HPPA support for IGNITE-UX install discs

[Keith Monahan]

HI there,

In QEMU 5.1.50 (also tried 4.2.1) built from source, I have a particular 
IGNITE-UX disk associated with an HP Logic Analyzer 16700A that I'm 
trying to boot and install. It's based on HP-UX 10.20. The regular LA 
hardware shows up via uname as "HP-UX no_hostn B.10.20 C 9000/779 
2008038539 32-user license" I've seen reference to 9000/779/rock. This 
should be fairly similar to the B132L/B160L.

While SeaBIOS identifies the attached virtual drive, and the specified 
CDROM boots, the install init script fails to find any IO devices, and 
so no installation can occur.

Other HP-UX 10.20 Ignite-UX disks work without issue in the same qemu 
environment with the same command line options.

A successful run has the "Scanning system for IO devices..." take a few 
seconds, followed by a "Querying disk device" message for each of the 
devices it sees. That whole process takes 30 seconds or so in emulation.

A bad run immediately goes from "Scanning system..." to "There were no 
disk devices found during the scan."

I have noticed that the "install/init" Revision on one that works is a 
10.3, but the failing one is 10.124. Not sure if this telltale or not.

Anyone super familiar with this type of install disk? Or how the boot 
process works with HP-UX CDs in general? What gets loaded first? How can 
I find this script and/or executable that's evaluating the readiness of 
the drives? My thoughts are that I could "update" via editing the ISO, 
which both mount easily in Linux.

But I'm open to thoughts, including redirection to a different more 
appropriate mailing list! :)

Thanks for any general advice.
Keith


I'm invoking like this:

./qemu-system-hppa -boot d -serial mon:stdio -drive 
if=scsi,bus=0,index=6,file=./hpux.img,format=raw -D /tmp/foo -nographic 
-m 512 -d nochain -cdrom ./HP16700_cdrom.iso -net nic,model=tulip  -net tap

and see this:

  Primary boot path:    FWSCSI.6.0
  Alternate boot path:  FWSCSI.2.0
  Console path:         SERIAL_1.9600.8.none
  Keyboard path:        PS2
