| 1. A method for relocating system management interface code in an information handling system comprising:
extracting a relocation table from the system management interface code;
inserting a relocation identifier in each entry of the system management interface code having an address;
searching the system management code for the relocation identifier during execution of the information handling system;
inserting an address based upon a relocation address for each entry in the system management interface code having a relocation
identifier;
generating exception information for entries of the system management interface code containing information corresponding
to the relocation identifier where the entries are not entries needing relocation;
scanning entries of the system management interface code to determine a sequence of bits occurring least frequently within
the entries of the system management interface code; and,
using a least frequently occurring sequence of bits for the relocation identifier.
