Hi folks -

Attached is a txt file with output of acpidump for the xw4600.

I also noted that acpidump printed this message to stderr:
Wrong checksum for FADT!

Can any of you tell me what that message implies?

Thanks,
John

Isn't that possible, however, that the BIOS of this new machine is based on an older one that used to have this problem?

Well, John, can you please post the output of acpidump from this machine?

Thanks,
Rafael
