Footnotes
The Effective Address (EA) of the memory operand
is computed according to the mod and r/m fields:
if mod
e
11 then r/m is treated as a REG field
if mod
e
00 then DISP
e
0
*
, disp-low and disp-high
are absent
if mod
e
01 then DISP
e
disp-low sign-extended to
16 bits, disp-high is absent
if mod
e
10 then DISP
e
disp-high: disp-low

The physical addresses of all operands addressed
by the BP register are computed using the SS seg-
ment register. The physical addresses of the desti-
nation operands of the string primitive operations
(those addressed by the DI register) are computed
using the ES segment, which may not be overridden.
