Desktop Board Features 
23 
 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. 
Wake from PS/2 Keyboard/Mouse 
PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 or S3 state. 
PME# Wakeup Support 
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, 
or S5 state. 
Speaker  
A speaker is mounted on the desktop board.  The speaker provides audible error code (beep code) 
information during the Power-On Self-Test (POST).  For a list of the beep codes, see Table 38 on 
page 95.
