Question

Determine the memory location addressed by the following real mode Core2 register combinations: DS = 1A00H and ECX = 00002000H

Answer 1

We are given with Segment Register=1A00H

Therefore Segment address would be found by appending 0H at the end to get it. Therefore the segment address would be 1A000H.

Now to get the memory location we have to add segment register address to the content of the register. Therefore adding 1A00H and 00002000H we get 00001C000H which is the required memory location.
