4) USB Device Wake-up (USBPWR)
The jumpers are set to +5V as the default to allow wake up from the S1 sleep
state (CPU stopped; RAM refreshed; system running in low power mode) using
the connected USB devices. Set the jumpers to +5VSB to allow wake up from
S3 sleep state (no power to CPU; RAM in slow refresh; power supply in re-
duced power mode). The default setting for the three jumpers is 2-3 to select
+5V (because not all computers have the appropriate power supply to support
the other mode).
NOTES:
1. 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.
2. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal working conditions or in sleep mode.
5) Onboard Audio Setting (ADN) (audio models only)
The onboard Audio Codec may be enabled or disabled using these jumpers.
Disable the onboard Audio Codec if using a PCI audio card on any of the
expansion slots or a primary audio/modem CNR on a CNR slot (see CNR Slot
later in this section).
