My PC don't find the sampler by the scsi.
I've 2 drives on the scsi card
Id: 2 & Id: 6
The sampler: Id: 5

Thank you for your help!!!

Have you tried this easy thing:

With the PC turned off.
Load the Sampler Operating System. Must be Version 2.0 if you want to use it with MESA.

When that is done,
Start the PC, hopefully it will find the sampler this time...
