If you add CD-ROM drives after having installed CDT, you must open the CD-ROM ToolKit Control Panel and check the boxes next to the drive ID of the new CD-ROM drive, because you need to tell CD-ROM ToolKit to support those devices.
Likewise, if you change the SCSI ID of your CD-ROM drive after having installed CDT, you must open the CD-ROM ToolKit Control Panel and check the boxes next to the desired new SCSI ID.
CD-ROM ToolKit will display a question mark icon upon startup if it has not been configured to support any CD-ROM drives.
Photo CD
--------
Users should install QuickTime 1.5, or newer, to maximize usefulness of Photo CD on the Macintosh. QuickTime 1.5, or newer, is required for System 6 users or else PhotoCD disks will be ejected and never mounted when using "Apple Photo Access". Keep in mind that QuickTime does not operate on "68000" computers such as the Macintosh Plus, SE, Classic, Portable, and Powerbook100. The latest version of QuickTime is 1.6.2.
Apple Photo Access
------------------
"Apple Photo Access" is a system extension file from Apple that will allow the Finder to present nice looking icons and folder structure on Photo CD media. Macintosh systems without that extension can use Photo CD, but its absence makes it impossible to use the Finder to browse photographs and select photos to load. This means you will need at least some type of Photo CD compatible graphics program to view Photo CD pictures. This file is only available directly from Apple or by downloading from information systems such as AppleLink. Users of Photo CD should obtain this file to make Photo CD access more Mac-like. You can download this software from AppleLink from the following path:
Software Sampler
Apple SW Update
Macintosh
Peripherals
Macintosh CD-ROM Setup 5.0
It can also be found on the QuickTime 1.5 CD, the September 1993 developer CD, and at Apples INTERNET address "ftp.apple.com". As of September 1993, only version 3.2 of Apple's CD-ROM driver disk (lacking "Apple Photo Access") was on America On-Line and Compuserve.
Multi-Format CD-ROMS
-----------------------
CD-ROM ToolKit has a unique capability of mounting CD-ROMs that have both Macintosh HFS and ISO or ProDos formats. You need to open the CD-ROM ToolKit Control Panel and enable this through the Options button. CD-ROMs that are ISO9660 format but also have Macintosh HFS partitions need special care when being ejected. The current version of CDT requires that the ISO9660 partition be unmounted BEFORE the remaining Mac HFS partition is unmounted.
Early Apple Developer CDs (Volumes 1-7)
------------------------------------
These contain both an Apple II ProDOS partition and a Macintosh partition. To mount the ProDOS partition, you need to have the ProDOS File System extension in your System Folder, and the ProDOS mounting option enabled in CD-ROM ToolKit's Control Panel. This file is part of the Apple IIe card software for the Macintosh LC family. You can download this software from AppleLink from the following path:

Pre-Scanning System 7 Alias files and Color Icon files
-------------------------------------------------
Enabling Pre-scanning System 7 Alias files and System 7 folder icon files options can easily result in exhausting all caching buffers. Many of the CD-ROMs that contain color icons have hundreds of them that occupy a lot of cache space and require lots of pre-scanning time. By default, these two caching options are not enabled. Be aware that enabling these options may result in extremely long pre-scanning times and filling of all cache buffers.
Low Hard Disk Free Space
-----------------------
If your startup hard disk volume is heavily fragmented and nearly full, preventing creation of the standard 3 MB cache file, CD-ROM ToolKit will attempt to allocate less disk space to the disk based cache file. Users can always free up disk space, delete the FWB CD-ROM Cache file from the Preferences folder inside the System Folder, and restart to force recreation of a larger cache file.
Adjusting CD-ROM Ram Cache
--------------------------
For no dynamic RAM cache except the prescanning static cache, set to 232K, otherwise
set from 300K to any large desired value.
Adjusting CD-ROM File Cache
--------------------------
The file cache size can be changed at any time, but changing it after the cache file has been created will require the user to trash the FWB CD-ROM Cache File from the Preferences folder in the System Folder and restarting to allow creation of one at the new size. The size can be set from 1500 to 5000K.
Known Incompatibilities :
-----------------------
There are no reported incompatibilities.
Remember:
----------
Please remember to unmount all ProDOS and ISO9660 partitions before unmounting the last normal Mac HFS partition on CD-ROMs that contain more than one partition.
Playing Audio Tracks:
-------------------
Our player (and other's) will not allow you to play the first track on most multimedia disks because that first track is not an audio track… it is a computer data track. There is no problem regarding this except for the confusion it may create. Renumbering the tracks to hide the first data track is not an honest solution, but would have eliminated the problem. Some multimedia CDs containing audio tracks include : "Battle Chess" and "Just Grandma & Me".
Using True Multimedia Titles
--------------------------
If a CD-ROM's installation manual instructs you to run a copy of the program from your hard disk, do so. True multimedia titles use digital audio tracks as well as information stored in files. There are few of these titles in existance. One reason is because the user must setup audio output from the CD-ROM drive, usually with headphones or an amplifier. The other reason is because most of these titles suffer small audio quirks on non-Apple drives without a flawless CD-ROM driver such as FWB's CD-ROM ToolKit. But there is a third reason that they are rare. Audio output can sometimes be inadvertantly stopped due to requests for file information. Any request for information from a file must immediately cancel whatever audio was playing because the CD drive must fetch it. The best solution is to move the application and its key files from the CD to the hard disk before starting. An example of a multimedia title that could be affected includes "So You Want to be a Rock and Roll Star?".
Reminder to avoid Vitual Memory
------------------------------
Apple's implementation of virtual memory adversely affects many titles that "play" sequences of images or sound from a CD-ROM in a sustained manner. The reason is because many applications assume that large amounts of RAM memory exist without realizing that this memory is "virtual" and actually stored primarily on a storage device. The symptom is choppy audio, reduced video frame rates, or video "jerkiness". You will want to avoid starting the computer with virtual memory enabled when running many QuickTime based CD-ROMs if the applications suffer from jerkiness on your system. This problem is common to any CD-ROM driver product, and CD-ROM ToolKit is not a factor.
Helpful Hint for Interactive Titles
-------------------------------
There is a way to get additional performance. Many interactive CD games are built using Macromedia's "Director" program. It has been observed that many of these titles prefer to have as much memory as possible allotted to them. Copy the main application to the hard disk and set the amount of RAM allotted to the application to a much larger value, but not all the memory. Your performance should increase, though not dramatically.
