We see MSFT (Microsoft) all over the place as well as INTL (Intel ?) --
I suppose this machine may be a Dellio (perhaps HP or Compaq)? or
atleast one that has one of those stickers on the case that says

I believe that indicates that the Microsoft ACPI compiler was used to generate the ACPI tables in the BIOS..
