parallel ATA ports if functionality from both SATA and PATA devices is desired (“combined mode”). 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.

IDE HDD
The ICH7 IDE controller features one set of interface signals that can be enabled, tri-stated or driven low. The
IDE interfaces of the ICH7 can support several types of data transfers:
-- Programmed I/O (PIO): processor is in control of the data transfer
-- 8237 style DMA: DMA protocol that resembles the DMA on the ISA bus, although it does not use the
8237 in the ICH7. This protocol off loads the processor from moving data. This allows higher transfer
rate of up to 16MB/s
-- Ultra ATA/33/66/100: DMA protocol that redefines signals on the IDE cable to allow both host and
target throttling of data and transfer rates of up to 33/66/100 MB/s
