for a <generic> description of it You gan just google with "page frame"
and it will take You to a reasonably good wikipedia article
http://en.wikipedia.org/wiki/Page_tablefor the IBM implementation details You can read the POP ( IE the hardware bible )
or search the IBM redbooks for the ABC of systems programming
all was nicely and thoroughly explained in the IBM System Journal articles on Virtual storage
but ...once they were available for free ,
unfortunately now some IBM droid decided to transfer them to the brigands of IEEE
and You will have to pay 30 ( Thirty ) Dollars for each article
a very intelligent way of <disseminating> the IBM culture
