Intel SE7500CW2 Video Controller, Network Interface Controller NIC, 32-bit/33MHz PCI Subsystem

32-bit/33 MHz PCI Subsystem

The 32-bit/33 MHz PCI segment includes the following embedded devices and connectors:

•Two 5 V keyed PCI expansion slots

•Integrated Intel EtherExpress PRO100+ 10/100 megabit PCI Ethernet controller (Intel 82550PM)

•Integrated ATI Rage XL video controller with 8 MB of on-board SDRAM

•Integrated Promise PDC20267 ATA-100 RAID controller

32-bit/33 MHz PCI features include:

•Bus speed up to 33 MHz

•5 V signaling environment

•Burst transfers up to a peak of 132 MB/s

•8-, 16-, or 32-bit data transfers

•Plug and Play ready

•Parity enabled

Video Controller

The Server Board SE7500CW2 includes an ATI Rage XL video controller, 8 MB video SDRAM, and support circuitry for an embedded SVGA video subsystem.

The SVGA subsystem supports a variety of modes: up to 1600 x 1200 resolution for CRT displays and up to 1024 x 768 resolution for TFT displays, and up to 16.7 million colors. The Server Board SE7500CW2 provides a standard 15-pin VGA connector.

Network Interface Controller (NIC)

The Server Board SE7500CW2 includes two 10Base-T/100Base-TX network controllers based on the Intel 82550PM Fast Ethernet PCI Bus Controller. As a PCI bus master, the 82550PM controller can burst data at up to 132 MB/s. Status LEDs are included on the external NIC connector.

You can disable the embedded NIC in BIOS Setup Utility. When disabled it is not visible to the operating system.

Supported Network Features

The Server Board SE7500CW2 supports the following features of the 82550PM controller:

•Glueless 32-bit PCI Bus Master Interface (Direct Drive of Bus), compatible with PCI Bus Specification, revision 2.1 / 2.2

•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 MB/s network speeds

•Support for both 10 MB/s and 100 MB/s networks, full or half duplex-capable, with back-to-back transmit at 100 MB/s

•Integrated physical interface to TX magnetics

•The magnetics component terminates the 100Base-TX connector interface. A flash device stores the network ID

•Support for Wake on LAN (WOL)
