+ * Vendor Specific: Version Indicator Record
+ *
+ * This record is used to allow determining Firmware
and CPLD revisions for
+ * components in the system. The goal of this record is
to provide a
+ * flexible method to communicate to software and
firmware the revisions
+ * of these components. This record replaces much of
the functionality of
+ * Record Type 193. OEM SMBIOS Record Type 193 was not
scaling well with
+ * the large number of potential CPLD devices, power
management controllers,
+ * etc. This record is flexible such that each instance
of Type 216
+ * defines one firmware component. This record also
includes the string
+ * name for which software should refer to the
component. The record
+ * includes both data bytes to indicate the revision
and a string value. A
+ * firmware component can implement either or both. If
both are supported,
+ * it allows easy display of the revision, but prevents
the need for
+ * software/firmware to parse strings when doing
comparisons on revisions.
+ * As there is one Type 216 Record per firmware
component, the Handle for
+ * the Record can be used to tie firmware components
with other OEM SMBIOS
+ * Records in the future if needed (similar to how
SMBIOS Type 17 is tied
+ * to other Record Types related to DIMMs)
