Learn Something Old Every Day, Part XVIII: How Does FPU Detection Work?

The x86 architecture's FPU detection and interface evolved significantly from the 8086 to the 80386, with the 286 and later CPUs using a generic co-processor interface that was later simplified. The 386 and 486 CPUs took over some of the responsibilities of the original 8087 BIU, with the 386 and 486SX tracking FP instruction/data pointers and validating memory operands, and the 386 and 486SX ...
