System Overview 1-9
Real-Time Clock/Calendar
The real-time clock provides system clock/calendar information stored
in a non-volatile memory (NVRAM). The real-time clock battery provides
power backup for the real-time clock.
BIOS
A BIOS and Setup Utility are located in the Flash EPROM on the system
board and include support for system setup and PCI/ISA Plug-and-Play
auto-configuration. A number of security, reliability, and management
features also have been incorporated to meet vital server needs.
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:
32-bit PCI bus master interface (direct drive of bus), compatible with
PCI Bus Specification, Revision 2.1
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 Mbps network speeds
Support for both 10 Mbps and 100 Mbps networks, capable of full or
half duplex, with back-to-back transmit at 100 Mbps.
