Greetings all, I've been lurking these forums for awhile, finally signed up and this is my first post, as I'm sure you can tell. I'm trying to understand my options for activating a little better. Basically, I've got four computers. Two desktops and two laptops, each of course running 7 Ultimate. The desktops are an older computer, from around 2000ish(I think?), and a Mac mini from 2006, dual booting with OS X of course. Both of the laptops are Dells. One is a Dell Inspiron 6400 from 2006, and the other is a Dell mini 10v from just a couple of months ago, which is running Snow Leopard as well. Right now, my understanding is the Dell mini 10v is the most "bulletproof" from becoming "unactivated" by SP1/WinACT whenever it should come around. I'm planning ahead I guess. For the 10v, if I recall correctly, I ran Daz' Windows 7 Loader and installed using the "Advanced Options". This is the part where I begin to get confused. Is this "Advanced Options" process modyfing my BIOS and thus making my Dell Mini 10v "bulletproof" (I use the term loosely)? Or does something else need to be done? Basically, I'd like to have a BIOS mod on all four systems, but I'm not really sure where to begin, especially with the older desktop and my Mac mini. Thanks in advance, Chris.
