Troubleshooting
Question: Do I need the CD that came with your motherboard?
Answer: The supplied compact disc has quite a few drivers and programs
that will greatly enhance your system. We recommend that you review the
CD and install the applications you need. Applications on the CD include
840 chipset drivers for Windows and security and audio drivers.
Question: Why can't I turn off the power using the momentary
power on/off switch?
Answer: The instant power off function is controlled in BIOS by the Power
Button Mode setting. When the On/Off feature is enabled, the motherboard
will have instant off capabilities as long as the BIOS has control of the
system. When the Standby or Suspend feature is enabled or when the
BIOS is not in control such as during memory count (the first screen that
appears when the system is turned on), the momentary on/off switch must
be held for more than four seconds to shut down the system. This feature
is required to implement the ACPI features on the motherboard.
Question: I see some of my PCI devices sharing IRQs, but the sys-
tem seems to be fine. Is this correct or not?
Answer: Some PCI Bus Mastering devices can share IRQs without perfor-
mance penalties. These devices are designed to work correctly while shar-
ing IRQs. See Table 3-1 below for details on shared IRQs.
