Welcome to the wonderful world of Sony MS-DOS CD-ROM Extensions. Prior to installation, make a backup copy of this Library disk using DISKCOPY command. Store the master disk in a safe place and use the copy for installation. Even if the supplied Library disk is write-protected, you should not protect the backup copy of the Library disk. Otherwise you can not install Sony MS-DOS CD-ROM Extensions. This installation utility consists of batch files, screen images and execution programs. The structure of this Library disk and the stream of the batch files are described in CHAPTER 6 of this document. Type "INSTALL" and press Enter key. You can install Sony MS-DOS CD-ROM Extensions on a target disk by following on-screen instructions. The installation manual describes about basic installation, however you can install Sony MS-DOS CD-ROM Extensions using another method. Refer to "ADVANCED INSTALLATION" of this document.  page 3 CHAPTER 2. PREPARATION. 2.1. PREPARATION of THE TARGET FLOPPY DISK. If you wish to install the MS-DOS CD-ROM Extensions on your floppy disk, it is necessary to prepare a bootable floppy disk. The disk should be formatted as instructed below, and DOS is transferred to the disk. We call the disk "Target floppy disk" in the document. C:\>FORMAT A: /S and 2.2. CONFIRMATION OF YOUR COMPUTER. Before installation, confirm the followings. Type of your computer. IBM PC/AT or PC/XT? The number of floppy disk drives installed on your computer. With hard disk drive or not. The drive letter which the MS-DOS was booted from (A or C).  page 4 2.3. INSERTION OF THE LIBRARY DISK AND THE TARGET DISK After booting, you have to insert the Library disk and the target disk as follows. CASE.1: If your computer has one floppy disk drive and no hard disk drive, insert the Library disk into drive A. CASE.2: If your computer has two floppy disk drives and no hard disk drive, insert the Library disk into drive B. (The boot disk has been inserted in drive A.) CASE.3: If your computer has a hard disk drive and one floppy disk drive, insert the Library disk into drive A. CASE.4: If your computer has a hard disk drive and two floppy disk drives, insert the Library disk into drive B and insert the target floppy disk into drive A. (If you install the MS-DOS CD-ROM Extensions on the hard disk drive, you do not have to insert the target floppy disk into drive A, and you can insert the Library disk into drive A or B.)  page 5 CHAPTER 3. BASIC INSTALLATION. Change the logged drive from the boot drive to the drive with Library disk. Then type INSTALL and the Enter key at the DOS prompt. The installation utility will start and press any key until the following messages appear on the screen. Continue responding to the message. Type one of the followings and press the Enter key at the DOS prompt. The '??' is your computer type, PC/AT or PC/XT. Type like 'CH1 AT Sub_Dir'. CH1 ?? {Sub_Dir} ; Install on a hard disk. AF2 ?? {Sub_Dir} ; Install on a floppy disk using double floppy disk drive system. AF1 ?? {Sub_Dir} ; Install on a floppy disk using single floppy disk drive system.  page 6 CHAPTER 4. ADVANCED INSTALLATION. Type "ADINST" and press Enter key, then the following messages appear. ******************* ADVANCED INSTALLATION. ************************** Type one of the followings and press Enter key. If you omit the SUB_DIR, Sony MS-DOS CD-ROM Extensions will be installed on the root directory. CH1 AT(or XT) {Sub_Dir} ;Booted from the hard disk C. Install on SUB_DIR of the hard disk. CF1 AT(or XT) {Sub_Dir} ;Booted from the hard disk C. Install on SUB_DIR of floppy disk using single floppy drive system. CF2 AT(or XT) {Sub_Dir} ;Booted from the hard disk C. Install on the SUB_DIR of floppy disk using double floppy drive system. AF1 AT(or XT) {Sub_Dir} ;Booted from floppy disk A. Install on the SUB_DIR of a floppy disk using single floppy disk drive system. AF2 AT(or XT) {Sub_Dir} ;Booted from floppy disk A. Install on the SUB_DIR of a floppy disk using double floppy disk drive system.  page 7 4-1. ON A SUB DIRECTORY. If you wish to specify the sub-directory, type like "A:\>CH1 AT SUB_DIR" and Enter key. Then, the batch files and SHELL.COM do the followings; 1. Make a sub-directory of SUB_DIR on the target disk. 2. Make backup files of AUTOEXEC.BAT and CONFIG.SYS with extension name of "BAK" on the sub-directory, if the target disk is the hard disk C. 3. Append or make the executable path name of the "DRIVE_LETTER:\SUB_DIR;" in AUTOEXEC.BAT file. 4. Append the sub-directory, on which the device driver exists, in CONFIG.SYS file. *** An example of AUTOEXEC.BAT file after the installation. *** path=C:\Sub_Dir;%path% MSCDEX /D:MSCD220 /M:4 /L:S /V *** An example of CONFIG.SYS file after the installation. *** DEVICE = C:\Sub_Dir\SONY_CDU.SYS /D:MSCD220 /U:1 /B:340 /M:H /Q:* /T:* LASTDRIVE=Z  page 8 4.2. ON A FLOPPY DISK BOOTED FROM THE HARD DISK C. Someone may wish to install the MS-DOS CD-ROM Extensions on a floppy disk when DOS was booted from the hard disk C. An advantage of this is that you can install the MS-DOS CD-ROM Extensions without changing the hard disk environment, and that you can use the floppy disk when you need to run the MS-DOS CD-ROM Extensions. Follow the sequence below for installation. 1. Boot your computer from the hard disk drive C. 2. If your computer has two floppy disk drives, insert the Library disk into drive B, and the target disk into drive A. If your computer has one floppy disk drive, insert the Library disk into drive A. 3. Change the logged drive to the drive with Library disk. 4. Type below and Enter key, then the installation utility will start. B:\>CF2 AT(or XT) {Sub_Dir} ; Double floppy disk drive system. A:\>CF1 AT(or XT) {Sub_Dir} ; Single floppy disk drive system. NOTE: In case of only one floppy disk drive system, you have to repeat to insert the library disk and the target disk by following on-screen messages.  page 9 CHAPTER 5. CUSTOMIZATION. Sony MS-DOS CD-ROM Extensions has some parameters in AUTOEXEC.BAT and CONFIG.SYS files. After installation the MS-DOS CD-ROM Extensions, you may customize them by using your favorite editor. Check the parameters first by using TYPE command as follow. Each parameter is set after "/", such as /L:S. A:\>TYPE AUTOEXEC.BAT ; You can find the string below on the screen. MSCDEX /D:MSCD220 /M:4 /L:S /V A:\>TYPE CONFIG.SYS ; You can find the two strings below on the screen. DEVICE=SONY_CDU.SYS /D:MSCD220 /U:1 /B:340 /M:H /Q:* /T:* LASTDRIVE=Z  page 10 5.1. CHANGING THE PARAMETERS IN AUTOEXEC.BAT FILE. To start the MS-DOS CD-ROM Extensions when you boot the computer, you must include the following string in AUTOEXEC.BAT file. You can omit parameters in two square braces. MSCDEX /D:device_name [/M:number /L:drive_letter /V] Change each parameter according to the followings if necessary. NOTE: Reboot by pressing Ctrl-Alt-Del keys after you changed the parameters. /D:device_name You can change the device_name using a maximum of eight letters, such as /D:CDROM001. You must write the same device_name in the CONFIG.SYS file too, otherwise the MS-DOS CD-ROM Extensions never works. The default setting is MSCD220.  page 11 /M:number This parameter specifies the number of sector buffers to be used for caching the path table of a CD-ROM disc. Each drive must have a minimum of 4 buffers, but the larger number is, the better the performance will be. If you delete this parameter, the default value of 4 is set. /L:drive_letter You can write C to Z that is not in use by other peripherals, however make sure which drive letters are already used by other peripherals. You should not set the drive letter used by other peripherals as the drive_letter. If you omit this parameter, the letter which comes after the one assigned to the current last drive. The default setting is S. /V If this parameter is written, you can see the information about memory usage when you boot the computer. You don't have to set the parameter if not necessary.  page 12 5.2. CHANGING THE PARAMETERS IN CONFIG.SYS FILE. To start the MS-DOS CD-ROM Extensions, you must include the following strings in CONFIG.SYS file. You can omit parameters and a string in two square braces. DEVICE=SONY_CDU.SYS /D:device_name [/U:un /B:xxx /M:mode /Q:irq /T:drq] [LASTDRIVE=last_letter] Change each parameter according to the following explanations. NOTE: This device driver ignores IRQ channel. Reboot by pressing Ctrl-Alt-Del keys after you changed the parameters.  page 13 LASTDRIVE=last_letter This string sets the maximum number of drives that you may access. The last letter represents the last valid drive letter that MS-DOS may accept. Set the last_letter regarding the drive_letter specified by "/L:drive_letter" in AUTOEXEC.BAT file and the unit number specified by "/U:un" in CONFIG.SYS file as following example. The default setting is W. the drive_letter the un the last_letter ------------------------------------------------------- S 1 T S 2 U S 3 V S 4 W E 1 F ------------------------------------------------------- If your computer is on a network, set the last_letter which is larger than the total number of peripherals in your system, so that new net work peripherals can be added after booting. Notice though this string is allowed to be omitted, it is better to set the last_letter to avoid allocation error of the drive letter for CD-ROM drives.  page 14 /D:device_name See the CHAPTER 5.1. /U:un The 'un' specifies the unit number of CD-ROM drives connected in a daisy chain. You can write 1 to 4 as the un, according to the number of CD-ROM drive(s) connected in a chain. If you omit this parameter, the default value of 1 is set. /B:xxx The 'xxx' specifies the base address of the CD-ROM host adapter with a hexadecimal number. Make sure that this number and the switch settings on the host adapter are same. Also make sure that the address is not used by other peripherals. If you omit this, the default value of 340h is set. /M:mode The 'mode' specifies the data transfer mode. D for DMA transfer P for software transfer and H for high speed software transfer (for fast CPU.) Notice if you specify "D", you have to specify the number of DRQ channel by /T:drq parameter. Refer to the next page. If you omit this, the default value of H(PC/AT) or P(PC/XT) is set.  page 15 /Q:irq The driver does not use the IRQ, even if specified by this switch. /T:drq The 'drq' specifies the DRQ channel number for DMA transfer. When you select the DMA transfer using /M:D above, you must select a DRQ channel number. You can select 1, 2 or 3 as the 'drq'. Make sure that this number and the switch settings on the host adapter are same. Also make sure that the channel is not used by other peripherals. If you do not use the DMA transfer, omit this or write '/T:*'.  page 16 CHAPTER 6. STRUCTURE OF THE LIBRARY DISK. 6-1. DIRECTORIES AND FILES.
