Package: yaboot

Severity: wishlist

Very recent versions of Open Firmware on Pegasos support yaboot, at
least for netbooting. It would be useful to be able to use ofpath to
find out the Open Firmware paths to disks on such systems. There are two
obstacles, at least on the development system I have which AFAIK is a
fairly standard configuration:
* ofpath doesn't recognise the Pegasos subarchitecture, and doesn't
know which style of device name -> Open Firmware mangling to use on
it. As far as I can tell, it's straightforward enough at least for
IDE disks (I can't test SCSI, unfortunately) that the same handling
as NewWorld can be used.
* The IDE disk shipped with my development system advertises its
device_type as "spi" (SCSI-3 Parallel Interface, I think,
http://www.openbios.info/docs/rec.scsi3pi.10.pdf - no idea why). The
Open Firmware path appears to be

Here's a patch for both these issues. If Ethan wants to merge this using
