ERRATA

1. Audio Driver Creates a Popping Noise During Operating System
Startup
P :
The audio jack-sensing feature requires reading the impedance of the device connected to the
ROBLEM
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.
I :
A popping noise from the speakers may be heard at the end of the operating system startup
MPLICATION
tune, while loading Microsoft Windows operating systems.
W :
None.
ORKAROUND
S :
This erratum will not be fixed.
TATUS
2. Front Panel Audio Connector Signals Routed Incorrectly
P :
The front panel audio connector pin definition is not correct. Pin 4 is defined as +5 V and should
ROBLEM
be ground. Pin 7 is defined as ground and should be +5V.
I :
Front panel audio cards that route their +5 V rail to Pin 4 will not function correctly.
MPLICATION
W :
Front panel audio cards that require +5 V should route the +5 V rail to Pin 7.
ORKAROUND
S :
This erratum may be fixed in a future hardware revision.
TATUS
3. PCI Slot 1 Cannot be Used With Long PCI Add-in Cards
P :
A tall capacitor is located 3 ¼ inches behind PCI slot 1.
ROBLEM
I :
PCI cards conforming to the PCI specification but exceed 8 inches in length, may not be
MPLICATION
useable in PCI slot 1.
W :
None.
ORKAROUND
S :
This erratum may be fixed in a future hardware revision.
