Explanation of test results

Certain test results may require a little more explanation. This section will try and give some context to specific test failures.

Error ID

Explanation

NoSMBIOSorDMIentry

No SMBIOS or DMI entry points found. Best to check SMBIOS entry points with the fwts smbios test.

DMIBadStructCount

Wrong DMI structures count. Could be a mis-configured DMI table

DMIBadStructLength

Bad DMI structure size.

DMIOutOfSpec

A value is outside of the valid values allowed in the specification.

DMIBadIndex

A DMI string is not correctly terminated.

DMIChecksum

Bad DMI structure checksum.

DMIAssetTag

A DMI Asset Tag has been left as the default 1234567890 and should have been defined.

DMIUUID

A DMI UUID has been left as the default 0A0A0A0A-0A0A-0A0A-0A0A-0A0A0A0A0A0A and should have been defined.

DMIBadDefault

A DMI field has been left as the default 'To Be Filled By O.E.M.' and should have been defined.

DMIInvalidHardwareEntry

A DMI device definition does not match to actual hardware.
