Webcontains SS, ESP, EFLAGS, CS, EIP where EIP pointing to the address of the user code to be executed is at the very top. CS and SS point to user code and data entries of GDT, ESP points to the top of the user stack, EFLAGS is initialized with IF = 1 to enable interrupts. DS is set to point to the user data entry in GDT. Then iret is executed. 4 pts WebYou may be eligible for a tax-free Economic Impact Payment (EIP).
