SCSI use in old Open Firmware versions
« on: February 07, 2019, 10:49:58 AM »
Hi Everyone.

I have been trying and failing to access scsi devices in Open Firmware 1.0.5.

Supposedly, I am supposed to do something like this:
Code: [Select]
" scsi-int/sd@0:" open-dev
I have tried so many variants of that line, and they either fail or hang the machine.

I am trying to either read disk blocks or run boot code from disk (like OSX does for OldWorld Macs).

Does anyone know about the internals of Open Firmware or how scsi is supposed to be used?

Thanks,
Daniel
