SCSI to IDE bridge installation to A4000

I thought I'd make some use of the GVP SCSI card that I have and put it into my A4000. It isn't the best solution available but it still beats the onboard IDE. I found a relatively cheap SCSI to IDE bridge from the other bay. I currently have a CF IDE adapter in card bracket, making the CF card easy to move for file transfers.

Now, when I started to put things together , I hit couple of snags:
The GVP card is a full length card so it is a bit of a pickle to fit into A4000. I really have to remove my Retina card before I can get the GVP to seat in the Zorro slot.

The SCSI to IDE bridge on the other hand is of type that plugs right into a back of a hard drive, having a female connector. It plugs nicely into the CF IDE adapter but you can't get this combo to fit in the card slot. It seems that I have to get a custom IDE cable with male and female connectors. I have another CF IDE adapter that doesn't go into card bracket but I'd then miss the easy access to the card.

Now, obviously my setup is set for the SCSI.device, which controls the IDE. What do I need to do to change it to SCSI? I have also a SCSI CD-ROM. Probably a good idea to change that too.

I rearranged the cards over today. The SCSI card is now next to the CF IDE adapter. Too bad the the IDE connector on the SCSI IDE bridge is oriented the wrong way. Otherwise it would have beena nice and neat setup. Now I have to put a custom cable, that I ordered from Amigakit, in between.

There's quite a lot of twists and turns on that SCSI lead. :D

If it's a GVP SCSI card, you'll probably be wanting to use gvpscsi.device :-)

Thanks for the tip, AndyLandy! I am indeed using a GVP 2000 HC+8.

One thing worth mentioning is that my SCSI-IDE bridge is an R-IDSC one. I've taken the time to study, how to set up the jumpers on that. What I still need to do is to set up the ID and termination on the CD-ROM drive - and to figure how to get the gvpscsi.device in my A4000. I'm currently a bit short of methods for transfering files between computers.

You plug the GVP SCSI card into a Zorro slot. That's all there is to it. gvpscsi.device is loaded off the autoboot ROM on the card. Huzzah for autoconfiguration!

So it seems. :lol: Thanks!

Forgot that I'm still missing one cable between the SCSI-IDE bridge and my CF-IDE adapter. Hopefully, that will arrive along my ZorRAM card.

I got the missing cable now. Tried booting from floppy and opened HDToolbox. It can't detect the GVP SCSI device. In bootup, the A4000 goes to insert WB screen after 30 seconds or displays the black screen infinitely, if boot jumper closed on GVP. The memory on GVP displays ok. The R-IDSC should be properly jumpered so that it doesn't terminate and is recognized as hard disk. The CD-ROM, which is last in chain is terminating.

Is there any other jumpers on GVP I should try? :help:

I tried changing to the gvpscsi.device in hdtoolbox icon but it still can't see the CF card.
i could really use some help here.

Just to lay some ground checks..., you may have answered them already..

Bridge needs 4 pin molex power (HDD Connector), CF adapter will need Floppy type connector.

Bridge jumpers

1, 2, 3 are SCSI ID, this must be UNIQUE
4, 5, 6 SCSI 1/2 select.
7 PIO/DMA
8 Flash Rom Reprogram mode.
9 Termination ON/OFF

My own jumper for my R-IDSC.

1 OFF, 2 OFF, 3 ON (SCSI ID 4)
4 OFF, 5 ON, 6 OFF (SCSI-2, as I used a CyberSCSI MK II).
7 ON (DMA)
8 OFF (Flash protect)
9 OFF (Default, Termination on).

@whiteb
Looks like I have to gather up an extra jumper somewhere. I have 5, 7 and 9 jumpered as the bridge isn't terminating but I have no jumper for defining the ID. Thanks for that!
