sorry, i thought about another question about this issue, if intel do not tell us how to run instructions on its cpu and chipset, how could linux run on intel architecture? I'm a newbie, do not know firmware programming very clearly, so ask this silly question here.
thanks!

If you search the archives for my name and "Intel CPU", you should find a patch to support all Intel CPUs as of ~6 months ago, whenever the patch was posted. Unfortunately, not all the microcode updates will fit into the flash of most of the Intel mainboards we support, so some sort of compression needs to be put in place. If you can get it to work, great, I've been tied up with other things as of late.

Hi Corey,
I'm a little confused. We had a discussion in the coreboot IRC room yesterday. We thought that intel do not provide public information on how to initiate and test their chipset, so we are not able to provide support to those intel chipset in coreboot.
Then how could you get the code to initiate and test intel chipset? do intel provide public information about that? I found coreboot only support up to PIII CPUs, does it mean intel only provide chipset initiation code for up to PIII CPUs?
thanks!

They might provide information under NDAs (non-disclosure agreements). Other vendors also do that, but that's okay if someone is willing to sign an NDA and if the NDA allows distribution of the resulting code under the terms of the GPL, maybe after getting clearance from the vendor.
The issue seems to be that intel is less willing to do that than others, and if they are, they seem to move rather slowly.

No, I didn't mean intel chipsets (did I say chipsets? If so, I'm sorry), I meant the CPUs. I've been through the docs enough to check that the current init for P3s will work for all current Intel CPUs, with the exception of having the microcode updates for the newer CPUs. All my patch does is better organize the current CPUs, add the CPU IDs and appropriate socket folders for the newer ones, and add the microcode updates for every PII and newer CPU, including Xeons. Unfortunately, those updates are too large to fit in the rom for some socket types/mainboards currently in the tree, so something needs to be done to make them fit. You'll have to take care of the rest of the chipset yourself ;)
Good luck! -Corey
