Features
Bus Master I/O Expansion Slots
The server's expansion capabilities meet the needs of
file and application servers for high performance I/O by
providing a combination of PCI local bus and EISA
connectors. The system board offers six dedicated PCI
slots and four dedicated EISA slots.
The system board contains four EISA bus master I/O
(input/output) expansion slots (Figure 2-3, B). The
EISA architecture supports 32-bit memory addressing
and 16-bit or 32-bit data transfers for the CPU, DMA,
and bus masters.
The system board also contains six PCI bus master I/O
expansion slots (Figure 2-3, D).
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 (Figure 2-3, G) 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.
