The integrated IDE Master/Slave controllers features Dual Independent IDE channels supporting PIO mode
transfers up to 16 Mbytes/sec and Ultra DMA 33/66/100. It provides two separate data paths for the dual IDE
channels that sustain the high data transfer rate in the multitasking environment.
INTEL 82801DBM ICH4-M supports 6 PCI masters and complies with PCI 2.2 specification. It also incorporates
the legacy system I/O like: two 82C37 compatible DMA controllers, Channels 0-3 are hardwired to 8 bit, three
8254 compatible programmable 16-bit counters channels 5-7, hardwired keyboard controller and PS2 mouse
interface(not use in MiTAC 8050 model), Real Time clock with 512Bytes CMOS SRAM and two 82C59
compatible Interrupt controllers. Besides, the I/O APIC managing up to 14 interrupts with both Serial and FSB
interrupt delivery modes is supported.
The integrated power management module incorporates the ACPI 1.0b compliance functions, the APM 1.2
compliance functions, and the PCI bus power management interface spec. v1.1. Numerous power-up events and
power down events are also supported. 21 general purposed I/O pins are provided to give an easy to use logic for
specific application. In addition, the INTEL 82801DBM ICH4-M supports Deeper Sleep power state for Intel
Mobile processor.
A high bandwidth and mature Intel®’ I/O Hub architecture is incorporated to connect Montara and Intel
82801DBM ICH4-M Hub interface together. Intel®’ I/O Hub architecture is developed
