Functional Description
Note:
Table 5-69 lists Chipset SATA Feature support information. Table 5-70 contains
descriptions for the SATA features listed in Table 5-69.
SATA interface transfer rates are independent of UDMA mode settings. SATA interface
transfer rates will operate at the bus’s maximum speed, regardless of the UDMA mode
reported by the SATA device or the system BIOS.
