T61:

P24S08 (8 pin) eeprom is on the back of the board, you may need to consult the T61 Hardware Maintenance Manual if you want to dismantle it.

X61:

This is using a small factor PS08 eeprom (24RF08 clone), its position is below the “M” key. It requires the keyboard, front bezel and the modem sub-board to be taken apart.

I wish to express our gratitude to S. Helie (UK) who helped us with the first X61 works, and last but not least, to S. Cyiako (Sweden) who mailed us a perfect X61 mainboard for the tests.

[Updated]

X300, X301, X200 and X201, X220, X230, X100e, X120e, X121e, X1…done. They use the same 24RF08 clone like the other 61’s (appart from Z61 series that still use TPMs). For X300, the eeprom has alternate connection points located underneath, near the memory socket. X100e has the PS08 mini eeprom like the X61 and X121e features the L08 (same eeprom).

We’ve tested on 2 mainboards and TCPA algo is again different.

Great thanks to V. Rikalovic (Serbia) and M. Yang (USA) for the nice shots.

R400, R500, W500 and W700 - R400 and W500 have the eeprom underneath. For R500 is the same 24RF08 clone located on the upper side of the motherboard, under the PCcard/ExpressCard cage. The board must be removed form the Mg frame and you have to peel the black sticker that covers the area

SL410 & SL510 - Looks like the new SL series switched from AMI to Phoenix FirstBIOS so our old friend (24RF08 - PS08) is back in business once again. R24RF08/W24RF08 is the right software, as usual.
*The older SL400/SL500 still need SPEG programmer to be unlocked.

T420, T420s, T520, T530
All of them use the tiny L08 eeprom. These models have passprase always active, and they require TCPA unlock service and W24RF08. T530 has the eeprom covered by the black stickers
