- <h1 id="bucts_brick">Brick type 1: bucts not reset.</h1>
- <p>
- 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.<br/><br/>
-
- 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:<br/>
- <img src="../images/t60_dev/0006.JPG" alt="" /><br/><br/>
-
- *Those dd commands should be applied to all newly compiled T60 ROM images (the ROM images in libreboot binary archives already have this applied!):<br/>
- dd if=coreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x10000] count=64k<br/>
- dd if=coreboot.rom bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k | hexdump<br/>
- dd if=top64k.bin of=coreboot.rom bs=1 seek=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k conv=notrunc<br/>
- (doing this makes the ROM suitable for use when flashing a machine that still has Lenovo BIOS running,
- using those instructions: <a href="http://www.coreboot.org/Board:lenovo/x60/Installation">http://www.coreboot.org/Board:lenovo/x60/Installation</a>.
- (it says x60, but instructions for t60 are identical)
- </p>
-
- <h1 id="recovery">bad rom (or user error), machine won't boot</h1>
-
- <p>
- In this scenario, you compiled a ROM that had an incorrect configuration, or there is an actual bug preventing your machine 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 machine is bricked and will not boot at all.
- </p>
- <p>
- &quot;Unbricking&quot; means flashing a known-good (working) ROM. The problem: you can't boot the machine, making this difficult. In this situation, external hardware (see hardware requirements above) is needed which can flash the SPI chip (where libreboot resides).

-
- <p>
- Remove those screws and remove the HDD:<br/>

- <p>
- 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 machine:<br/>
