baffled .. the 2019-01-27 debian-10.0-ppc64-NETINST-1.iso not bootable
So here is further odd behavior. At this point I am just going to dig in
and keep plugging away here.
I fetched from :
https://cdimage.debian.org/cdimage/ports/2019-01-27/debian-10.0-ppc64-NETINST-1.iso
Then checked the SHA512 and burned that to a DVD-RW.
All seemed to go well.
Except in the other PowerMac G5 this dvd is not bootable. Nope.
So I took that dvd-rw back to the machine that did the burn process and
thanks to the great software from Jorg Schilling I read the iso image
back in from the dvd-rw media and everything matches perfectly :

Well damn.
So the dvd is flawless and won't boot. No idea why.
I can try it on a PowerMac G5 quad unit and see what happens however the
other netinst I had from 2018 seemed to work fine everywhere.
I will try this on an different G5 and see what happens.
If that doesn't fly then I will try the image from 2019-01-26.
