Thanks Victor.
But wheres the SCL and SDA-Legs of the P24508-Chip on my T61-Board? The Picture of the Alternative Layout dont have it shown?
Thanks much more! Smile

SDA is pin#5, SCL is #6. You may hook the GND on the VGA connector's shell or nuts.

Hi Victor,

Today, my Sortiment of electronic-Parts are achieved me, but they have other specs as on your driven-ic2cprog:

1. I have a MAX232N, i thing its the same!? MAX232A, i couldnt find it! Smile

2. The 2 Diods are SMD's, very small, hmm, ok? Smile

3. My Condensators have 0,15uF, is that ok for MAX232N?

Tomorrow, i try to soldering my Programmer exactly by your driven-ic2cprog-blue-print!! Smile

Hi Slooper,

1. MAX232N is just perfect, made by Texas Instruments and very reliable.
2. If you can solder them then fine.
3. No, MAX232N requires 1uF (one microfarad). I suggest you to use electrolytics: 1uF/50V or similar. Pay attention on C4 and C5 sense:
C4 (+) goes to IC pin#2
C5 (+) goes to circuit GND.

Have fun

Hi Victor, I have a dump-file, but i cant see the password with IBMPassLite

i have a file *.bin with 1.024 Bytes, and the procedure of the 24RF08 has succesfull readed it.

On the Lines i cant read the password:
0x330: U\ W
0x340: U\ W 2 1

What can I do now, is my T61 overdumped Smile

!!?

I would say is TCG/TCPA lock, you may email the dump to support_at_allservice.ro for confirmation.

Hi all,

I thinking about to buy full package PC8394 Tools 1.0d. Has anybody some experiences with this tool (unlocking new models Lenovo ntb + CRC correcting) ? Thanks

Best Regards
Alex

PC8394 tools is the perfect package for models having the embedded secure storage like T43/R52/R60/T60/X60/Z60/Z61.

T61, X61 and up have the old 24RF08/P24S08 eeprom.

Second question is availability new system board scheme where is EEPROM located.

Best Regards

The kit has a manual which includes a pictorial, yes.
