CAUTION

Power supplies used with this desktop board must be able to provide enough standby current to

support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby

current necessary to support multiple wake events from the PCI and/or USB buses exceeds power

supply capacity, the desktop board may lose register settings stored in memory.

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

• Resumes operation from either ACPI S1 or ACPI S3 state

• Requires only one call to access the computer

• Detects incoming call similarly for external and internal modems

• Requires modem interrupt be unmasked for correct operation

Wake from USB

USB bus activity wakes the computer from an ACPI S1 or S3 state.

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.
