- SCSI Preferences for the Amiga 3000
- -----------------------------------
-
- by Martin A. Blatter (blatter@ifi.unizh.ch)
-
- This small program allows you to change the bits in the Amiga 3000's battery
- backed up memory that control some parameters of the embedded SCSI host
- adaptor.
-
- IT REQUIRES AMIGADOS 2.0 OR HIGHER AND AN A3000! It won't run on an A2000!
-
- SCSI Prefs is Public Domain. The entire risk as to the quality and performance
- of this programs is with you.
-
- Put SCSI Prefs in your prefs directory. It offers the same look and feel as the
- standard 2.0 Preferences editors, so you'll imediately find yourself familiar
- with its user interface.
-
- ---------------------------------------------- Long SCSI Timeout (Seacrate Mode)
-
- This checkbox determines how long the host adaptor waits for connected drives.
- It's especially useful for owners of drives that take a long time to spin up.
- Drives manufactured by "SeaCrate" are candidates for this setting. With this
- option enabled the controller will wait 2 seconds instead of 128 ms.
-
- (Some drives by Imprimis and Maxtor also need long timeouts)
-
- ----------------------------------------------------------- Synchronous Transfer
-
- When this option is enabled, the host adaptor will initiate synchronous transfers
- (hence the name of this option :-) with hard drivers capable of doing them.
-
- (Hard drives made by Imprimis, Conner Peripherals and Quantum usually support
- synchronous transfers)
-
- ---------------------------------------------------------- Support Multiple LUNs
-
- Each SCSI ID can support several Logical Unit Numbers. I can't think of a use
- for more than one LUN right now, but that situation can change...
-
- Leave this option disabled for now, beacause it apparently can cause troubles
- with hard drives that respond on more than one LUN address.
-
- ----------------------------------------------------------- Host Adaptor SCSI ID
-
- The Amiga (resp. its SCSI controller) is usually set to SCSI address 7. If you
- want to use a SCSI device with your Amiga that can't be jumpered to another
- address than 7 , you'll have to type in another number here. Be sure not to use a
- SCSI ID that is already assigned to device attached to your Amiga. (The internal
- Quantum hard drive is set to SCSI ID 6).
-
- The value of SCSI ID's can range from 0 to 7.
-
- Take care! If you experiment with SCSI ID's, always keep a copy of this program
- on a disk. Your hard drive won't boot if both, the Amiga and your hard drive have
- the same SCSI ID...
-
- --------------------------------------------------------------------------------
-
- All changes made with SCSI Preferences won't have an effect until you reset
- your Amiga.
