I am trying two add a second ST-296N SCSI drive to my TRUMPCARD , which is at 2.0 with the autoboot ROM Rev. 4.6. This is on an AMIGA 2000. (1) Both drives are external, mounted in one box. (2) Which drive should come first on the DAISY CHAIN ? The old one which is WorkBench or my new one which is just formated. (3) Do you need terminators on the last drive? The ribbon connects TRUMPCARD —–> Drive A —–> Drive B (last) (4) Does the SCSI ID's matter? I have tried every combination? Or is there a problem the TRUMPCARD? Any and all help will be appreciated.

Allan, The order of the drives (in terms of SCSI ID) doesn't matter. It does matter significantly that the two drives are configured for _different_ ID's, though. Also, it is important that the last drive on the cable (physically last) have the terminator resistors installed and that the other drive NOT have the resistors installed. I have no experience with the Trumpcard myself, so I can't help you with the details of configuring the driver software or the RDB's (if it uses the standard RDB). Hope this helps…. …BobR

The problem was the Device field which holds the Physical Device Name of the partition, in my case the complete volume. The old HD created under an older version of IVS TC Utilities did not really use this field, the new verion does and so incompatibly. The bottom line is I'm up. One for my Amiga and the other for my bridgecard AT. Thanks for your response. That goes for Betty Clay and Bill Leach a well. [AB] {"coming from knowing, nothing can be discovered"}

Glad you got things working. …BobR

Allen, I know that the last drive has to have a terminator, but I really don't know a great deal about adding drives to the system. You will get much better information from Don Curtis about that. I simply have not had the opportunity to work with more than one drive yet, and Don does it all the time. Betty

Allan; Not up on your question so forgive me if my comments are "off base." From Bob's answer to you, I am presuming that you want to add another HD to an Amiga. I don't know much about the Trumpcard (heck, what do you know Bill?), but some controllers are particular about the device unit numbers. In particular, the GVP controllers do not want you to skip numbers. If you are having trouble, that may be one thing that you should consider (BTW, it won't hurt anything if you do skip numbers and the controller insists that you don't… the drive just won't be recognized). As to termination resistors… There should be one set of terminators on each chain of drives. For most controllers that means that there should be a set of terminating resistors in one and only one drive. With some controllers, there are two different connection points for drives… and this is where things get tricky if you don't have the controller's manual: For instance, the CBM 2091 has two SCSI connectors but only one of the drives should have a terminator (the last drive on the external connector). The Kronos OTOH should have a terminator on one of the internal drives and a terminator on one of the external drives. An Amiga message processed by Whap!, bill
