IF you have the password then I am sure you verified if that works so you couldn't have the CRC 2 error at that time. Or is about other machine? What model it is? because for this 600e you already have the dump
To correct the error you have to read the eeprom, correct & write back.

The schematic diagrams are coming with the eeprom reader or writer. Just install and look for simple-i2cprog.pdf and driven-i2cprog.pdf.
I hope this will eliminate any confusion for the future.

Thanks ALL SERVICE for your fast answer...
My TP600E is 2646type.
And yes, i read the EEPROM and password but something must be change
when i read that, because when i ingress the password the machine show me OK, and then stop with ERROR188 message(BAD EEPROM CRC#1)
This is because the checksum of the memory and the checksum store in the BIOS are not the same(CRC ERROR)
You are right, i must correct something in the EEPROM but WHAT???(I dont have the original dump)
May be updating the BIOS the checksum store in that will be erased???
Thanks again and sorry for me english...

you said you read the eeprom then you have the dump. This dump is the original eeprom content that must be write into eeprom. CRC error is displayed before the password prompt so you didn't have such error at that time. This error appeared after you successfully unlocked the eeprom and not in the same power cycle. Well you have the dump...
Until you program the eeprom with this dump. you'll not be able to perform any task on your machine (including BIOS update-this will not solve this kind of problems).

Sorry, first of all the machine show me 188, then go on and display the
password prompt(I ingress that and show me OK) and then(other screen) the machine stop witch 188ERROR.
I dont understand one thing.....When the machine ask me the password I read the eeprom and get the DUMP...ok!!
You say that I must re-write the eeprom(witch this DUMP) after the machine stop witch 188ERROR???
What program can I use to write?
I use the PonyProg to read....is secure to write???
Thanks AGAIN

If you used PonyProg to read then you need a good dump indeed.

Please, read the entire thread even if is a bit larger now. I already specified here the links where you could get the software. The schematics are coming with the eeprom reader or writer, just install R24rf08 and see the pdfs.
So. visit http://www.serviceforum.lx.ro/viewforum.php?f=12 or http://home.ripway.com/2005-7/365678/

Hello ALL SERVICE ))
My notebook is a tp600e
I build the driven-i2cprog interfase, but when I trie to use your
software(r24rf08 v2.0a) witch /x/d/i, only get:
ERROR: Eeprom not available!
I tire witch the patcher /x/d/i too
If I use the PonyProg can read the 24rf08 and then ibmpass2 to see the
password....Why you software cant read?

You must use spaces between /x /d /i got that?. PonyProg doesn't work with this interface unless you invert the logics for the signals in setup menu ( i bet you knew that). And of course PonyProg cannot read 24rf08 properly, otherwise why are you still asking help in this thread?
To be clear, you must run the reader with parameters:
-Open a console window start > run and type "cmd" or "command" and press <Enter>
- switch to program folder, usualy c:\allservice\24rf08"
with this command:
"cd c:\allservice\24rf08", you should see the prompt "c:\allservice\24rf08>"
-now, type "r24rf08 filename.bin /x /d /i" - for driven-i2c programmer or simply "r24rf08 filename.bin" for SIPROG and pres <Enter>. don't forget to put spaces between parameters like this:
r24rf08<sp>filename.bin<sp>/x<sp>/d<sp>/i
If you are prompted with "eeprom not found" then something is wrong. I am not there to tell you what that might be.

Hi Allservice
I have tried your method of solving SVP password on a TP T21.
I reached the eeprom with the max232 circuit and got a dump file.
But... the dump file contains nothing but zeros.
What is wrong?
Hope you can help me.

Maybe you can PM me with some details. Anyway the main reason seems to be the SDA line that is held Low all the time.

i have a bricked tp r52 and was glad to find out there was a free way to get it all working again.
i bought the parts for the reader and have taken apart the tp, but have not been able to find the location of the atmel chip. the maintenance manual does mention a security chip, but i assume that's not the one i need. i did find the location on the main board of that chip, but it doesn't seem right.
can someone point out to me where i can find the atmel chip on the main board?
any help would be appreciated.

It is a 8 pin eeprom. remove the top cover with keyboard and touch pad. It is just near the intel southbridge chip.
It is marked as "U53" on the PCB if I remember well.
