Quick summary PDF on PCI-X

PDF slideshow about PCI-X, fairly detailed

And the overall PCI-X page that Compaq has

The PCI Sig page had lots of "Member Only" Info, so I just dug the above info off one of the members.

The whole one device on a bus is nice, but I dislike the way it's done with a propritary slot compaired to the others. Why not a network slot, sound slot, and storage slot next? They could all benefit frol their own bus, but noone does it this way. Even the CMR and such slots tie into the PCI bus. And on servers, PCI-ES slots are mainly for SCSI or array controllers, but they are still normal PCI components. (PCI-ES has 3 SCSI connectors routed to the PCI slot to allow for redundancy in controllers without the need to move cables or do duplexing tricks at the back of a hard drive cage).
