Found Macronix flash chip "MX25L6405(D)" (8192 kB, SPI) on linux_spi.
-Reading old flash chip contents... done.
-Erasing and writing flash chip... FAILED at 0x00001000! Expected=0xff, Found=0x00, failed byte count from 0x00000000-0x0000ffff: 0xd716
-ERASE FAILED!
-Reading current flash chip contents... done. Looking for another erase function.
-Erase/write done.

Thermal paste (IMPORTANT)

- -

- Because part of this procedure involved removing the heatsink, you will need to apply new paste. - Arctic MX-4 is ok. You will also need isopropyl alcohol and an anti-static cloth to clean with. -

- -

- When re-installing the heatsink, you must first clean off all old paste with the alcohol/cloth. - Then apply new paste. Arctic MX-4 is also much better than the default paste used on these systems. -

- -

- NOTE: the photo above is for illustration purposes only, and does not show how to properly apply the thermal paste. - Other guides online detail the proper application procedure. -

- -

Wifi

- -

- The T400 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 - ../hcl/#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 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. -
