Like the Global Descriptor Table GDT in the entire system, only one interrupt descriptor table IDT. Interrupt descriptor table register IDTR indicates the location of the IDT in memory. Identify 256 interrupt vector number 80386, the maximum length of the IDT is 2K.
Descriptor interrupt descriptor table IDT contained only interrupt gate, trap gate, and task gate. In other words, in protected mode, the 80386 only through interrupt doors, the trap door, or tasks door to transfer to the corresponding interrupt or exception handler.
