Intel 5800/120Ld manual IDE Controller, Keyboard and Mouse Controller, Network Controller

IDE Controller

The system includes a single channel enhanced IDE 32 bit interface controller for intelligent disk drives with disk controller electronics onboard. The controller has a connector located on the system board that supports a master and a slave device. The IDE controller provides support for the internally mounted CD-ROM.

The device controls:

!PIO and DMA transfer modes

!Mode 4 timings

!Transfer rates up to 33 MB/s

!Buffering for PCI/IDE burst transfers

!Master/slave IDE mode

!Up to two devices.

Keyboard and Mouse Controller

The keyboard and mouse controller is PS/2 compatible.

Network Controller

The system board includes a 10BASE-T/100BASE-TX network controller based on the Intel 82559 Fast Ethernet PCI Bus Controller. As a PCI bus master, the controller can burst data at up to 132 MB/sec. The controller contains two receive and transmit FIFO buffers that prevent data overruns or underruns while waiting for access to the PCI bus. The controller has the following:

!32-bit PCI bus master interface (direct drive of bus), compatible with PCI Bus Specification, Revision 2.1

!Chained memory structure with improved dynamic transmit chaining for enhanced performance

!Programmable transmit threshold for improved bus utilization

!Early receive interrupt for concurrent processing of receive data

!On-chip counters for network management

!Autodetect and autoswitching for 10 or 100 Mbps network speeds

!Support for both 10 Mbps and 100 Mbps networks, capable of full or half duplex, with back-to-back transmit at 100 Mbps.

!Support for Wake On LAN.

The network status LEDs on the system board indicate:

!Transmit/receive activity on the LAN

!Valid link to the LAN

!10/100 Mbps transfer mode.
