Intel Desktop Board DG33TL Technical Product Specification 
22 
 
1.6.4 
Serial ATA Interfaces 
The board provides five Serial ATA (SATA) connectors, which support one device per 
connector. The board also provides one red-colored external Serial ATA (eSATA) 
connector. 
1.6.4.1 
Serial ATA Support 
The DG33TL Desktop Board’s Serial ATA controller offers six independent Serial ATA 
ports with a theoretical maximum transfer rate of 3 Gbits/sec per port.  One device 
can be installed on each port for a maximum of six Serial ATA devices.  A point-to-
point interface is used for host to device connections, unlike Parallel ATA IDE which 
supports a master/slave configuration and two devices per channel. 
For compatibility, the underlying Serial ATA functionality is transparent to the 
operating system.  The Serial ATA controller can operate in both legacy and native 
modes.  In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 
and 15).  In Native mode, standard PCI Conventional bus resource steering is used.  
Native mode is the preferred mode for configurations using the Windows* XP and 
Windows Vista operating systems.   
 
NOTE 
Many Serial ATA drives use new low-voltage power connectors and require adapters or 
power supplies equipped with low-voltage power connectors.
