Processor Information: Intel: Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz
RAM: 32G

Summary: FWTS https://wiki.ubuntu.com/Kernel/Reference/fwts/dmi_decode
High failures: 2
 dmi_decode: Out of range string index 0x04 while accessing entry 'Processor Information (Type 4)' @ 0x000eb3ea, field 'Serial Number', offset 0x20
 dmi_decode: Out of range string index 0x04 while accessing entry 'Processor Information (Type 4)' @ 0x000eb4b9, field 'Serial Number', offset 0x20

Medium failures: 1
 dmi_decode: String index 0x01 in table entry 'OEM Strings (Type 11)' @ 0x000eb7b0, field 'String 1', offset 0x04 has a default value 'To Be Filled By O.E.M.' and probably has not been updated by the BIOS vendor.

Steps to reproduce:
sudo fwts dmi_decode -
..runs the test on your machine and dumps the output to stdout.
OR
sudo fwts dmi_decode
..runs the test on your machine and appends the output to results.log.

ADVICE: DMI strings are stored in a manner that uses a special index to fetch the Nth string from
the data. For this particular DMI string the index given is not in range which means this particular
entry is broken. The Linux kernel does not use this string, so this error will not cause any system
errors.

ADVICE: It may be worth checking against section 7.5 of the System Management BIOS (SMBIOS)
Reference Specification (see http://www.dmtf.org/standards/smbios).

has not been updated by the BIOS vendor.

ADVICE: The DMI table contains data which is clearly been left in a default setting and not been
configured for this machine. Somebody has probably forgotten to define this field and it basically
means this field is effectively useless. Note that the kernel uses this field so it probably should
be corrected to ensure the kernel is using sane values.

ADVICE: It may be worth checking against section 7.12 of the System Management BIOS (SMBIOS)
Reference Specification (see http://www.dmtf.org/standards/smbios).

[Keng-Yu Lin (lexical)]

For this error:

 dmi_decode: Out of range string index 0x04 while accessing entry 'Processor Information (Type 4)' @ 0x000eb3ea, field 'Serial Number', offset 0x20
 dmi_decode: Out of range string index 0x04 while accessing entry 'Processor Information (Type 4)' @ 0x000eb4b9, field 'Serial Number', offset 0x20

The string is not used by Linux kernel, so newer version of fwts has marked this error as "low failures".

For this one:

Medium failures: 1
 dmi_decode: String index 0x01 in table entry 'OEM Strings (Type 11)' @ 0x000eb7b0, field 'String 1', offset 0x04 has a default value 'To Be Filled By O.E.M.' and probably has not been updated by the BIOS vendor.

This means the field with the content of "To Be Filled By O.E.M."
