even though ISA cannot sustain 100 Mbps
traffic. Fast Ethernet could be adopted for ISA-
based nodes on the basis of the aggregate
traffic benefits.
FEAST is software-compatible with the existing
LAN9000 family of products and can use current
LAN9000 drivers in 16- and 32-bit Intel X86-
based environments.
Two different interfaces are supported on the
network side. The first is a conventional seven
wire ENDEC interface that connects to the
LAN83C694 for 10BASE-T and coax 10 Mbps
Ethernet networks. The second interface follows
the
MII
(Media
Independent
Interface)
specification draft standard, consisting of 4 bit
wide data transfers at the nibble rate. FEAST
also interfaces to the MII serial management
protocol. Four I/O ports (one input and three
output pins) are provided for LAN83C694
configuration.
