README file for CD-ROM device driver for IDE V1.0 =================================================================== I. Introduction II. Requirements III. Installation Procedures IV. Changing Settings after Installation V. FastCD 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 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=\ACERCD.SYS /D: The is the name MSCDEX will use to find the device driver. The maximum length of 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 . ================================= END =============================
