-
- GENERAL
-
- This device allows you to use an ATAPI CD-ROM drive
- with the bsc/Alfa-Data IDE controllers (AT-508, AT-2008, AlfaPower).
- You can use the very popular and cheap CD-Roms for PCs.
-
- The device maps SCSI-II commands to ATAPI packets using the
- standard Commodore HD_SCSICMD interface, so any "CD-Rom
- specific" programs (Multisession Filsystems, Audio Players and
- Photo-CD readers) designed for SCSI-II CD-Roms should work.
- This has been tested with CacheCDFS, PlayCD, CD32-Emulator
- (all written by me) and PhotoWorX (an excellent PhotoCD Reader
- by Corporate Media).
- However, I cannot guarantee that every SCSI-II specific program will
- work, but I do not expect any major problems.
-
-
- COMPATIBILITY WITH EXISTING IDE HARDDISK
-
- Every (and I mean it!) IDE drive that works with the original
- oktagon.device WILL continue to work if the ad_atapi.device
- is installed. The reason is simple: My device will use the code of the
- oktagon.device (if present) to access the IDE harddisk.
-
- If you connect an ATAPI CD-Rom and you harddisk stops to work, this
- usually is a hardware, not a software problem.
-
- Check cables & jumpers.
-
- Some harddisks must be rejumpered, if a slave drive is connected.
- Consult the manual that came with your harddrive before doing so
- or ask your dealer for assistance.
- Make sure, the CD-ROM is configured as a slave device.
- Please consult the CD-Rom installation manual.
-
-
-
- TESTED DRIVES
-
- A couple of drives have been tested with the ad_atapi.device.
- The test configuration was an A4000/40 with and without Oktagon 2008
- SCSI controller, with and without an IDE Harddisk (Quantum Maverick 540
- or Seagate ST328A). The drives were selected always as the slave device,
- even if no IDE Harddisk was installed.
-
- Recommended drives (work 100%):
-
- Mitsumi FX-001DE (2x speed)
- (Don't mix this up with the FX-001D! The FX-001, FX-001D and LU005
- are NO atapi devices and will NOT work! Connecting a non IDE/ATAPI
- device to the Amiga IDE port may damage both your Amiga and your CD-Rom!)
-
- Mitsumi FX-300 (3x speed)
- Mitsumi FX 400 (4x speed)
- Sony CDU-55E (2x speed) <-- Audio play requires CacheCDFS 2.5 or better
- NOTE: The CD32-Emulator will only work with the Sony CDU-55E, if no volume
- control is enabled in the emulator's preference window.
-
- Wearnes CDD-120A (2x speed)
-
-
-
- TESTED FILESYSTEMS
-
- The device has been tested with the CacheCDFS (yes, this is written
- by me, too) and my PlayCD Audio player.
- It works very well with my CD32-Emulator.
- However, I don't expect any problems with other filesystems.
-
-
- INSTALLATION
-
- Installation is simple.
-
- Connect an IDE-ATAPI drive to your IDE port.
- You should jumper the drive as a SLAVE device, even if you do
- not have an IDE harddrive connected, as the Amiga may not boot
- if it encounters an ATAPI CD-Rom as the Master device.
- However, IF your Amiga does boot with a CD-Rom as the master
- device, you could use two CD-Roms at the same time.
- The unit numbers will be 0 (for the master) and 1 (for the slave).
-
- If you have an IDE harddrive, you should buy a standard PC-IDE
- harddisk cable, as the original cable is too short for both an
- IDE harddisk and a CD-Rom drive.
- The harddisk should be jumpered as the Master device and the
- CD-Rom as the slave, otherwise the Amiga will not recognize
- the harddrive.
-
- Copy the ad_atapi.device to your devs: directory.
- The supplied installer script will do this for you.
-
- Now you must tell your CD-Rom FileSystem about the device.
- This differs from product to product, please consult the manual
- of the Filesystem you wish to use.
-
- With CacheCDFS, simply run the CacheCDFS installation program.
- It will automatically detect your CD-Rom.
-
- A CD-Rom connected as the slave device will have unit number 1, which
- will be the common case.
- A CD-Rom connected as the master device will have unit number 0.
- The name of the device driver is ad_atapi.device.
-
-
- KNOWN PROBLEMS
-
- It is possible, that some drive models cannot be mounted after a reboot,
- because they need some time to wake up after a hardware reset.
- (On a PC it takes often a long time until the CD-Rom is accessed)
- This depends on how "fast" your startup-sequence reaches the mount
- command.
- If you have this problem, add a delay (e.g. Wait 3) before the mount
- command in your startup-sequence.
-
-
- That's it!
