Thinkpad X31 security chip ?

[jasko]

Hallo,
When I turn on my X31 I listen Four cycles of four short beeps and the screen remains blank.
I read at http://www-307.ibm.com/pc/support/site. ... MIGR-44114
the error is "System board. ( secure chip)".
What can I do to solve this problem ?
1) change the chip (buy a programmed chip)
or do you think there are other solotion?
thanks

Did you ever get that problem solved? I have bought a couple of system boards and have the same problem. Thanks.

Well, I solved my problem - thanks to other links in this forum. The four series of four beeps indicate that the security chip isn't present. That chip is on the IR/IEEE 1394 Firewire daughter card. The chip is paired with the system board so you must use the matching daughter card or you will get an error 0192.

Thanks for this! It took me a lot of head scratching and ram reinsertion before I came across this. I've now got a functioning x31 again!
