Intel® Desktop Board D865PERL Specification Update ERRATA 1. Audio Driver Creates a Popping Noise During Operating System Startup PROBLEM: The audio jack-sensing feature requires reading the impedance of the device connected to the audio jack. A voltage is needed so a current can be measured, and the impedance is derived from the voltage and current. The application of the voltage results in a popping noise that is emitted from the speakers. IMPLICATION: A popping noise from the speakers may be heard at the end of the operating system startup tune, while loading Microsoft Windows operating systems. WORKAROUND: None. STATUS: This erratum will not be fixed. 2. Front Panel Audio Connector Signals Routed Incorrectly PROBLEM: The front panel audio connector pin definition is not correct. Pin 4 is defined as +5 V and should be ground. Pin 7 is defined as ground and should be +5V. IMPLICATION: Front panel audio cards that route their +5 V rail to Pin 4 will not function correctly. WORKAROUND: Front panel audio cards that require +5 V should route the +5 V rail to Pin 7. STATUS: This erratum may be fixed in a future hardware revision. 3. PCI Slot 1 Cannot be Used With Long PCI Add-in Cards PROBLEM: A tall capacitor is located 3 ¼ inches behind PCI slot 1. IMPLICATION: PCI cards conforming to the PCI specification but exceed 8 inches in length, may not be useable in PCI slot 1. WORKAROUND: None. STATUS: This erratum may be fixed in a future hardware revision. 12
