A.5.140 LOADALL, LOADALL286: Load Processor State
LOADALL ; 0F 07 [386,UNDOC]
LOADALL286 ; 0F 05 [286,UNDOC]
This instruction, in its two different-opcode forms, is apparently
supported on most 286 processors, some 386 and possibly some 486. The
opcode differs between the 286 and the 386.
The function of the instruction is to load all information relating to
the state of the processor out of a block of memory: on the 286, this
block is located implicitly at absolute address 0x800, and on the 386
and 486 it is at [ES:EDI].
