Note that the 386 and the early 486 processors did not implement the Interrupt Redirection Map. It was first implemented in the Pentium® processor and was then migrated to the later versions of the 486 processor, as well as all subsequent IA32 processors. It is described in “Efficient Handling of the INT Instruction” on page 495.
