Conventional bus resource steering is used.  Native mode is the preferred mode for configurations 
using the Windows* XP and Windows 2000 operating systems.   
 
NOTE 
Many Serial ATA drives use new low-voltage power connectors and require adaptors or power 
supplies equipped with low-voltage power connectors.

1.5.4  Real-Time Clock, CMOS SRAM, and Battery 
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory.  When the computer 
is not plugged into a wall socket, the battery has an estimated life of three years.  When the 
computer is plugged in, the standby current from the power supply extends the life of the battery.  
The clock is accurate to 
± 13 minutes/year at 25 ºC with 3.3 VSB applied. 
 
NOTE 
If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS 
RAM at power-on. 
1.6  PCI Express* Connectors 
The boards provides one PCI Express x1 connector.  The x1 interface supports simultaneous 
transfer speeds up to 500 MBytes/sec. 
The PCI Express interface supports the PCI Conventional bus configuration mechanism so that the 
underlying PCI Express architecture is compatible with PCI Conventional compliant operating 
systems.  Additional features of the PCI Express interface include the following: 
•  Support for the PCI Express enhanced configuration mechanism 
•  Automatic discovery, link training, and initialization 
•  Support for Active State Power Management (ASPM) 
•  SMBus 2.0 support 
•  Wake# signal supporting wake events from ACPI S1, S3, S4, or S5 
•  Software compatible with the PCI Power Management Event (PME) mechanism defined in the 
PCI Power Management Specification Rev. 1.1
