I. Introduction
================
The CD-ROM packet comes with an installation utility. This installs
the nessary CD-ROM drivers needed by your CD-ROM drive to interface
with your PC.
Files
-----
The drive installation diskette includes the following files:
README.TXT -- User's guide
INSTALL.EXE -- CD-ROM installation program
ACERCD.SYS -- CD-ROM device driver
II. Requirements
=================
Hardware Requirements
---------------------
1. IBM PC/AT or compatible (80386-base system recommended)
2. Minimum EGA graphic display (VGA recommended)
3. Minimum 2M RAM recommended
4. one free IDE socket
5. one CD-ROM drive
Software Requirement
--------------------
1. Microsoft Windows 3.1 or later
2. MS-DOS version 5.0 or later
3. MS-DOS CD-Extension (MSCDEX 2.21) or later
III. Installation Procedures
============================
To install CD-ROM device driver, please follow the steps below:
1. Insert the installation diskette in your system's 3.5-inch floppy
disk drive.
2. Change the directory to that of your floppy disk drive, and type
the following at the DOS prompt:
INSTALL <Enter>
3. Follow the screen instructions to complete the installation.
4. Reboot system to activate the driver.
In general, you can just continually press the Enter key to install
the default settings. A directory (default C:\ACER) containing the
CD-ROM drivers is created during installation. Your AUTOEXEC.BAT
and CONFIG.SYS files are also modified to include the following lines:
CONFIG.SYS :
[common]
DEVICE=C:\ACERCD\ACERCD.SYS /D:ACERCD00
LASTDRIVE=N
AUTOEXEC.BAT :
C:\DOS\MSCDEX.EXE /D:ACERCD00
IV. Changing Settings after Installation
=========================================
To reconfigure the settings of the CD-ROM driver, use a text editor,
such as EDIT.COM, to modify the previous two command lines in CONFIG.SYS
and AUTOEXEC.BAT and then restart your computer to activate it.
Changing the CONFIG.SYS file
------------------------------
DEVICE=<path>\ACERCD.SYS /D:<device_name>
The <device_name> is the name MSCDEX will use to find the device
driver. The maximum length of <device_name> string is 8 characters.
Example:
DEVICE=C:\MYDRV\ACERCD.SYS /D:ACERCD01
Changing the AUTOEXEC.BAT file
----------------------------
MSCDEX /D:driver [/E] [/K] [/S] [/V] [/L:letter] [/M:number]
Example:
C:\DOS\MSCDEX /D:ACERCD01 /L:G /M:10
For more information, you can refer to the MS-DOS online help for MSCDEX
by typing HELP MSCDEX.
V. FastCD
==========
FastCD is the "Software Cache" function which use the EMS memory to
accelerate CD-ROM access speed .
Because it uses EMS memory , you must add the following two lines into
your CONFIG.SYS :
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE RAM
And , to enable this function , you must attach an option papameter -
"/E" or "/e" to ACERCD.SYS :
DEVICE=C:\ACERCD\ACERCD.SYS /D:ACERCD00 /E , or
DEVICE=C:\ACERCD\ACERCD.SYS /D:ACERCD00 /e
These will reserve 2048 KB to be the Cache Buffer ; if you want to
tune the reserved cache size , attach the parameter "/E:#####" to
ACERCD.SYS :
DEVICE=C:\ACERCD\ACERCD.SYS /D:ACERCD00 /E:1024 , or
DEVICE=C:\ACERCD\ACERCD.SYS /D:ACERCD00 /e:5192
The maximum cache size is 32 MBytes , and its unit is 16 KB ,
For example : if we want 17 KB , it will reserve 32 KB .
Notice : IF EMS memory is NOT enough , ACERCD.SYS will DISABLE
FastCD .

Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
