Found a nice page with details of all the nifty things in the new opteron:

Chip Architect: Detailed Architecture of AMD's Opteron
Haven't had the time to read it yet but looks interesting...

edit: The board seems to have some problems with the URL, it adds a space between the host and relative URL somehow.. The URL is:

thanks for the information.

anyway, when they release a new 64bit computer, i'd like to make my own 64bit operating system working on 64bit AMD cpu.
so i want to know the newer computer system is whether still compatible with 32bit machine or not. (like IO-BUS and their numbering)
d'you guys have these information? 64bit PC-SPEC or something.

thankyou for reading.
regards.
