1.6.3 
ATA Support 
The board provides five ATA interface connectors: 
•  One PATA connector that supports two devices 
•  Four SATA connectors that support one device per connector 
1.6.3.1 
PATA Interface 
The discrete PATA controller has one bus-mastering PATA interface that is accessible 
through a 44-pin connector.  The PATA interface supports the following modes: 
•  Programmed I/O (PIO):  processor controls data transfer. 
•  8237-style DMA:  DMA offloads the processor, supporting transfer rates of up to 
16 MB/s. 
•  Ultra DMA:  DMA protocol on ATA bus supporting host and target throttling and 
transfer rates of up to 33 MB/s. 
•  ATA-66:  DMA protocol on ATA bus supporting host and target throttling and 
transfer rates of up to 66 MB/s.  ATA-66 protocol is similar to Ultra DMA and is 
device driver compatible. 
•  ATA-100:  DMA protocol on ATA bus allows host and target throttling.  The 
controller’s ATA-100 logic can achieve read transfer rates up to 100 MB/s and write 
transfer rates up to 88 MB/s.   
 
NOTE 
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce 
reflections, noise, and inductive coupling. 
The PATA interface also supports ATAPI devices (such as optical drives) and ATA 
devices using the transfer modes. 
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector 
(ECHS) translation modes.  The drive reports the transfer rate and translation mode to 
the BIOS.
