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.
