 via upgrading the ACPI tables provided by the BIOS with an instrumented,
 modified, more recent version one, or installing brand new ACPI tables.
 
+When building initrd with kernel in a single image, option
+ACPI_TABLE_OVERRIDE_VIA_BUILTIN_INITRD should also be true for this
+feature to work.
+
 For a full list of ACPI tables that can be upgraded/installed, take a look
 at the char *table_sigs[MAX_ACPI_SIGNATURE]; definition in
 drivers/acpi/tables.c.
