Do the I/O ports work on anything other than QTS?

Hi there, first of all, thank you for making this!

I myself have a QNAP TS-453D, with TrueNAS SCALE installed on it. I would like to make something like this, but for TrueNAS instead (since that's what I prefer, rather than QTS).

Looking at SIOPoller.cpp, there is kRegPort, how did you find out about this? (is this mapped in the BIOS? I've never done any of this, so I'd love to know.) And, is this valid, even though there's a different OS on it, or is this value purely for QTS? And is this the same for all of the ports, such as the portStatusLed and 0x91?

Hi,

You're welcome, thanks for your interest. The values were found by trial and error since I could not be bothered to try reverse-engineer gigabyte-sized OS images and megabyte-sized HAL binaries.

I believe it might be possible to make sense of some long text config files that describe these I/O ports distributed with the upgrade images, but last time I tried using this, it confused me more than anything else.

Anyway, this is already 2+y old and I forgot the specifics, but you can have a look at the Gist where I documented my research, which led me to write this here project. You'll find the config file I'm talking about. By extracting the official image for your specific model you might be able to find the right values.

Best of luck!

Thank you so much for providing this! I'll take a look at it. :)
