5.2Intel® 31244 PCI-X to Serial ATA Controller

Each of the 31244 chips transmits and receives commands to one of the four Serial ATA channels. Direct Port Access or DPA mode is hard-wired on each of the SATA controllers. DPA mode allows independent control of the SATA devices, allowing multiple disks to be accessed at the same time. Refer to the Intel® 31244 PCI-X to Serial ATA Controller Developer’s Manual (273603) for more information.
