This record provides information about the 8086

registers/register-pairs: CS and IP, SS and SP, OS, and ES. The purpose of this information is for a loader to set the neccessary reqisters for initiation of execution.

REG·TYP

The REG TYP field provides the reqister/reqister-pair name. It also indicates the type of reqister content specification given in the next field. It has the followinq format:

*********************************

*	,	I	I	I	I		I	,	*
* REGID , Z I Z I Z I						Z I Z I L *
*	I	I	I	I	,		I	I	*

*********************************

Zis are I-bit subfields which indicate that these bits have not currently been assigned a function. These bits are required to be zero.

REGID is a two bit subfield that specifies the na~e of the reqisterslreqister-pairs as follows:

REGID ~~9!§!~~/~~~l.EJ~~=~~!~

o CS and IP

1SS and SP

2OS

3ES

L is a one bit field that indicates whether the REGISTER

CONTENTS field is to be interpreted as a loqical address (L=l) that reauires fixinq up by LINK-8~/LOCATE-8~,or as a pair of base and offset specifications (L=0) appropriate for the initialization of the correspondinq reqister/reqister-pair.
