IDE Controller
The system includes a dual channel enhanced IDE
interface controller. The controller has a primary and
secondary connector located on the system board, each
connector supporting a master and a slave device. The IDE
controller provides support for the internally mounted CD-
ROM and an optional tape device.
Network Controller
The system board includes a 10BASE-T/100BASE-TX
network controller based on the Intel 82558 Fast Ethernet
PCI Bus Controller. As a PCI bus master, the controller
can burst data at up to 132 MB/sec. The controller
contains two receive and transmit FIFO buffers that
prevent data overruns or underruns while waiting for
access to the PCI bus. The controller has the following:
T
32-bit PCI bus master interface (direct drive of bus),
compatible with PCI Bus Specification, Revision 2.1
T
Chained memory structure with improved dynamic
transmit chaining for enhanced performance
