== Special Notes on Task Switching == * When using <code>JMP</code> for task switches: ** The '''Nested Task (NT)''' flag in the <code>EFLAGS</code> register is '''not set'''. ** The '''previous task link''' in the new TSS is '''not updated'''. ** As a result, you '''cannot return''' to the previous task using the <code>IRET</code> instruction. ** This differs from the <code>CALL</code> instruction, which enables task returns by setting the <code>NT</code> flag and saving task link information.
