Intel Instruction Set - LES

LES - Load Pointer Using ES
 Usage: LES dest,src
 Modifies flags: None
 Loads 32-bit pointer from memory source to destination register
 and ES. The offset is placed in the destination register and the
 segment is placed in ES. To use this instruction the word at the
 lower memory address must contain the offset and the word at the
 higher address must contain the segment. This simplifies the loading
 of far pointers from the stack and the interrupt vector table.
