System Overview 1-9
IDE Controller
The system includes a single channel enhanced IDE 32 bit interface controller for
intelligent disk drives with disk controller electronics onboard. 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 Mode only.
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.
