Instruction Set
8.1.4.1
The sreg2 field (Table 8-11) is a 2-bit field that allows one
of the four 286-type segment registers to be specified.
8.1.4.2
The sreg3 field (Table 8-12) is 3-bit field that is similar to
the sreg2 field, but allows use of the FS and GS segment
registers.

8.1.5
The s-i-b fields provide scale factor, indexing, and a base
field for address selection. The ss, index, and base fields
are described next.
8.1.5.1
The ss field (Table 8-13) specifies the scale factor used in
the offset mechanism for address calculation. The scale
factor multiplies the index value to provide one of the com-
ponents used to calculate the offset address.
8.1.5.2
The index field (Table 8-14) specifies the index register
used by the offset mechanism for offset address calcula-
tion. When no index register is used (index field = 100), the
ss value must be 00 or the effective address is undefined.
