H - Parallel ATA IDE Connector
Part Number: 4006188RECS 945GCT-M3 Motherboard

Parallel ATA IDE connector This is the Parallel ATA IDE interface connector. Connect the data cable for an IDE hard drive or ATAPI devices, such as CD-ROM drives, and ATA devices using the transfer modes to this connector. The Parallel ATA IDE 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/sec.
  • Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec.
  • ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible.
  • ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH6's ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.
