I'm searching for this mobo driver, but seems I can't find it. If someone can find it for me or knows any link please tell me, thanks in advance.

My previous mb was a Soltek SL-65KVB, which is a similar board (same basic model with different Via chipsets).

Check the Via Arena Drivers page, pick your operating system, then in the next section that opens, the drivers you need.

After Soltek dropped support for my mb, these are the ones I used and they worked fine.
