Offline Diagnostic Environment (ODE)
Offline Diagnostic Environment (ODE) is a an environment to test HP PARISC or IA64 hardware.
It is usually distributed as ISO image, which contains a LIF image with ISL + ODE binary + other data.
To boot it in qemu, it is sufficient to boot the ISO file.
HP provides some documentation about ODE at https://support.hpe.com/connect/s/product?language=en_US&kmpmoid=4284216

Booting ODE
qemu-system-hppa -boot d -machine machine -cdrom HP_ODE_CDROM.iso
Make sure to use either B160L or C3700 as machine parameter since ODE will decide at runtime based on the found machine type which test programs it will enable.
This will boot to ISL:
HARD Booted.
ISL Revision A.00.44 Mar 12, 2003
Cannot find an auto-execute file. AUTOBOOT ABORTED.

Typing ode will start the diagnostic environment. It is possible to start a specific test by adding it to ode:
ODE L2DIAG
will start the PCXL2 CPU tests for the PA7100LC CPU in the B160L. You will be asked for a password, in qemu it's usually 'quality', but can be 'poultry' or 'saturn' as well.

diaginfo provides some useful information:
L2DIAG> diaginfo L2DIAG is the PCXL2 ODE based diagnostic program. It is intended to test the processor of the various PCXL2 based systems in the offline environment. The program consists of 119 sections, 1/119, and are organized into the following groups: 1. CPU data path tests, Sections 1/6 (6 sections) 2. ICACHE tests, Sections 7/10 (4 sections) 3. DCACHE tests, Sections 11/17 (7 sections) 4. 2nd Level Cache tests, Sections 18/21 (4 sections) 5. TLB tests, Sections 22/27 (6 sections) 6. CPU instruction tests, Sections 28/76 (49 sections) 7. CPU extended tests, Sections 77/88 (12 sections) 8. Floating point tests, Sections 89/119 (31 sections)
A test or range of test can be selected by 'section X or section X/Y' where X is the starting test number, and Y the ending test number. If only X is specified, only test X is run.
