4 ETX® connectors

4.6.3Connector X4 Signal Description

IDE Ports

The IDE host adapter is capable of DMA-133 operation and supports only one single IDE channel which is connected to the primary channel of the ETX® connector X4. Per default it is set to DMA-33, to achieve the best compatibility to most baseboard implementations. Implementation information is provided in the ETX® Design Guide. Refer to those documents for additional information.

Configuration:

The IDE host adapter is a PCI bus device. It is configured by the BIOS during PCI device configuration. You can disable it in setup. Resources used by the primary IDE host adapter are compatible with the PC/AT.

Note:	PHOENIX BIOS will not recognize a Slave device on an IDE port if there is no Master device connected to the
	same IDE port. Implementation and limitation information is provided in the ETX® Design Guide from
	document revision 2.1. Refer to the documentation for additional information.

Ethernet

The Ethernet interface is based on the Intel® 82562 Fast Ethernet PCI controller. This 32-bit PCI controller is a fully integrated 10/100BASE-TX LAN solution.

The Ethernet interface requires an external transformer. See the ETX® Design Guide for suggestions on transformer selection.

Configuration:

The Ethernet interface is a PCI device. The BIOS setup automatically configures it during configuration of the PCI device.

Note:	Implementation and limitation information is provided in the ETX® Design Guide from document revision
	2.1. Refer to the documentation for additional information.

Power Control

Power Good / Reset Input:

The ETX®-CD provides an external input for a power-good signal or a manual- reset pushbutton. The implementation of this subsystem complies with the ETX® Specification. Implementation information is provided in the ETX® Design Guide. Refer to the documentation for additional information.

Power Management

ATX PS Control:

The ETX®-CD can control the main power output of an ATX-style power supply. The implementation of this subsystem complies with the ETX® Specification. Implementation information is provided in the ETX® Design Guide. Refer to the documentation for additional information.
