Introduction
Welcome to the ROCKY-558EV Pentium® w/ VGA &
10/100MBps Ethernet Single Board Computer. The ROCKY-
558EV board is an PICMG bus form factor board, which
equipped with high performance Pentium® CPU and advanced
high performance VGA and Ethernet, designed for the system
manufacturers, integrators, or VARs that want to provide all the
performance, reliability, and quality at a reasonable price.
This board built-in DiskOnChip™(DOC) Flash Disk for embedded
application. The DOC Flash Disk is 100% compatible to hard
disk. User can use any DOS command without any extra
software utility. The DOC currently is available from 2MB to
72MB.
An advanced high performance VGA chip –Winbond W9970CF
is used in the ROCKY-558EV board. The W9970CF integrated
Video Graphics Accelerator in a single chip.
In addition, the ROCKY-558EV provides two 168-pin DIMM
sockets for its on-board DRAM. DIMM module is 3.3V
SDRAM.and max. 128MB for one module.
The board’s RTL8139 network chipset provides 10MBps or
100MBps Ethernet with auto-sensing function.
ROCKY-558EV uses the advanced ALI Chipset Aladdin 4+
which is 100% ISA/PCI compatible chipset with PCI 2.1 standard.

Installation
This chapter describes how to install the ROCKY-558EV. At first,
the layout of ROCKY-558EV is shown, and the unpacking
information that you should be careful is described. The
jumpers and switches setting for the ROCKY-558EV's
configuration, such as CPU type selection, system clock setting,
and watch dog timer, are also included.

•CPU Core Voltage Selection :
Please check the CPU Core Voltage before you install the
CPU. Right now new Intel MMX CPU is dual voltages for
core and I/O,the I/O is 3.3V but the core is 2.8V. This kind
of CPU design will enhance the low power consumption
capability. As for the general Pentium® CPU is one voltage for
I/O and Core - 3.3V,3.4V,or 3.5V

2.3 Watch-Dog Timer
The Watch-Dog Timer is enabled by reading port 443H. It should
be triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a reset
signal to start again, or activate NMI to CPU. The Watch-Dog
Timer is disable by reading port 043H.
