Chapter 5 – XVME-978 PCI Ethernet Controller Module
A high-performance 32-bit PCI bus mastering Ethernet controller may be added to the
XVME-655 via the XVME-978 Ethernet Controller. The XVME-978 features a NE2100
and NE1500 software-compatible Ethernet interface with support for both 10BaseT and
10Base2 connections. The XVME-978 is designed to mate with the two interboard
connectors. It also provides a second set of connectors to allow the installation of an
XVME-976 which offers PMC and PC/104 sites.
