Hardware

IDE and Auxiliary Interface (J4)

The J4 connector has 100 pins and is used for Primary IDE, Secondary IDE, Ethernet port, RTC/Battery, speaker, power management, SMBus, and power management interfaces.

IDE Ports

•Supports one Primary EIDE channel (Secondary IDE channel not connected)

•Supports EIDE Ultra DMA 33/66/100 in Master Mode

•Master mode PCI supporting EIDE devices

•Supports ATAPI compliant devices including DVD devices

•PIO IDE transfers up to 14 Mbytes/sec

•Bus Master IDE transfers up to 100 Mbps

The standard 40-pin cable pin-outs are listed in Table 3-24 for J3 connector pin reference. The single Primary channel can be routed to the IDE connector on the custom baseboard per the application requirements.
