Tango 2 without drivers installed is hanging my 6360 during Happy Mac phase of boot. Does that make any sense?

It's Alchemy Architecture, not Gazelle in which this card is problematic without the Great Gazelle PCI Fix.
Makes no sense to me unless some PCI equivalent of DeclROM in a NuBus Mac is present?

Any suggestions?

it takes 2 to tango for sure. idk what you're asking.

Sonnet Tango 2 is a combo USB/FW card incompatible with TAM/5500/6500 Gazelle architecture machine unless the fix is applied. It should be good in my 6360 and 6400 Alchemy architecture machines, along with the 5400, which I'm happily not dealing with ATM.

Why is it preventing full boot and might installing the drivers take care of the problem?

The Gazelle PCI Fix applies to the Open Firmware phase which is before the Happy Mac phase.

Is Happy Mac phase before the part that lets you press the shift key to disable extensions?

Check the Open Firmware phase by connecting the Power Mac 6360 to another computer via serial cable.

We can extract DeclROM from the ROM if we have a ROM dump.
Which ROM does your Power Mac 6360 have?
Get the 64-bit checksum and see if it matches a known ROM.

We can check the PCI devices are discoverable using lspci for Open Firmware.

We can verify that probe-all succeeds by changing the nvramrc script. Type nvedit, enter these lines:

install-console
cr
." stack:" .s cr
." [ probe-all" cr
probe-all
cr
." ] probe-all" cr
." stack:" .s cr
banner

Type Control-C to end nvedit. Then type nvstore to save the changes.
Enable nvramrc script by typing setenv use-nvramrc? true
Reboot.
If it works correctly, you should see the probe-all message before and after probing, and the stack before and after probe-all should be unchanged.

Depending on your ROM, we may need to change the install-console word.

We can use the dump-device-tree and lspci info to add emulation for the Power Mac 6360 in DingusPPC. That might be helpful in debugging stuff.

It should be the same as a 5400 or 6400 joevt. Same board.
