4.13 Chipset
The MITX-430/MITX-440-DVI-2E is designed to use the Intel ICH8M I/O Hub. The ICH8 provides
extensive I/O support. Functions and capabilities are as follows:
 PCI Express Base Specification, supports Revision 1.1.
 PCI Local Bus Specification, supports Revision 2.3 for 33 MHz PCI operations.
 Supports ACPI Power Management Logic.
 Enhanced DMA controller, interrupt controller, and timer functions.
 Integrated serial ATA host controllers with independent DMA operation on up to three
ports.
 Integrated IDE controller supports Ultra ATA100/66/33.
 USB host interface with support for up to ten USB ports, five UHCI host controllers, two
EHCI high-speed USB 2.0 host controllers.
 Integrated 10/100/1000 GbE MAC.
 System Management Bus (SMBus) Specification, Version 2.0 with additional support for
most I2C devices.
 Supports Intel high definition audio.
 Low Pin Count (LPC) interface.
 Supports Serial Peripheral Interface (SPI).
