SGDT/SIDT -- Store Global/Interrupt Descriptor Table Register. Opcode Instruction Clocks Description 0F 01 /0 SGDT m 9 Store GDTR to m 0F 01 /1 SIDT m 9 x86 Instruction Set Reference. SGDT 0F 01 /0, SGDT m, Store GDTR to m. SGDT is only useful in operating-system software; however, it can be used in Description. The contents of the descriptor table register is copied by sgdt/sidt to the six bytes of memory specified by the operand. The first word at SGDT - Store Global Descriptor Table (286+ privileged) Usage: SGDT dest Modifies flags: none Stores the Global Descriptor Table (GDT) Register into the Store GDTR to m. * SeeIA-32ArchitectureCompatibilitysectionbelow. Instruction Operand Encoding ¶. Op/En, Operand 1, Operand 2, Operand In IA-32e mode, the operand size is fixed at 8+2 bytes. The instruction stores an 8-byte base and a 2-byte limit. SGDT is useful only by operating-system The SGDT and SIDT instructions are only useful in operating-system software; however, they can be used in application programs without causing an exception The base address of the GDT can be found using the SGDT instruction. You can alter the location of the GDT using the LGDT instruction.
