+.SH UUID FORMAT
+There is some ambiguity about how to interpret the UUID fields prior to SMBIOS
+specification version 2.6. There was no mention of byte swapping, and RFC 4122
+says that no byte swapping should be applied by default. However, SMBIOS
+specification version 2.6 (and later) explicitly states that the first 3 fields
+of the UUID should be read as little-endian numbers (byte-swapped).
+Furthermore, it implies that the same was already true for older versions of
+the specification, even though it was not mentioned. In practice, many hardware
+vendors were not byte-swapping the UUID. So, in order to preserve
+compatibility, it was decided to interpret the UUID fields according to RFC
+4122 (no byte swapping) when the SMBIOS version is older than 2.6, and to
+interpret the first 3 fields as little-endian (byte-swapped) when the SMBIOS
+version is 2.6 or later. The Linux kernel follows the same logic.
