Hi Takashi,
sorry for our late reply.
1. INT203
Yes, we can confirm that the latest INT203 firmware has the model ID 0x6,
same like the INT202. Older INT203 firmware has the model ID 0xa.
At the snd-dice module level, there is obviously no difference, because
the hardcoded capabilities (modes/rates) are the same.
The only drawback is that when connecting the INT202, users see two
channels of input. But maybe this could be easily solved with an alsa
card profile.
2. DAC1
The DAC1 with model ID 0x5 that you found in the libffado configuration
file is not same the DAC1 that you found on our website.
That was an experimental device which included an embedded computing
board, connected via FireWire to an internal DICE-based soundcard.
This device was never released to the market, so I suggest discarding
this entry.
On the other hand, the DAC1 from our website was indeed sold with a
FireWire option. However, this is just and INT203 embedded inside the
DAC1, with no special ROM. This means that when connecting the DAC1 via
FireWire, it will present itself like an INT203.
I hope this answers all your question, otherwise let us know!
Kind regards,
Michele Perrone

Hi Rolf and Michele,
I'm working to fulfill hardware database of systemd project[1] for Weiss models with received
collection of configuration ROM, then have some issues. I would ask you to provide information
to solve them.
This is the table of the value of model ID field and model name.

I have two issues.
1. INT203
The modalias table in ALSA dice driver[2] includes 0x00000a for the model, while the configuration
ROM includes 0x000006. Michele wrote commit comment for it[3]:
```
Note: the INT203 presents itself as INT202, because the firmware
running on the two devices is the same.
The difference between the two lies in a jumper setting
inside the device.
```
In my opinion, there are multiple hardawre revisions for the model.
2. DAC1
When committing to hardware database of systemd project[4], I referred to libffado2 configuration
file[5]. It includes `DAC1` with model ID 0x000005, while it is neither found in ALSA dice driver
nor the collection of configuration ROM. As long as searching DAC1 in website of Weiss Engineering,
I can see DAC1-mk3 has option card for IEEE 1394 connection[6]. Would I request you to provide
information about the model?
