BTW, I can see the post code of 0xf8. Does this mean that
coreboot is done booting and its trying to load SeaBIOS?
I see a CPUID request of 0x40000000. I can't see such request
anywhere in coreboot. But there is one in SeaBIOS, to detect
if its running on KVM.

I see that the RIP changes from
   0x7f37827 to 0xf289e

I am not sure where SeaBios jumps and if its the right address.
My coreboot rom size is 512K
