For now the 2090a is toast. Two pins from the SCSI header on the motherboard are missing.

So it’s back to the dataflyer.

I see online their are dms install files for it. I guess that’s some sort of Amiga disk image.

I have a windows laptop with a 3 1/4 drive in it.

I hope theirs an app that can format and write the dms file.

All I want to do is find out what is Imon the hard drive.

Ok the 3.14 Rom chips, the USB drive and the SCSI2SD card arrived.

I have the Rom installed and the ADF images installed on the USB drive. All ok I can boot into 3.14.

Now I want to install 3.14 to the SD card and boot from my HD.

So I attached the SCSI2SD card to my 2090A, started the machine and nothing.

I also tried the Dataflyer controller. Nothing.

I must be missing something.

Any help appreciated.


Am I supposed to format the SD card on a PC first?

I used the checkconfig tool and the card was identified. I tried the format tool and the only thing recognized was DF0.

The 2090a is a bit non-Standard.

Check some online resources for installing AmigaOS on HD - it is completely different to how it works on a PC.

You need to configure the SD via the driver here:

I spend most of the day and it has not gone well.

Some times the SCSI2SD is recognized, some times it is not.

Is there a modern Amiga SCSI adapter out there?

Could you a bit more I to detail what you did?

Would be interested to see what we can do about this.

How did you
- set termination
- provide power to the SCSI2SD

And to answer your question: no newer SCSI that I’m aware of.

You might want to consider IDE: ... a-ide.html

I use the SCSI2SD a lot in classic Macs it is a great device but you have to configure it first. You can download the utility and the instructions at the SCS2SD site.

Sorry if you have tried that already but just in case you didn't.
