x86 boxes support both segmentation and paging. 

CS:IP = segmented address

After doing the appropriate transformations, you get a linear address.
And once you look up the linear address in a page table, you get
the physical address.

Linear address makes sense even when paging is disabled. If paging
is enabled, linear = virtual.
