Controllers
The following provides a description of the controllers.
IDE Controller
The system includes a single channel enhanced IDE 32 bit interface. 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 100 MB/s
!
Buffering for PCI/IDE burst transfers.
Keyboard and Mouse Controller
The keyboard and mouse controller are PS/2 compatible.
Network Controller
The baseboard includes two network interface controllers (NICs):
!
Intel 82550 NIC that supports 10Base-T and 100Base-TX networks
!
Intel 82544 NIC that supports 10Base-T, 100Base-TX networks, and 1000BASE-T
networks.
The 82550 controller supports the following features:
!
32-bit PCI, CardBus master interface
!
Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY
!
IEEE 820.3u auto-negotiation support
!
Chained memory structure similar to the 82559, 82558, 82557 and 82596
!
Full duplex support at both 10 Mbps and 100 Mbps operation
!
Low power +3.3 V device
!
IP checksum off-loading.
NIC 1 can be used as both a network interface and server management interface.
The 82544 controller supports the following features:
!
Direct 32/64-bit, 33/66-MHz interface to the PCI bus
!
Integrated IEEE 802.3 1000BASE-T, 100BASE-TX, and 10BASE-T
!
Integrated third-generation MAC and proven IEEE 803.3ab compatible PHY
!
Full duplex support for 10-Mbps, 100-Mbps, and 1000 Mpbs operation
