Intel Plans A Common Socket For Xeon, Itanium
stonedonkey writes "According to EE Times, Intel is planning a common system platform for the Xeon and Itanium by 2007, "creating a unified 64-bit motherboard with a new, one-size-fits-all socket." Intel's Jason Waxman says , "It has been something that customers have been asking us for for a while now...the reseller [currently] has to have an inventory of both boxes on hand." Feeling the heat from the competition, cutting losses, or just friendly customer service?"
Dude, Intel's got it's own OpenFirmware like doohickey already for the Itanium, it's called EFI.
Anyway, it's really simple. The processors will assert different "core-type" lines, which will control which ROM is memory-mapped to the default EIP pointer at boot time. I mean, Intel processors already signal their allowed clocking speeds by pins right now. Hell, they're probably different in x86-32 and Itanium, so they could both "be active" all the time, jumping to the appropriate memory-mapped physical address (both of which would be mapped at power-on to their own ROMs) and there'd be no need for an option line.
THIS THING CAN TURN ON A DIME, MACROSSZERO STYLE ALSO FUCK BETA, ~NYORON
