we are lucky, I accessed my laptop (sorry I was 250 Km away from where I live, now I am back)
and I found a backup of the whole DVD which was included with the board when I bought it
good news: we have it
bad news1: it's mostly written in chinese and you need to sort things out(1)
bad news2: it's 4Gbyte
(1) even folder's labels are written in chinese
also there is a lot of confusion about the content
things come with no order
years ago I had sorted things out and focused on essential things
(schematic, constraints, examples, doc written in English, etc)
but then I deleted the folder since I don't use Altera
anyhow, here we go
