You know you can download it without an account? Just say no/decline to the advertisement stuff when you do though.

I've downloaded many times from driverguide with the free option, never had a problem.

Apparently free downloads are only available using DrigerGuide's Installer, which my antivirus (Avira) rejects after downloading...

Disable avira until its downloaded. Its safe.

driverguide is full of spyware

Some of the programs they try and get you to install through their own installer might be borderline adware/spyware, but you have the option to decline all of this and just download the driver. I've done this several times and Microsoft Security Essentials and Bitdefender have never complained.

I wouldn't trust Driverguide either. Hell, I won't even go there anymore, much less download anything. They've always been a little sketchy, but once they moved to using all these installer programs and crap, they made their way onto my firewall's blocklist. If it looks like a scam and feels like a scam, even if there's no definite evidence to prove it, the smart move would still be to stay away.

I dug around in my archived stuff and turned up this file. I'm not 100% positive it's what you need, but the name and contents look about right. I know I used to have an Initio card of some sort, and from pictures I found online I think it probably was an INI-9100UW, so it would make sense that I would have a BIOS update for it. I just can't remember if I ever installed it or not.
