Hi AllService, Thanks for your info. I like to build the reader but I can not found MAX232 or MAX232A, I only can get MAX232CPE, can I use it with 1uf Cap instead?

Yes.
MAX232ACPE - 0.1uF
MAX232CPE - 1uF
1uF/50 should be small enough.
Look out for the cap. polarity. C4 and C5 have to match the V- and V+ IC pins:
C4 (+) --> MAX232 pin#2
C5 (+) --> circuit GND

what i can offer in exchange for now is for me to post an illustrated guide for other t40 users! (i.e. the location of eeprom, images of the interfaces built & so on!) |
This would be really helpfull as I need to remove my T40 POP and need the location of te eeprom
Thanks for a great discussion forum

To get access to eeprom, dismantle the keyboard, palmrest and WIFI card if necessary. For T4X, the eeprom is near Intel Soutbridge chip and it is 8 pin ATMEL 24RF08. Exactly under the touchpad buttons if you follow the direction.

|

Hi
Just got a thinkpad A22m
it comes with error 118 every time i boot.
I'm able to get around this error and force the machine boot on my HD, but still it's annoying.
Is there any way to correct the problem, without tearing the computer apart ?

I think the error is 0188- CRC2.
In this case the eeprom content must be fixed and reprogramed with W24RF08.
Sorry, you need to partialy dismantle the laptop to get access there.

Sorry, you are right, Allservice. It is Error 0188.a
But not CRC2, only "Invalid RDIF Serialization Information Area"
As I wrote, it's possible to bypass the error, so i did that and upgraded my bios to newest version.
In the bios it seems like it's possible to clear RDIF, but No.
Before that I had Error 0188 also with CRC2 error, now i only have 0188.a
I had hoped that would help, but I can see that I have to follow your instructions

It is 0188- CRC2, only that the error text has been changed in the new BIOS code.
