Re: [coreboot] Support to Intel CPUs

[Star Liu]

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!
