That must be very old because I didn't know AMD made Intel pin compatible processors .

QNX4 doesn't care about processor model/brand.  There is nothing to change in fact there is nothing that can be changed 
;-)

 If so, can someone let me know which files I need to replace?

Socket A is AMD only,  I couldn't have been an Intel CPU in the first place.

Why was the CPU changed in the first place, sounds to me like you have a hardware problem which is causing Fsys to crash
.

Fsys means it QNX4.  A more appropriate forum is : http://community.qnx.com/sf/discussion/do/listTopics/projects.
