+@acronym{ACPI, Advanced Configuration and Power Interface} method provided by
+your computer's firmware, by writing to @file{/proc/acpi/call}. You can pass
+any number of parameters of types @code{ACPI_INTEGER}, @code{ACPI_STRING},
+and @code{ACPI_BUFFER}.
+
+It grants direct and undocumented access to your hardware that may cause damage
+and should be used with caution, especially on untested models.")
