Micro caches don't work in 4k pages, so what has this to do with anything? I suspect you're thinking of mainframe cache which may work in larger chunks. 4, 16, and 32 byte cache chunks are mentioned by manufacturers, I think someone used 64 bytes, but I haven't got the name. If anyone has an Intel cache controller spec sheet handy, please contribute. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
