Apologies, I should have said X-86-64
IMHO As per your chart
“With the advent of the[u] 32-bit 80386/u processor, the 16-bit general-purpose registers, base registers, index registers, instruction pointer, and FLAGS register, but not the segment registers, were expanded to 32 bits.” Good luck
Your I386 is different architecture, not 64 bit, I can’t help you with this any further.
