Hello - apologies for the long turnarounds on this question, weekends is really the only time I get to try/test! :)
I did verify that both the C8000 and J6750 have DVD drives (DVD-RW in the former, DVD-ROM in the latter).
On the C8000, the SEARCH command in the PROM give the following model numbers:
POTENTIAL BOOT DEVICES
Path# Device Path Device Type
----- ----------------- -------------------------
P0 scsiA.6 HP 73.4GST373454LW
P1 ide.0 HL-DT-STDVDRRW GWA-4161B
I can’t really get to the old HP-UX install on the machine, so I don’t have more info on the drive itself - please let me know if more info on this model number is needed!
I did check to try and boot with no disc in the DVD-RW drive, and I did get an expected failure from the drive trying to boot - I am assuming the below is expected:
Main Menu: Enter command or menu > boot ide
Interact with IPL (Y, N, or Cancel)?> N
Booting...
Failed to initialize with ENTRY_INIT Status = -7
fffffff9 1 0 0
0 0 0 0
0 0 0 0
0 0 0 0
0 3 9 0
454e4841 0 0 454e4841
0 1b 51 20
3 51 20 3
.... FAILED.
I burned the NETINST image to a DVD-RW (4x Memorex disk, burned at the lowest 2.4x speed), however still no booting on the C8000 - same error on LIF magic. I then realized that the following needs to be followed on OSX for those who have tried to burn a bootable ISO for installation: https://discussions.apple.com/thread/5132196 - I also verified that this was not the issue previously, and DVD media is needed.
So now I have a successful Debian HPPA boot! Thanks to everyone for their help.
Now, right after the kernel finishes boot and it seems debian-installer is launched, the content on the serial console is all garbled! I am using the standard serial console settings suggested for the C8000 (9600 8n1) via the following GNU screen command line on OSX for an HP usb-serial dongle: screen /dev/cu.usbserial-FTBAWB7G 9600,cs8,-parenb,-cstopb,-hupcl
Thoughts?
Again - thanks to everyone for the time and help - have gotten this far, hopefully the debian-installer piece is straightforward! :)
