Astaro 110 reinstall

What ISO are you trying to put on it?  Are you using the software or hardware ISOs available?

the only ISOs I can find for download are 9.x, which seems too advanced for a VIA processor with 1GB RAM max. Information on the interweb says 8.x is the latest possible install.
Anyway the DVD starts reading and then skips the DVD to an empty SSD and an error …

It may be an issue where you cannot install UTM on that device.  That's an extremely old hardware appliance, and doubtful you could, or even want to, install even v8 on it, let alone find the ISO for it (unless you've had it already or have a friend that does).  It's been updated for very good reason - the security vulnerabilities alone make it that way.  Not saying it isn't possible to load it - just slim chances.

Does it have a USB slot where you can try an ISO install that way, or just the DVD?  And again, are you using a hardware appliance ISO or the software appliance ISO? Does your internal SSD have UTM on it already?  Part of loading a home license on a hardware appliance requires some telnet into the device and changing something to make it work.

What is the error you are getting after trying to load?

You can set the BIOS to boot from USB CD, USB ZIP and the internal harddrive is new and empty. Both the hardware DVD and the Software DVD do not load, the ASG skips the DVD and stops at the error "does not contain an OS, insert a valid OS and press enter", which is to be expected, as the SSD is factory new and empty.
Maybe I need a more recent Appliance or an alternative firewall build …

Hallo Michael and welcome to the UTM Community!

If the drive is not t original one from Astaro, you will need to install using a software ISO - the appliance ISO will not install.
