Here's the thing. Wine is useless when it comes to drivers. Why do you need to install the motherboard drivers? Frankly, if you got far enough that you could read the .exe files, I think it's safe to say the mobo is working.r As for audio, hope that your sound card is supported by linux, I'm guessing it should just work, if not, do some google searches with its model number for a linux solution.
Your driver disk? forget it. EXE files are useless. Either there's a specific linux driver, or there isn't, and sadly, right now the disks that come with computers assume you're using windows, the're really not useful with linux.
You need to radically change the way you think of software. In Windows, you download a file or pop in a CD, double click on it, and it opens an installer. Linux takes care of all this for you. In Linux, you use package management, which I believe is YAST in Suse (I'm not sure, I'm a fan of debian's APT). You will go there and select a package, such as wine, and it will install it for you. 99% of the time you will not download software from websites or install it from a file you downloaded, you will just let the package manager take care of it. (That changes once you start compiling software, but I think you need quite a bit more experience with linux before you try that.)
What drivers are you trying to install? Why do you need wine? If you're desparate enough to run windows within linux, take a look at Virtual Box at www.virtualbox.org
