Hmmm unfortunately my joy was short lived. I managed to get one proper boot out of the system on BlueSCSI but now have massive disk corruption. Even after fsck'ing the whole thing it refuses to boot into the UI and just drops me into a console mode with Getty errors etc. Need to start over.
So, I am trying the SCSI2SD approach again. I flashed it onto the SCSISD again, put it into the Quadra and booted from the Silverlining floppy. Now the strangest thing happens which might explain why it is not working... I see 3 SCSI IDs while only 2 are configured on the SCSI2SD. Verified using different boards...
Anybody see this before? The 3 SCSI disks are all invalid according to Silverlining and it is unable to repair. When I check the disk in my Mac I can display the partition table without issues.
Fun install this is... even AMIX from tape on my 3000UX was easier
