help with acpi on nforce

I have been to the how-to site giving on the list before, but I have a 
problem I could not find answers to.  Here is a copy of what I get:

barton# iasl -d epox.asl

Intel ACPI Component Architecture
ASL Optimizing Compiler / AML Disassembler version 20040311 [Mar 26 2004]

Loading Acpi table from file epox.asl
 tbutils-0221: *** Warning: Invalid table signature found: [/*
 ]
Table header is invalid!
Couldn't get table from the file
barton#

Does anyone have a acpidump from a nforce2 product that has good headers 
I could try?  I'll post my asl file if anyone would like to take a look 
at it.
