Features
The system board also contains three PCI bus I/O
expansion slots (Figure 2-3, C). The PCI architecture
supports 32-bit memory addressing and 32-bit data
transfers. One of these slots shares a common chassis
I/O expansion slot with one of the ISA slots; if you use
this slot as a PCI slot, you cannot use it as an ISA 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, T) provides
power backup for the real-time clock.
BIOS
A BIOS (Figure 2-3, B) 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.
Video
The system has a high-performance SVGA subsystem
that supports the following:
BIOS compatibility with VGA, EGA, CGA, Hercules
Graphics, and MDA.
1 MB of Video Random Access Memory (VRAM)
expandable to 2 MB (Figure 2-3, E).
16-bit bus for high-speed display memory access.
Hardware accelerated bit block transfers (BITBLT).
Display power management system.
Supports 72Hz refresh, non-interlaced at: 640x480,
800x600, 1024x768, or 1280x1024 resolutions.
