以下机型的密码芯片都是用 P24S08芯片,国外的网站上有介绍,这种芯片可用24RF08的密码编程器来读取。再用IBMPASS 2.1此软件算密码
原文是:We have the confirmation for newer R61, T61 and X61 - added: T400, T500, X300(X200), X301, R400, R500, W500. They don't use a TPM system like R60/X60/T60, they dropped back to P24S08 (24RF08 clone).
For P24S08 you may simply use the free 24RF08 eeprom reader and IBMpass 2.1 lite.
