Part 4: Exploring the Dedicated Use Part of the \( 80 \times 86 \) 's Memory Address Space Here we will determine the contents of a dedicated 80x86 address space. Procedure 1. Change the contents of the DS register to 000016 . 2. Display the contents of addresses \( 0: 0 \) through \( 0: \mathrm{F} \). 3. Dedicated addresses 0:0 through 0:3 store a pointer for the starting address of the service routine for the divide error interrupt. Use the values displayed in step 2 to calculate the physical address corresponding to this pointer 4. The pointer that identifies the starting location of the nonmaskable interrupt (NMR) service routine is held in storage locations \( 0: 8 \) through 0:B. Use the values displayed in step 2 to calculate the physical address represented by this pointer. 5. The overflow interrupt pointer is held at locations 0: 10 through 0: 13 in memory. Using the values displayed in step 2, calculate the physical address represented by this pointer.
