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.

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.md](bbb_setup.md) 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.
