But your hardware vendor should have supplied a CD with that driver. See discussions at http://www.google.com/search?num=20&hl=en&safe=off&q=windows+64+sis180&spell=1
I can't help you since the forum tip apparently is not showing. It read at one time the following: Tip: If you are asking for help to troubleshoot a computer-related problem, please be sure to include all the necessary information (ie: operating system, model number, hardware, software, etc) that will help others identify your problem for a speedy resolution.
i(legally) downloaded the trial x pro 64 bit edition from microsoft, burned the cd, and tried to load it on my computer. the setup loads the first set of items, then asks me where to install it, so i push 's' to select a new location, load the 'windows64 sis180' drivers from a floppy i made, then the setup says starting up windows, and it freezes right there. any help?
