Hi,
First check with the manufacturer for any needed BIOS update prior to
installing SP1. A message about acpi.sys can be an indicator of an issue
with the system BIOS instruction set not being fully compliant with current
standards (they change with time, so even newer machines can have outdated
BIOS').
