Determine the offset needed to access physical address 34D36

Determine the offset needed to access physical address 34D36h with each of the following segment selectors: 34 A 4h 32 FFh

Solution

a. The segment selector is: 34A4h: And to access the physical address 34D36h, the offset needed is: 34D36H - 34A4H = 216374₁₀ - 13476₁₀ = 202898₁₀ = 31892H.

b. The segment selector is: 32FFh: And to access the physical address 34D36h, the offset needed is: 34D36H - 32FFH = 216374₁₀ - 13055₁₀ = 203319₁₀ = 31A37H.
