    Thank you. I've been reading the first addition. is there a second?
    the second chapter has a very good explanation of paging and how linear
    addresses are used. logical addresses on the other hand are barely
    mentioned. Segmentation is described well, but the translation of
    logical into linear addresses is not described.

    I've read elsewhere that logical addresses are comprised of a 16-bit
    segment selector and a 32-bit offset. I thought pointers were always
    exactly 32-bits (on 32-bit intel). where is the 16-bit selector?

    Thanks again.
