The ST will boot from the SCSI bus so any driver normally lives on the Hard Drive and is loaded via the boot.

That is an ICD adaptor and so needs the special ICD software. As this was saleable I have three suggestions: -

1. It was just binned as someone didn't know it was valuable.
2. It was sold as it was valuable
3. He used a hooky copy.

The ICD web site is up but no products are available.

I thought there was a copy on the Atari Archive at UMICH but it appears not.

but the standard Atari software is available there. I think it works with the ICD adaptors.

The only available driver is that from here:-

which is really good. The demo will at least see the SCSI IDs...

most Atari action now takes place on the Atari Forums, which I never look at these days. Google it...
