+ * x86 System Management BIOS prtdiag
+ *
+ * Most modern x86 systems support a System Management BIOS, which is a memory
+ * buffer filled in by the BIOS at boot time that describes the hardware.  This
+ * data format is described by DMTF specification DSP0134 (see http://dmtf.org)
+ * This file implements a rudimentary prtdiag(1M) display using the SMBIOS.
+ * Access to the data is provided by libsmbios: see <sys/smbios.h> for info.
+ *
+ * NOTE: It is important to understand that x86 hardware varies extremely
+ * widely and that the DMTF SMBIOS specification leaves way too much latitude
+ * for implementors, and provides no standardized validation mechanism.  As
+ * such, it is not uncommon to find out-of-spec SMBIOSes or fields that
+ * contain strange and possibly even incorrect information.  As such, this
+ * file should not be extended to report every SMBIOS tidbit or structure in
+ * the spec unless we have good reason to believe it tends to be reliable.
+ *
+ * Similarly, the prtdiag(1M) utility itself should not be used to spit out
+ * every possible bit of x86 configuration data from every possible source;
+ * otherwise this code will become an unmaintainable and untestable disaster.
+ * Extensions to prtdiag should prefer to use more stable kernel mechanisms
+ * that actually discover the true hardware when such subsystems are available,
+ * and should generally limit themselves to commonly needed h/w data.  As such,
+ * extensions to x86 prtdiag should focus on integration with the device tree.
+ *
+ * The prtdiag(1M) utility is for service personnel and system administrators:
+ * it is not your personal ACPI disassembler or CPUID decoder ring.  The
+ * complete SMBIOS data is available from smbdump(1), and other specialized
+ * tools can be created to display the state of other x86 features, especially
+ * when that information is more for kernel developers than box administrators.
