Physical Address - 0x07C00
Logical Address - 0x07c0:0000
When you change from physical address to logical address, you add zero to 16 antilogarithm ( = shift towards left for four times ) then add offset.
0x07C0:0000 Calculation
0x7C00 + 0x0000 = 0x7C00 = 0x07C00
0x2004:0101 Calculation
0x20040 + 0x0101 = 0x20141
