8)Onboard Audio Setting (AUD-EN) (Audio Models only)

The onboard 6 channel audio chip functions as the primary audio circuit, and may be enabled or disabled with this jumper. The default setting, [1-2], enables the onboard audio chip. Reset the jumper to [2-3], disabling the onboard Audio chip, if using a PCI audio card, or if a primary audio Advanced Communications Riser card is used in the ACR slot. (See page 29, 3.7.3, ACR Slot)

9)USB Device Wake-up (USB01PWR / USB23PWR / USB45PWR)

Set these jumpers to +5V to allow wake up from the S1 sleep state (CPU stopped; RAM refreshed; system running in low power mode). Set to +5VSB to allow wake up from other sleep states. The default setting for the three jumpers is [1-2] to select +5V, since not all computers have the appropriate power supply.

NOTE: This feature requires an ATX power supply that can supply at least 2A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system does not power up. The total current consumed must NOT exceed the power supply capability (+5VSB) for normal working conditions or in sleep mode.
