% T60

Native gpu initialization ('native graphics') which replaces the proprietary VGA Option ROM ('Video BIOS' or 'VBIOS').

To find what LCD panel you have, see: ../misc/#get_edid_panelname.

Some T60s have ATI GPUs, and all T60P laptops have ATI GPUs These are incompatible! See #t60_ati_intel for how to remedy this.

Tested LCD panels: working(compatible)

It is unknown whether the 1680x1050 (15.4") and 1920x1200 (15.4") panels use a different inverter board than the 1280x800 panels.

The T60 typically comes with an Intel wifi chipset which does not work at all without proprietary firmware, and while Lenovo BIOS is running the system will refuse to boot if you replace the card. Fortunately it is very easily replaced; just remove the card and install another one after libreboot is installed. See #recommended_wifi for replacements.

ThinkPad T60 (ATI GPU) and ThinkPad T60 (Intel GPU) differences. {#t60_ati_intel}

If your T60 is a 14.1" or 15.1" model with an ATI GPU, it won't work with libreboot by default but you can replace the motherboard with another T60 motherboard that has an Intel GPU, and then libreboot should work.

As far as I know, 14.1" (Intel GPU) and 15.1" (Intel GPU) T60 motherboards are the same, where 'spacers' are used on the 15.1" T60. In any case, it makes sense to find one that is guaranteed to fit in your chassis.

There is also a 15.4" T60 with Intel GPU.

Note: the T60p laptops all have ATI graphics. The T60p laptops cannot be used with libreboot under any circumstances.

The following T60 motherboard (see area highlighted in white) shows an empty space where the ATI GPU would be (this particular motherboard has an Intel GPU):\ \

The reason that the ATI GPU on T60 is unsupported is due to the VBIOS (Video BIOS) which is non-free. The VBIOS for the Intel GPU on X60/T60 has been reverse engineered, and replaced with Free Software and so will work in libreboot.

The 'Video BIOS' is what initializes graphics.

See: https://en.wikipedia.org/wiki/Video_BIOS.\ In fact, lack of free VBIOS in general is a big problem in coreboot, and is one reason (among others) why many ports for coreboot are unsuitable for libreboot's purpose.

Theoretically, the ThinkPad T60 with ATI GPU can work with libreboot and have ROM images compiled for it, however in practise it would not be usable as a laptop because there would be no visual display at all. That being said, such a configuration is acceptable for use in a 'headless' server setup (with serial and/or ssh console as the display).

% ThinkPad T60: Recovery guide

This section documents how to recover from a bad flash that prevents your ThinkPad T60 from booting.

Brick type 1: bucts not reset. {#bucts_brick}

You still have Lenovo BIOS, or you had libreboot running and you flashed another ROM; and you had bucts 1 set and the ROM wasn't dd'd.* or if Lenovo BIOS was present and libreboot wasn't flashed.\ \ In this case, unbricking is easy: reset BUC.TS to 0 by removing that yellow cmos coin (it's a battery) and putting it back after a minute or two:\ \ \ *Those dd commands should be applied to all newly compiled T60 ROM images (the ROM images in libreboot binary archives already have this applied!):\ dd if=coreboot.rom of=top64k.bin bs=1 skip=\$[\$(stat -c %s coreboot.rom) - 0x10000] count=64k\ dd if=coreboot.rom bs=1 skip=\$[\$(stat -c %s coreboot.rom) - 0x20000] count=64k | hexdump\ dd if=top64k.bin of=coreboot.rom bs=1 seek=\$[\$(stat -c %s coreboot.rom) - 0x20000] count=64k conv=notrunc\ (doing this makes the ROM suitable for use when flashing a system that still has Lenovo BIOS running, using those instructions: http://www.coreboot.org/Board:lenovo/x60/Installation. (it says x60, but instructions for t60 are identical)

bad rom (or user error), system won't boot {#recovery}

In this scenario, you compiled a ROM that had an incorrect configuration, or there is an actual bug preventing your system from booting. Or, maybe, you set BUC.TS to 0 and shut down after first flash while Lenovo BIOS was running. In any case, your system is bricked and will not boot at all.

"Unbricking" means flashing a known-good (working) ROM. The problem: you can't boot the system, making this difficult. In this situation, external hardware (see hardware requirements above) is needed which can flash the SPI chip (where libreboot resides).

Remove those screws and remove the HDD:\

Lift off the palm rest:\

Lift up the keyboard, pull it back a bit, flip it over like that and then disconnect it from the board:\

Gently wedge both sides loose:\

Remove that cable from the position:\

Now remove that bezel. Remove wifi, nvram battery and speaker connector (also remove 56k modem, on the left of wifi):\

Remove those screws:\

Disconnect the power jack:\

Remove nvram battery:\

Disconnect cable (for 56k modem) and disconnect the other cable:\

Disconnect speaker cable:\

Disconnect the other end of the 56k modem cable:\

Make sure you removed it:\

Unscrew those:\

Make sure you removed those:\

Disconnect LCD cable from board:\

Remove those screws then remove the LCD assembly:\

Once again, make sure you removed those:\

Remove the shielding containing the motherboard, then flip it over. Remove these screws, placing them on a steady surface in the same layout as they were in before you removed them. Also, you should mark each screw hole after removing the screw (a permanent marker pen will do), this is so that you have a point of reference when re-assembling the system:\

Now wire up the BBB and the Pomona with your PSU.\ Refer to bbb_setup.html for how to setup the BBB for flashing.\ Note, the guide mentions a 3.3v DC PSU but you don't need this on the T60: if you don't have or don't want to use an external PSU, then make sure not to connect the 3.3v leads mentioned in the guide; instead, connect the AC adapter (the one that normally charges your battery) so that the board has power (but don't boot it up)\ \ Correlate the following with the BBB guide linked above:

POMONA 5250:
===  DVD drive ====
 18              -       - 1
 22              -       - NC               ---- RAM is on this end
 NC              -       - 21
 3.3V (PSU)      -       - 17 - this is pin 1 on the flash chip
===  audio jacks ===
This is how you will connect. Numbers refer to pin numbers on the BBB, on the plugs near the DC jack.

Connect the pomona from the BBB to the flash chip. No pics unfortunately. (use the text diagram above).

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

SSH'd into the BBB:\ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w yourrom.rom

It should be Verifying flash... VERIFIED at the end. If flashrom complains about multiple flash chip definitions detected, then choose one of them following the instructions in the output.

Put those screws back:\

Put it back into lower chassis:\

Attach LCD and insert screws (also, attach the lcd cable to the board):\

Insert those screws:\

On the CPU (and there is another chip south-east to it, sorry forgot to take pic) clean off the old thermal paste (with the alcohol) and apply new (Artic Silver 5 is good, others are good too) you should also clean the heatsink the same way\

Attach the heatsink and install the screws (also, make sure to install the AC jack as highlighted):\

Reinstall that upper bezel:\

Do that:\

Re-attach modem, wifi, (wwan?), and all necessary cables. Sorry, forgot to take pics. Look at previous removal steps to see where they go back to.

Attach keyboard and install nvram battery:\

Place keyboard and (sorry, forgot to take pics) reinstall the palmrest and insert screws on the underside:\

It lives!\

Always stress test ('stress -c 2' and xsensors. below 90C is ok) when replacing cpu paste/heatsink:\
