During system initialization at startup, the E100 (PCI BIOS system
ROM) configuration software automatically selects an unused inter-
rupt line and I/O addresses for use with the card. You do not need to
set interrupts, I/O addresses, jumpers, or switches to configure the
card.
Open Transport is Apple’s standards-based networking and communi-
cations software, including the AppleTalk and TCP/IP control panels
and other software components. It provides a foundation for flexible,
high performance network communications including connectivity to
LocalTalk, ethernet, AppleTalk and TCP/IP networks, and services
including printing, file sharing, and electronic mail. Open Transport
was specially designed to take advantage of the PowerPC processor in
your SuperMac system and is an integral and required feature. Open
Transport has been pre-installed onto your SuperMac System.
Configuring 10Mbps, 100Mbps, or Full Duplex Operation
The E100 card provides an auto-negotiation feature that allows the
connected devices to automatically configure to the highest perfor-
mance mode of operation. The hierarchy of this mode of operation is
■
100BASE-TX Full Duplex
■
100BASE-TX
■
10BASE-T Full Duplex
■
10BASE-T
This means that during startup the E100 card automatically connects
at the appropriate speed (10Mbps or 100Mbps) and/or Full Duplex
without user intervention. The Full Duplex operation can only be con-
figured with a hub or a switch that supports it.
If you are initially planning to use the E100 card to run at 10Mbps
speed, when you are ready to upgrade to 100Mbps (100BASE-TX), you
will not need to modify the configuration or settings. The same driver
will run in both 10Mbps or 100 Mbps speed.
Auto-negotiation preserves network integrity because a connection
cannot occur without a common mode of operation between connecting
devices.
