- Using ATAPI CD-ROM drives with AsimCDFS
-
- The following are notes on our ATAPI CD-ROM driver software driver,
- asim_atapi.device.
-
- ATAPI stands for AT Attachment Packet Interface. It is an extension
- to the common ATA/IDE interface (used in both the Amiga 1200 and
- Amiga 4000 computers) to allow the connection of CD-ROM drives.
-
-
-
- 1.1 Requirements
-
- In order for an ATAPI CD-ROM drive to work, you will need to meet
- the following requirements:
- - an Amiga 1200 or Amiga 4000 machine;
- - an ATAPI CD-ROM drive;
- - AsimCDFS v3.5, or higher;
- - asim_atapi.device.
-
- Please note: our asim_atapi.device ATAPI CD-ROM driver will work
- only with the built-in ATA/IDE interface found on the Amiga 1200
- and Amiga 4000. No other ATA/IDE interfaces are currently supported.
-
-
- We have tested a number of ATAPI CD-ROM drives. These are listed in the
- CD-ROM_Drives file on the AsimCDFS install disk. Please note that the
- CD-ROM drive that you pick MUST be an ATAPI compatible drive. A few
- manufacturers have released so-called IDE CD-ROM, though they in fact
- use proprietary interfaces. If you have any questions about a particular
- CD-ROM drive, please feel free to contact us.
-
-
- AsimCDFS v3.5 has an extra addition to the CD-ROM Model option -- select
- the "ATAPI CD-ROM" option when using this asim_atapi.device driver.
- Note that this will selected automatically by our automatic installation
- procedure.
-
-
- NOTE: At this time, the ATAPI CD-ROM driver does not support autobooting.
- Expect this to be corrected in an upcoming version.
-
-
-
- 1.2 Installation of the ATAPI CD-ROM Drive
-
- The ATAPI CD-ROM drive will connect directly to the internal IDE bus
- on the Amiga 1200 or Amiga 4000. Two steps will be involved in doing this:
- setting the configuration of the devices, and connecting the cable.
-
-
- IDE and ATAPI devices can be set to one of three different configurations:
- - Master
- - Slave
- - Master with Slave Present
-
- Usually jumpers or dip switches are used to set the configuration.
- Your hard drive may be labeled with the jumper settings. Otherwise,
- consult your hard drive manufactuer for instructions on how to properly
- set the configuration.
-
- As a maximum of two devices can be connected to an IDE bus, your
- configuration will fall into one of the following three catagories:
-
-
- 1.2.1 1 hard drive and 1 ATAPI CD-ROM drive
-
- The hard drive will be set to "Master with Slave Present".
- The CD-ROM drive will be set to "Slave"
-
-
- 1.2.2 1 ATAPI CD-ROM drive only
-
- The CD-ROM drive will be set to "Master"
-
-
- 1.2.3 2 ATAPI CD-ROM drives
-
- The first CD-ROM drive will be set to "Master with Slave Present".
- The second CD-ROM drive will be set to "Slave".
-
-
- After you have set the configuration jumpers on the CD-ROM drive and
- hard drive, you will then have to connect the CD-ROM drive to the
- IDE cable.
-
-
- The Amiga 4000 usually ships with an IDE cable that contains an extra
- connector. To make sure you have the correct cable, trace the ribbon
- cable as it comes out of the IDE hard drive. The cable is usually
- notched or keyed on one side of the connector. If it is not, then
- a small arrow will be present in one of the corners - this will be
- pin #1. Align the notch or pin #1 with the CD-ROM drive and press the
- cable together.
-
- The Amiga 1200 requires the use of a special 44-pin to 40-pin cable.
- Your local Amiga dealer should be able to provide you with one.
-
-
-
- 1.3 Audio Connection
-
- The Amiga 4000 has a 3-pin connector located at the far left hand
- corner of the motherboard (when looking from the front of the computer)
- which allows you to connect an internal audio source and have it
- mixed into the Amiga audio and routed out through the RCA jacks.
- You may wish to connect the audio from the back of your CD-ROM drive
- to this connector.
-
-
-
- 1.4 Installation of AsimCDFS
-
- The installation procedure for AsimCDFS includes an option for ATAPI
- CD-ROM users. Choose "ATAPI CD-ROM on A4000/A1200" for the first
- question. AsimCDFS will then automatically install the asim_atapi.device
- ATAPI driver to your system and enable the SCSI Inquire program to
- access it.
