[10p] b) The selector in (a) points to a segment descriptor starting at address 00100220H in the descriptor table. The words of the descriptor, stored in memory using big endian method, are 00100220H-0110H 00100222H-0000H 00100224H-1A20H 00100226H-0000H I. Draw a memory map indicating the beginning and ending address of the memory segment selected by the descriptor as well as the beginning and ending address of the whole memory. [8P] II. Use the access rights byte to describe how the selected segment functions in the system. [10p] III. What happens after examination of the P bit in the access rights byte? In your description use appropriate terminology. [3p] c) If the current value of IP is 00000226H, what is the physical address of the next instruction to be fetched from the code segment? Comment on the result obtained. [3p]
