Epson ActionTower 7500 User manual

EPSON
®
User’s Guide Update
In order to take advantage of the latest technology, the system board
in your computer has been completely redesigned.
This update includes last-minute information that was not available
at the time your on-screen User’s Guide was created.
Extenal Cache
Your computer supports up to 1MB of external cache. If your system
already has cache installed, it can be increased up to 1MB. However,
you cannot install cache chips yourself. Please contact your
Authorized EPSON Servicer if you want to install cache memory in
your computer.
Power Management
The Windows
®
95 CD-ROM Autoplay feature operates continuously
and prevents power management from being fully effective on your
system. If you want to take advantage of your computer’s power-
saving features, you must use the Widows Device Manager to
disable Autoplay. See your Windows documentation for instructions.
System Board
Because your computer’s system board has been redesigned, the
illustrations showing the board in Chapter 4 of your User’s Guide are
incorrect. Board components such as jumpers and SIMM sockets have
been relocated. However, disk drives and other internal components
are shown correctly in the illustrations.

The illustration below shows the correct location of jumpers and
other components on the system board in your computer.

The jumpers on the system board have been renumbered, as shown
in the tables below. The factory default settings are indicated by an
asterisk (*).

Introduction
Your new EPSON® computer is a full powered, full featured
system that gives you complete access for all your business or
home computer needs. And because your computer is plug and
play compliant and designed to take advantage of Microsoft®
Windows®95, you’ll be able to use all the latest technology.
With the computer’s high-performance processor and memory
you can run a vast array of the latest programs, utilities, and
games designed for productivity and fun.
Your system’s state-of-the art PCI (Peripheral Component
Interconnect) bus architecture gives you fast and efficient
access to both PCI and IDE option cards. It also provides PCI
performance for IDE drives and your VGA or high-resolution
monitor.
And when you’re ready for even more capability, you can
expand your system, video, and cache memory, install option
cards or additional drives, and upgrade your processor.
Computer Features
Your computer offers the following features:
Upgradable 486-class processor
4 or 8MB of RAM (Random Access Memory), expandable
to 128MB
PCI-based main system board providing PCI caching,
memory, bus control, video control, and IDE (Integrated
Drive Electronics) device control
Introduction 1

High-speed, PCI video controller with 64-bit DRAM video
interface and 32-bit CPU interface
Two PCI ATA-2 compatible, enhanced IDE interfaces
supporting up to four IDE devices, such as hard disk drives
and CD-ROM drives (two on each interface)
8 or 16KB of internal cache in the processor and up to
512KB of external cache on the main system board
1MB of on board video memory for resolutions up to
1024 x 768; memory expandable to 2MB
Three Energy Star compliant power-saving modes for the
CPU, video, and hard disk drives in standard
configurations
Three 16-bit, ISA (Industry Standard Architecture) option
slots and two PCI option slots supporting up to two PCI
bus m aster cards
On the slim line model, space for up to four mass storage
devices, three externally accessible and one internal; on the
tower model, space for up to seven mass storage devices,
four externally accessible and three internal.
Power-saving Features
In standard configurations, this computer complies with the
United States Environmental Protection Agency’s Energy Star
Program, which promotes the manufacture of energy-efficient
printers, computers, and monitors. Your computer’s “Green
PC” features place the CPU, video, and hard disk drives in
power-saving modes when the mouse and keyboard have been
inactive for a specified period of time. You can customize the
Green PC features in the SETUP program.
2 Introduction

ISA and PCI Expansion Buses
Your computer includes expansion buses for two types of
option cards: ISA and PCI. The PCI bus provides extremely fast
data transfer (33 MHz) for up to two high-performance PCI
cards, such as high-speed video cards. PCI cards use plug and
play technology that automatically configures resources used
by the card, such as interrupt requests and memory addresses.
The ISA bus transfers data at 8.33 MHz for up to three 16-bit
ISA option cards. You can use these slots for standard ISA
cards such as fax/ modem cards, sound cards, and SCSI (Small
Computer System Interface) cards.
System and video BIOS
The computer’s system and video BIOS are contained in a flash
memory device on the main system board, which you can
upgrade without replacing the chip.
Your computer supports shadowing of the system and video
BIOS to allow BIOS routines to run from fast, 32-bit RAM
instead of from the slower, S-bit flash device.
