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.

Thanks,
TSC

One of the writers says BIOS problem or memory, but I'm not familiar with it.

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.
