8. General Installation Tips:
Hardware:
The Discovery CD 16 uses a Sound Blaster 16 sound card. The product was
used in its default configuration. The following are the factory defaults:
Feature:
Jumper position: Setting used:
Base I/O address
IOS0 closed 220( H)ex
Midi address
IOS1 closed 330( H)ex
Board Interrupt
IS0 open
IS1 closed IRQ5
8-bit DMA channel
DAS0 open
DAS1 closed
Channel 1
16-bit DMA channel DBS0 closed
DBS1 closed Channel 5
Joystick port JYEN closed
Enabled
Audio Output Amp OPSL pins 2 & 3 closed Audio amplified internally:
OPSR pins 2 & 3 closed no external amp needed
These settings can be found in the ‘GETTING STARTED’ manual that comes
with the product. The system uses a Matsushita model CR-563-B CD-ROM
drive.
From the factory the drive ID is set to 0. This jumper is on the rear of the
drive between the power connector and the data/ribbon cable.
PSB No: S-0171
Page: 4 of 5
The Discovery CD 16 Multimedia system comes with 5 3.5” diskettes. Three
diskettes are for the sound card, one is for a ‘Text-to-Speech’ application, and
one disk is for the CD-ROM device driver and utilities.
The Sound Blaster files are copied to the hard disk drive by an INSTALL.EXE
utility on disk 1. The utility will prompt the installer for the second and third
disks. The routine will modify the AUTOEXEC.BAT and CONFIG.SYS files.
Upon completion, the user is prompted to re-boot the system so that the
changes can take effect. The utility will also modify the Windows SYSTEM.INI
file. When you run Windows, a SB routine will modify and add the Sound
Blaster utilities to a new Program group. The routine will re-start Windows so
that the changes can take effect. The sound card can be tested in a DOS
environment by running TESTSB16. This file is located in the sound blaster
sub-directory SB16.
The utility will test the existence and functionality of the following areas:
I/O Address: IRQ: DMA channels:
220H 51,5
DSP Version:
4.05
The bold face values above are typical for the default configuration. The Sound
card passed all of the tests listed below:
2-operator FM Music
4-Operator FM Music
8-Bit Sound
16-Bit Sound
The CD-ROM files are copied to the hard disk drive by an INSTALL.EXE utility
on the disk 1. The routine will modify the AUTOEXEC.BAT and CONFIG.SYS
files.
Upon completion, the user is prompted to re-boot the system so that the
changes can take effect. To install CD-ROM into Windows, the user must
manually add the ‘QuickCD’ to the Sound Blaster 16 program group. Open the
‘Sound Blaster 16’ group, and from Program Manager File select New. Program
Item should have the bullet marked. Select the OK button. From the Program
Item Properties box select the Browse button. Scroll to the C:\SB16\PLAYCD
sub-directory. Select QCD.EXE as the file name and click the OK button. This
bring you back to the Program Item Properties box. For a Description enter
QCD. Click on the Change Icon button and choose a CD symbol for the icon
button. Click on the OK button and the QuickCD icon is present in the Sound
Blaster 16 program group. Insert an analog/music CD into player. If you click
on the CD icon without a disc installed you will get the following warning:
‘Ensure that you have a CD audio ready in your drive and CD MCI driver
installed in your system. The system is ready for use.

This Product Support Bulletin was specifically generated to address concerns
about compatibility of the Sound Blaster Kit in this system running under DOS
6.0. As documented the system is fully functional in that operating environment.
Concern was also expressed about using the DOS 6.0 memory manager
EMM386.EXE. Various packages that must run in expanded memory were
tested and experienced no errors.
Note: There is a known compatibility issue recording a digital file from any audio
input device at a sampling rate of 44Khz. The problem is apparent on
various PCs.
The issue is NOT problem on this system.
A large
digital file was created using SB 16 Mixer and SB Wave Studio from
Windows. The file was approximately 20Mb large after sampling a
dynamic ROCK source. Playback of the file rendered no dropouts of the
original material. The process is compatible on this system.

CPU
Q5. What microprocessors are being offered with the Epson Endeavor 486C
series computer?
A.
The Epson Endeavor 4SX/25C comes standard with an Intel™ i486SX™
microprocessor (CPU) running at 25MHz. The Epson Endeavor 4DX/33C
comes standard with an Intel™ i486DX™ CPU running at 33MHz. The
Epson Endeavor 4DX2/50C comes standard with an Intel™ DX2/50™ CPU
running at 50MHz. Common features of the different microprocessors
include backward compatibility with the 8088, 8086, 80286, and 80386
CPUs and a built-in 8KB cache. For system flexibility, the built-in CPU
cache can be disabled via SETUP.
The™ i486DX/33 and DX2/50 CPUs contains an on-chip numeric
coprocessor to increase the speed of floating point operations. This
coprocessor is backward compatible with the 387DX and 387SX math
coprocessors and complies to ANSI/IEEE standard 754-1985.
Q6. What processor upgrades are available in the Epson Endeavor 486C
computer?
A.
The Epson Endeavor 4SX/25C computer can be upgraded by installing an
Intel™ i487SX™ or Intel Overdrive CPU in the processor socket. Both of
these CPUs improve system performance by adding a numeric coprocessor
to speed up floating point calculations. The Intel Overdrive CPU doubles
the processor’s internal speed to further increase system performance.
The Epson Endeavor 4DX/33C computer can be upgraded by installing an
Intel Overdrive CPU in the processor socket. Like the Intel Overdrive CPU
for the 4SX/25, the Intel Overdrive CPU for the 4DX/33 also doubles the
processor’s internal speed to further increase system performance.

486C computer?
The Epson Endeavor 486C series computers utilize a Cirrus GD5422 VGA
graphics controller as its built-in video adapter. These computers include
512KB of video memory which may be upgraded to a full 1 MB of memory
by installing pluggable memory chips.
The Cirrus VGA graphics controller is 100% hardware and BIOS-
compatible with IBM® VGA display standards.
What type of RAM chips are used to upgrade the video memory to a
full 1MB on the Epson Endeavor 486C computer?
Increasing the Epson Endeavor 486C series computer’s video memory
requires four 256K x 4 bit, 70ns 20-pin DRAM ZIP (Zig-zag lnline
Package) chips. These chips install on the computer’s main logic board in
sockets VM00, VM01, VM02 and VM03.
