@ -61,13 +61,13 @@ Ok, now we know about real mode and memory addressing, let's get back to registe
`CS` register has two parts: the visible segment selector and hidden base address. We know predefined `CS` base and `IP` value, so our logical address will be:
```
0xffff0000:0xfff0
0x0ffff000:0xfff0
```
which we can translate to the physical address:
```python
>>> hex((0xffff000 << 4) + 0xfff0)
>>> hex((0x0ffff000 << 4) + 0xfff0)
'0xfffffff0'
```
