System specifications 87
The high-bandwidth PCI local bus eliminates data bottlenecks found
in traditional systems, maintains maximum performance at high clock
speeds, and provides a clear upgrade path to future technologies.
Expansion board slots
The system board has three ISA expansion board connectors and four
32-bit PCI connectors. One ISA and one PCI connector use the
shared PCI/ISA slot on the back of the system unit. The Intel
PCI/ISA IDE Accelerator chip provides the logic for enabling the
ISA bus functions.
With 24-bit memory addressing, a 16-bit data path, and an 8-MHz
clock, the ISA bus supports all peripherals compatible with the IBM
®
AT™ standard.
For PCI functions, the Accelerator chip provides 32-bit memory
addressing, 32-bit data path, and up to a 33-MHz clock speed.
BIOS
The Phoenix Basic Input/Output System (BIOS) is stored in an Intel
PA28FB200BX 2-MB Flash EPROM on the system board. The Flash
EPROM also contains the Setup program, Power On Self Test
(POST), advanced power management, PCI auto-configuration
utility, and a plug and play BIOS program.
The BIOS programs execute POST, initialize processor controllers,
and interact with the display, diskette drive, hard disk, communication
devices, and peripherals.
With Flash EPROM, a ROM BIOS change:
is fast and easily done using a Flash utility
eliminates the expensive replacement of ROM BIOS chips,
and reduces system maintenance costs
