     IDE/ATAPI CD-ROM DEVICE DRIVER VER 2.22


The installation program can install the CD-ROM under DOS and WINDOWS 3.1
system. If your system is WINDOWS 95 or others, the installation is not
necessary.

The setup program automatically modifies the CONFIG.SYS and AUTOEXEC.BAT file
so that your computer can access the CD-ROM drive. However, there are some
parameters that can be changed if you wish.This section explains the function
of each parameter. Use a text editor, such as MS-DOS 'EDLIN' or 'EDIT', to
modify the appropriate line in your CONFIG.SYS and AUTOEXEC.BAT file.


DEVICE DRIVER (ATAPICD.SYS) PARAMETER LIST :

 DEVICE=ATAPICD.SYS [ /D:<device_names>]
 LASTDRIVE=Z

where the arguments are:

  /D:<device_names>
The character device names that will be used by MSCDEX.EXE to find and
communicate with the device driver (default is "ATAPI_CD").


MICROSOFT CD-ROM EXTENSIONS PARAMETERS LIST :

 [drive:][path] MSCDEX.EXE /D:device name[/M:n][/E]

[drive:] [path] MSCDEX.EXE
Specifies the location (drive and directory) of the MSCDEX.EXE file.
The default setting is the ATAPI directory of the boot drive.

  /D: device name
Specifies the name of the CD-ROM drive (8 characters maximum).
This must be identical to the device name specified in the device driver in the
CONFIG.SYS file.  For example :
C:\ATAPI\MSCDEX.EXE /D:ATAPI_CD

  [/M:n]
Specifies the number of sector buffers for temporary storage of the most recent
disc data.  For example to specify four sector buffers you would use:
C:\ATAPI\MSCDEX.EXE  /D:ATAPI_CD  /M:10

The installation program will set this value to 10.

Note :The greater this value, the better the CD-ROM drive will perform.  However, each buffer uses about 2k of memory and specifying too many buffers may slow down computer operation or interface with other programs which have large memory usage requirements.  Using expanded memory (see the /E option in this section) or loading MSCDEX.EXE into high memory (refer to your MS-DOS User's Manual or Memory Manager User's Manual) may allow you to specify a larger number of buffers to enhance CD-ROM performance and

  [/E]
Instructs the computer to use expanded memory, if available.  For example :
C:\ATAPI\MSCDEX.EXE /D:ATAPI_CD /E

Note:That you must first load an expanded memory driver before using this option.  If no expanded memory driver is loaded, the following error message appears:
Expanded memory not present or not usable
