I'm lost, there is so much information on this website it is hard to wade through. I'm not exactly a newb, but I still have a question. I have searched all night, and used google to no avail. I have a acer laptop, an aspire 5735 I'm trying to install W7 on. It has slic 2.0. I need slic 2.1. I have the phoenix tool, and know how to run it, but the certificate doesn't verify, because the original BIOS is slic 2.0. How do I upgrade the bios to 2.1? Or can I ignore the warning stating the certificate doesn't match? I've done this several times before, but had more modern motherboards with slic 2.1. Sorry to be such a newb, I just need a point in the right direction. Thanks to you kind folks helping so many users with this. -stubbs.
