I tried what you said and I can see the following:


6: 00000000ff000000 - 0000000100000000 = 2 RESERVED
d addr=0x00007000 len=89000

coreboot-4.0-1929-g79cfe7e-dirty Thu Jan  5 17:41:55 CET 2012 starting...


Debug level of SeaBIOS is set to 10.

How can we guess which thing is causing the problem?

Thank you.

Best regards,
