That's the sort of thing we quirk on today, I think (maybe an x86 person could confirm). There is the SMBIOS table (that is the DMI) that is available during before we need thse sort of overrides. It could be implemented but I keep on going back to the valid point that Jan raised: This is a firmware bug!! Thought the other solution is to do what Linux does (SetVirtualAddressMap) which would bypass the firmware bug - by executing these calls after ExitBootServices has been called - and in virtual address mode instead of the 1:1. This is just side-stepping the bug. However the implementation that uses SetVirtualAddressMap crashes right away - so it would need some work, while the quirks are not the case. I will let Jan and Andrew figure out what they want and can spin some patches later on. Ian. ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

I am already booting Xen with console=vga,com1 com1=115200,amt loglvl=all so not sure what else to add. This commit broke booting on just about every server. New master has the fix it in, although there is one further fix ahead of that. Try using bc299d01b925d934219b6e8c29fadcd1f1a9210b which is two ahead of current master. ~Andrew You are correct.

I do have Intel AMT setup with Serial Over LAN working so if its at all possible to get more info over serial I will do that.
