Consider the following scenario: 1. Define address bit of the descriptor so that microprocessor use 64MB of the RAM. 2. By default you can use maximum IMB for any segment (DS/CS/SS/ES) portion of the RAM. 3. You must define lower priority of the descriptor privilege level into access right portion so that segment access will not be granted. 4. Set a bit of access right portion that ensure DS (data segment) has valid address & limit. 5. Also ensure descriptor describes data segment portion. 6. Ensure that data segment can be expand downward if necessary. 7. Define a bit in access right portion that confirm data segment will not be written. 8. Set the requested privilege level of the segment register so that Windows OS operates at application level program. 9. Use a bit to select the global descriptor table. 10. Select only one global descriptor table from the range between 8135 to 8191 through binary bit pattern which you will define. Your task is to define 16 bits of DS register & 64 bits format of the descriptor table that is used for 80386 microprocessor. Also analyze the details of each bit so that above operations will perform correctly.

Transcribed Image Text:Consider the following scenario:
1. Define address bit of the descriptor so that microprocessor use 64MB of the RAM.
2. By default you can use maximum 1MB for any segment (DS/CS/SS/ES) portion of the
RAM.
3. You must define lower priority of the descriptor privilege level into access right portion
so that segment access will not be granted.
4. Set a bit of access right portion that ensure DS (data segment) has valid address & limit.
5. Also ensure descriptor describes data segment portion.
6. Ensure that data segment can be expand downward if necessary.
