Introduction
Welcome to the ROCKY-3703EVR Celeron & Pentium® III
Single Board Computer. The ROCKY-3703EVR board is an
ISA/PCI form factor board, which comes equipped with high
performance Pentium® III Processor and advanced high
performance multi-mode I/O, designed for the system
manufacturers, integrators, or VARs that want to provide all the
performance, reliability, and quality at a reasonable price.
In addition, the ROCKY-3703EVR provides S3 Savage4 AGP4X
VGA on board. The VGA chip is 3D graphics chipset, which
provides up to 1920x1440x16-color resolution. The VGA on
board 2 to 32MB frame buffer using system memory.
This board has a built-in DiskOnChip™(DOC) Flash Disk Socket
for embedded applications. The DOC Flash Disk is 100%
software compatible with hard disks. Users can use any DOS
command without any extra software utility. The DOC currently
is available from 2MB to 144MB.
An advanced high performance super AT I/O chip – VIA
VT82C686B is used in the ROCKY-3703EVR board. Both on-
chip UARTs are compatible with the NS16C550. The parallel
port and IDE interface are compatible with IBM PC/AT
architecture.
The ROCKY-3703EVR uses dual Intel 82559 Fast Ethernet
Multifunction PCI Controller as a LAN controller. Which is a fully
integrated 10BASE-T/100BASE-TX LAN solution with high
performance networking functions and low power features.
The ROCKY-3703EVR uses the advanced VIA PM133/PL133
Chipset which is 100% ISA/PCI software compatible chipset with
PCI 2.1 standard.
