- PART 3 - CD-ROM Drive Interface (Note: This only applies to OPTi 931's AD version)
-
- Interfacing a CD-ROM drive to your Sound Card:
-
- To interface/connect your new or existing CD-ROM drive to your
- sound card, please follow the simple steps below.
-
- If you are interfacing an existing CD-ROM drive to your sound card,
- you only need to follow steps 1 and 2 below since you should already
- have your existing CD-ROM driver setup in your CONFIG.SYS file.
- However, if your are interfacing a new CD-ROM drive, you will need
- to follow all 3 steps below; in which case, it is recommended that
- your perform step 1 first.
-
-
- 1. Hardware setup
-
- To connect your CD-ROM drive to your sound card, you will need
- to setup the correct data connector cable from your CD-ROM to
- your sound card. Please refer to your sound card installation
- manual for more details.
-
-
- 2. Modifying/Setting the INIT931.SYS setup program
-
- To interface your new or existing CD-ROM drive to your Sound Card,
- use an editor to open the CONFIG.SYS file for editing and locate
- the line "BASEDEV=INIT931.SYS..." This line should be at the first
- line of the file. Insert the following "CDTYPE:" option into the
- line and when completed, it should read:
-
- BASEDEV=INIT931.SYS CDTYPE:X CDBASE:XXX CDIRQ:X
-
- where <model> is the CD-ROM model denoted by the following characters:
- I - stands for IDE (secondary)
-
- For example, the following enables the interface for a SONY IDE CD-ROM.
-
- BASEDEV=INIT931.SYS CDTYPE:I CDBASE:376
-
- If the above INIT931.SYS line is not located, proceed to PART 1 of
- this document for details on installing the Sound Card setup program.
-
- Save the file and proceed to install the CD-ROM driver if needed.
-
-
- 3. Installing the CD-ROM driver
-
- Open the Selective Install program located in the System Setup
- folder and click on the icon next to the "CD-ROM Device Support"
- entry. A window with the list of OS/2 supported CD-ROM drivers
- will appear. Select (click on) the CD-ROM driver name belonging
- to your CD-ROM model and click on OK to confirm. Click on OK to
- start your CD-ROM driver installation.
-
- If you have already successfully connected your CD-ROM drive
- to your sound card as detailed in your installation manual, you
- may shut down OS/2 and reboot your system for the changes to
- take effect. If not, please proceed to connect your CD-ROM drive
- to your sound card after shutting down OS/2 and switching off
- your system.
-
-
-
- Only IDE CD-ROM drive models are supported by your Sound Card.
-
-
- PART 4 - Options for INIT931.SYS Sound Card Setup Program
-
- The options for INIT931.sys are different under Warp 3 and Merlin.
-
- The following lists the available options for the INIT931.SYS
- sound card setup program under Warp 3:
-
- MODE: wss, sb (default Windows Sound System)
- BASE: 220, 240 (for Sound Blaster mode, default 220)
- 534, E84, F44, 608 (for Windows Sound System mode, default 534)
-
- CDTYPE: None, IDE (default None)
- One character is adequate (e.g. CDTYPE:N CDTYPE:I)
-
- CDBASE: None, 376
- IDE - 376 (fixed)
-
- CDIRQ: None, 15
- IDE - 15 (fixed)
-
- SBIRQ: 5, 7, 10, 11 (default 7)
- SBDMA: 1, 2, 3 (default 1)
-
- WSSIRQ: 7, 9, 10, 11
- WSSDMA: 0, 1, 3 (default 1)
-
- NOTE: The WSS IRQ and DMA are specified here
- The audio PDD will query INIT931.SYS to
- learn of the device settings.
-
- GAMEPORT: 0,200,201,202,203,204,205,206,207 (0 disabled)
-
- Under Merlin 4.0. There's no options for INIT931.sys. INIT931.SYS
- directly queries Merlin PNP resource Manager to retreive all device
- resources.
-
- PART 5 - How to Reconfig the Hardware Settings
-
-
- Under Warp 3. Type "c:\sound931\minstall" and enter, then follow the
- directions from Part 1, step 8. Directory "SOUND931" was created in
- root directoy during the first installation process. It contains the
- same files as the installation disk.
-
- Under Merlin 4.0. PNP resources are used so there is no need to
- reconfig the hardware settings.
-
- PART 6 - WIN-OS/2 support
-
- Run MINSTALL and select OPTi WIN-OS/2 Audio Driver to install for
- WIN-OS/2 support.
- Before starting a WIN-OS/2 session, be sure to close all OS/2 Audio
- applications.
-
- PART 7 - Known Problems
-
- PART 8 - Brief Trouble-Shooting Session
-
- Problem: OS/2 cannot detect your sound card and/or CD-ROM
- Solution: Ensure that the BASEDEV=INIT931.SYS... line is located
- immediately before the LIBPATH= statement:
-
- Problem: No startup sound when starting OS/2
- Solution: Check if System Sound is enabled
-
- Problem: Sounds keep repeating
- Solution: This is due to an interrupt conflict on your system. To
- use a different interrupt selection, open the CONFIG.SYS
- file for editing and change the SBIRQ option in the
- INIT931.SYS line to a different interrupt.
-
- Problem: DOS games do not work under OS/2 DOS session
- Solution: Run OS/2 Add Programs located in the System Setup folder
- to ask OS/2 to add the set of DOS games on your system.
- This allows OS/2 to setup the DOS session settings best
- suited for your individual games such as DOOM.
-
- If the DOS game still does not run, this may be due to
- the incompatibility of the game with OS/2. Consult the
- OS/2 newsgroup - comp.os.os2.games on the internet for
- FAQs relating to this subject, or the FTP site -
- hobbes.nmsu.edu.
-
- Problem: IDE CD-ROM does not work
- Solution: Ensure that the IDE CD-ROM jumper is closed on your sound
- card. Consult your sound card manual for details.
-
- Problem: Compact Disc player does not generate sound.
- Solution: Go to Digital Audio. Under OPTIONS, select Monitor input.
-
- Problem: MINSTALL did not add the "BASEDEV=INIT931.SYS.." statement
- to config.sys.
- Solution: Reduce the length "LIBPATH=.." statement in config.sys to
- 255 characters or less.
