System Design

This section provides an overview of the system design.
System Board and Processor
The OPTi-designed Viper-N Chipset provides PCI bus, ISA bus, cache
controller, memory controller, and peripherals controller:
o OPTi 82C557M System Controller
o OPTi 82C556M Data Buffer Controller
o OPTi 82C558E Integrated Peripherals Controller
The computer supports a 75-MHz (P54C) CPU at 50-MHz bus speed, and a
100-MHz (P54LM) CPU at 66-MHz bus speed. Bus speed and processor core
voltage are configurable through resistor values at manufacturing. The
processor is soldered to the system board and is not removable.
System Memory Options
The main memory subsystem supports a standard 8 MB DRAM, expandable to a
maximum of 24 MB. The standard memory is soldered onto the system I/O
board. Expansion memory is available in 8 or 16 MB increments.
Diskette Drive
The computer uses a standard 3.5-inch, 1.44 MB diskette drive. The system
supports a single diskette drive in the computer.
Hard Drive
The computer supports an IDE hard drive. Cable select technology is
employed for device 0/device 1 selection. The hard drive mounts to the
system board with a hard drive bracket and connects directly to the system
board. A screw secures the hard drive bracket in place.
