Hi,
I must be doing something wrong here and need some hints
to figure out what.
My attempts to burn macppc install56.iso to a CD seems to
produce un-bootable discs. I'm using cdrecord(1) to perform
the burns.
At the Open Firmware prompt I issue:
0 > boot cd:,ofwboot /5.6/macppc/bsd.rd
and that results in:
DISK-LABEL: read of block0 failed
ATAPI-DISK: open of DISK-LABEL failed can't OPEN: cd:,ofwboot
Can't open device or file

I went through four different burn attempts; one with Dec
7th snapshot. And three right now with Dec 8th one.
I tested with official 5.6 CD and that CD boots just fine.
This is how the image was burned to disc:
# cdrecord -v dev=/dev/rcd0c install56.iso
cdrecord: No write mode specified.
cdrecord: Assuming -sao mode.
cdrecord: If your drive does not accept -sao, try -tao.
cdrecord: Future versions of cdrecord may have different drive dependent default

Note the "WARNING".
Also note that burning an amd64 image works just fine
(with same "WARNING" during cdrecord phase).
On a related note, how can base tools (cdio(1)?) be used
instead of cdrecord(1) (from ports) to burn these images
to disc?
Thanks in advance,

Hi,
What happens when you hold the 'c' key during reboot?
If you mount the disks under a working system is ofwboot in the / ?
