Features
The system board also contains five PCI bus master I/O
expansion slots (Figure 2-3, B). One of these slots
shares a common chassis I/O expansion slot with one of
the EISA slots; if you use this slot as a PCI slot, you
cannot use it as an EISA slot.
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, S) 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.
