Some 16-bit stuff...
A segment address is bit shifted to the left
by four bits to form a 20-bit physical address
and a 16-bit offset is added to the result to
index into a segment.
So 1234:0100 would create the
physical address 12440
Is this correct???????????
Yep! For REAL mode (16-bit) absolutely true!
A slightly more visual method is..
12340 <-- Seg 1234:0
_0100 <-- Offset 0:0100
---------
12440 <- 1244:0 1240:40 Same physical address!
OR
Seg 1234 + (0100 >> 4)
Seg: 1244 And set offset to 0
