Intelligraphics Sanyo CDR-H94A OS/2 Driver 03/02/95 Release 1.02 ---------------------------------------------------------------------------- This diskette contains the BETA release version of the Sanyo CDR-H94A driver for OS/2 2.11, OS/2 for Windows, and OS/2 Warp v3. The included driver is a beta release, and includes some known limitations. Please see the errata at the end of this readme file. ---------------------------------------------------------------------------- INSTRUCTIONS FOR SANYO CDR-H94A DEVICE SUPPORT INSTALLATION These instructions describe the procedure required to add support for your Sanyo CDR-H94A CD-ROM drive to a machine which already has OS/2 installed on it. For instructions regarding the installation of OS/2 itself from the drive, see the section titled "INSTRUCTIONS FOR OS/2 INSTALLATION." NOTE: If you already have OS/2 CD-ROM support installed on your machine for another model of drive, you may proceed directly to Step 5. 1. Open OS/2 SYSTEM. 2. Open SYSTEM SETUP. 3. Open SELECTIVE INSTALL. 4. Select CD-ROM Device Support, and choose "Other" for the model of CD-ROM device. Follow the prompts of the Selective Install program and use the Help feature if necessary. 5. From the SYSTEM SETUP folder, open DEVICE DRIVER INSTALL. 6. Fill in the drive letters and path information for your OS/2 system and the location of this device driver install package. Note that this package may be run from a diskette or from a subdirectory on your hard disk. Click on the Install button. 7. Double click on the selection which ends in "Default Configuration." Follow the prompts of the Device Driver Install program, and use the Help feature if necessary. 8. Sanyo CDR-H94A OS/2 Device Support Installation is complete. Shutdown your system using the desktop ShutDown utility, reboot your system, and your CD-ROM drive will be present and functional. ---------------------------------------------------------------------------- INSTRUCTIONS FOR OS/2 INSTALLATION These instructions describe the procedure required to install the OS/2 operating system from the CD version on your Sanyo CDR-H94A. For instructions regarding the installation Sanyo CDR-H94A device support on a machine which already has OS/2 installed on it, see the section titled "INSTRUCTIONS FOR SANYO CDR-H94A DEVICE SUPPORT INSTALLATION." The CD version of OS/2 comes with two floppy diskettes which are used to boot the target machine. After booting, the install proceeds from the CD-ROM drive to the hard disk. The second diskette, titled Diskette #1, contains a config.sys file which attempts to install all OS/2 CD-ROM device drivers. At this time, your Sanyo driver is not included on the diskettes which IBM ships. You must make a backup copy of diskette 1 and modify it before you can install OS/2 from your Sanyo CDR-H94A. The procedure to do this is as follows: 1. Boot from either your existing DOS operating system, or from the OS/2 diskettes (selecting the command prompt option when prompted). 2. Make a copy of diskette #1 by entering the following command: DISKCOPY A: A: 3. Copy the file named SANYO001.ADD from this diskette to your newly created Diskette #1: COPY A:SANYO001.ADD A: 4. Edit the config.sys file contained on the new diskette #1. If you are unsure of how to do this, see the editor instructions in the section of this file titled "ADVANCED CONFIGURATION." 5. Add the following line to the config.sys file after all the other BASEDEV=XXXXXXXX.ADD statements: BASEDEV=SANYO001.ADD 6. Reboot from the OS/2 Installation diskette and the installation of OS/2 from your Sanyo-CDR-H94A will proceed as per normal. A more detailed description of this procedure can be found in the hardcopy version of your OS/2 Installation Guide. ---------------------------------------------------------------------------- ADVANCED CONFIGURATION Advanced Configuration is accomplished by editing your config.sys file to pass command line parameters to the Sanyo CDR-H94A device driver. Most of these parameters are entirely optional, although some users may be required to make an advanced configuration. The filename of the driver is SANYO001.ADD, and the line in config.sys which loads this driver reads, "BASEDEV=SANYO001.ADD." Parameters are added to the end of this line, and any number of them may be present. The following parameters are recognized by the driver: /V -This option causes the driver to use verbose mode, where a detailed message is output to the display during system boot. This option is turned on by default during the installation of the driver. /Q -This option causes the driver to use quiet mode, where no indication is given when the driver cannot find a CD-ROM drive. This option is valuable in mobile situations where a drive is only present in a desktop docking station. /T -This option causes the driver to enable trace mode, where trace information is output to the OS/2 System Trace Facility. This option is only used to debug driver and/or operating system problems. Since the amount of trace information is voluminous, enabling this option can slow the driver down. This option is best left disabled. /P:xxx -This option forces the driver to believe that the Panasonic CD-ROM interface base IO port is at the specified address. This option is necessary if your CD-ROM interface board is not configured at one of the usual base addresses. By default, the driver will scan addresses 300h, 320h, 330h, 340h, and 360h. This option is necessary if, during installation, you are forced to choose the "Advanced Configuration" option. The following is an example line which enables the driver in verbose mode at address 450h: BASEDEV=SANYO001.ADD /V /P:450 These changes can be made with any ASCII text file editor. If you do not already have an editor with which you are familiar, you may use the OS/2 System Editor. Use the following procedure: 1. Select OS/2 SYSTEM. 2. Open PRODUCTIVITY. 3. Open OS/2 SYSTEM EDITOR. 4. Select File, Open, enter c:\config.sys 5. Scroll to the line where SANYO001.ADD is installed and modify it appropriately. 6. IMPORTANT! - Save the file (File, Save). ---------------------------------------------------------------------------- COMMON PROBLEMS "Drive not found" message If this message appears during system boot, then either the driver cannot find the Panasonic CD-ROM Interface, or your Sanyo CD-ROM drive is not physically connected properly to that interface. First, attempt to verify that the physical connection is correct, perhaps by verifying operation under another operating system such as DOS. If you are certain that the drive is connected properly, the next thing to do is to verify that the I/O port base address for the Panasonic CD-ROM interface is communicated to the driver. Note that the driver will automatically scan for the interface at I/O addresses 300h, 320h, 330h, 340h, and 360h. Consult the documentation that came with your CD-ROM interface to determine its base address. See the section of this readme titled "ADVANCED CONFIGURATION" and pass that address to the driver and you will be up and running. If the driver still cannot find the interface, then there is one more option, albeit unpleasant. If the driver had originally functioned OK, but couldn't find the drive the next time you turned the power on, that is a sure sign that your CD-ROM interface falls into this category. Some CD-ROM interfaces are packaged on sound boards where the Panasonic interface is not enabled at power up. These installations are distinguished by DOS config.sys files which first load a DOS device driver to enable the interface, and then load the actual Sanyo CD-ROM driver. You may boot from a DOS floppy that executes this first device driver, then do a warm boot via Ctl-Alt-Del to start OS/2 from the hard disk. The OS/2 driver will continue to see the interface until you power down. If your machine falls into this category, contact the maker of your CD-ROM interface board to have support for it added to this OS/2 driver. ---------------------------------------------------------------------------- ERRATA 1.
