The hardware is home-built with an ASUS M3N78-VM motherboard and an Athlon X2
6000 3.1G CPU running an x86_64 OS.
I ran the following commands per the instructions at
http://www.lesswatts.org/projects/acpi/overridingDSDT.php with the following
results:
=====================
desktop:~ # cp /proc/acpi/dsdt DSDT
desktop:~ # acpidump > acpidump.out
Wrong checksum for OEMB!
desktop:~ # acpixtract DSDT acpidump > DSDT.dat
desktop:~ # iasl -d DSDT.dat
Intel ACPI Component Architecture
AML Disassembler version 20081031 [Dec 3 2008]
Copyright (C) 2000 - 2008 Intel Corporation
Supports ACPI Specification Revision 3.0a
Loading Acpi table from file DSDT.dat
TableHeader length [0x62617420] greater than the input file size [0x35]
Could not get table from the file
==================
Do the messages indicate a BIOS problem? I have not updated for some time, and
would rather not do so unless necessary.
Should I attach the files DSDT.dat, acpidump.out, or DSDT?
