POST error 127, IBM Thinkpad 600X

I replaced the motherboard on an IBM thinkpad 600X and now get the POST error of 127. When I run the internal diagnostics, everything look fine. The documentation from IBM does not describe the error. Does anyone have a clue what the error means so I can determine how to fix it.

One of the writers says BIOS problem or memory, but I'm not familiar with it.
IBM says unspecified system board failure for 1XX codes. T
see if this helps


Also on other systems with an Intel CPU it has been said that it means "With appropriate jumper setting, you will only get a post 127 error if your processor is >166Mhz for Mxx/Axx and <200Mhz for Cxx/Sxx. This error will occur at every bootup, but the system will run fine."  That was taken from a Company that sells Intel chips.

Or you could try this for the thinkpad because I think that has a 500 MHz P3 chip:
 hit esc, esc, and *then* F1 it should load if it does then because you have changed the MOBO then it will give you this every time but should run.
