** Description changed: In Intel specifications (http://download.intel.com/design/processor/manuals/253668.pdf 7.3), we can see: - 8. Saves the state of the current (old) task in the current task’s + 8. Saves the state of the current (old) task in the current task’s TSS. … - 11. Loads the task register with the segment selector and descriptor - for the new task's TSS. + 12. The TSS state is loaded into the processor But, in QEMU code (https://raw.github.com/qemu/QEMU/v1.0/target-i386/op_helper.c :375), the order is reversed: TSS registers & segments loads BEFORE save old task state.
