Memory Map
Table 3-2 provides the common PC/AT memory allocations. These are DOS-level addresses. The OS
typically hides these physical addresses by way of memory management.
I/O Address Map
Table 3-3 provides the I/O address map. These are DOS-level addresses. The OS typically hides these
physical addresses by way of memory management.
