1. Introduction
SAGP-845EV is a PSB form factor board to work with a high
performance processor. It is equipped with advanced multi-
mode I/O, and designed for system manufacturers,
integrators, or VARs who want to provide all the
performance, reliability, and quality at a reasonable price.
In addition, SAGP-845EV’s onboard Intel 845G MGCH chip
features built-in AGP4X capability which provides 3D
graphics up to 2048x1536x16-bit-color resolution. The
onboard VGA shares 8MB system DDR-SDRAM.
An advanced high performance super AT I/O chip – ITE
IT8712 is used in the SAGP-845EV board. Both on-chip
UARTs are compatible with the NS16C550. The parallel port
and IDE interface are compatible with IBM PC/AT
architecture.
SAGP-845EV’s built-in ICH4 has 10/100 Fast Ethernet LAN
capability. It’s fully integrated 10BASE-T/100BASE-TX LAN
solution with high performance networking functions and low
power features.
SAGP-845EV uses the advanced Intel 845G Chipsets that is
a 100% software-compatible chipset with PCI 2.2 standard.
This PIAGP CPU card must be installed on IEI
PCIAGP/PXAGP series backplanes. If onboard ISA interface
is required, please be sure to install PISA-KIT01 daughter
board on the specific socket on the backplane before ISA
cards are installed to make sure the system works properly.

2. Installation
This chapter describes how to install the SAGP-845EV. At first, the layout
of SAGP-845EV is shown, and the unpacking information that you should
be careful with is described. The jumpers and switch settings for the
SAGP-845EV 's configuration, such as CPU type selection, system clock
setting, and watchdog timer, are also included.

2.2 Clear CMOS Setup
If the user wants to clear the CMOS Setup data (for example, the
user forgot the password and needed to clear the setup data then set
the password again), the user should close the JP2 (set the jumper
to 2-3) about 3 seconds, then open it again. For normal operation,
set the jumper to 1-2 or open JP2.
