Unfortunately, no, I don't know what the BIOS is writing or reading -- we
need whoever wrote the code to tell us that. This error is logged when the
BIOS tries to write data to a port using ACPI Machine Language, which
causes Windows Server 2003 to prevent access to that port.
See the following KB for more info:
317513 Error Message: ACPI BIOS Is Attempting to Write to an Illegal IO Port
http://support.microsoft.com/?id=317513
This is by design as we are now preventing access to ports that some BIOSes
try to write to in the AML. This has been done to help improve the
stability of the OS.
Thanks!
