Secondary IDE connector

These connectors are used for all IDE devices, most commonly ATA or UATA66 hard disks.

When connecting the IDE disk drive cables to the IDE disk drive connectors, be sure to maintain pin 1 orientation. Pin 1 is indicated in the graphic. The connectors are also keyed to ensure proper orientation. The primary and secondary IDE controllers are indicated in the graphic.

Note: The customer needs to lift and flip the CD-ROM drive unit to gain access to the IDE drive connections.

Supported hard disk features

  • The motherboard provides two independent synchronous direct memory access (DMA) bus-mastering PCI IDE interfaces that support fast IDE PIO Mode 3, Mode 4, Advanced Technology Attachment Packet Interface (ATAPI), and Ultra Advanced Technology Attachment (UATA) interface devices at speeds of 33/66-megabytes per second.
  • Compliant to ATA 4 and 5 specifications.
  • The motherboard BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes.
  • The BIOS Setup Utility automatically detects the IDE device transfer rate and translation mode.

Normally, programmed I/O operations require a substantial amount of CPU bandwidth. In true multi-tasking operating systems, the CPU bandwidth, which is freed up by using bus-mastering IDE, can be used to complete other tasks while disk transfers occur. When used in conjunction with the appropriate driver, the IDE interface can operate as a PCI master capable of supporting Ultra ATA devices with transfer rates of up to 66-megabytes per second.
