MEM 0080h:0000h - 80286 CPU(Central Processing Unit) The microprocessor which executes programs on your computer. - LOADALL WORKSPACE Size: 102 BYTEs Desc: on the 80286 (unlike 80386), the state buffer from which the LOADALL instruction loads all internal registers is hardwired to physical address 000800h Note: several versions 3.x of MS-DOS leave an empty space at offset 100h in IO.SYS (which is loaded at 0070h:0000h) so that HIMEM.SYS can use LOADALL on 80286 machines without having to save/restore the area of memory that LOADALL uses SeeAlso: MEM 0070h:0100h
