Looking for a VIA RAIO/SATA Driver for an Alienware PC?
Yeah, well I was too. Let me just say that it's not on their website and it takes a month for them to respond to email. The model I needed was the M5700 Series. Through googling, I found this site.
Which linked me to some German site that had a German 'i accept' box i could click and then download the driver.
If that link does go down, i re-hosted it here.
If you're having trouble installing the driver, because you don't have a floppy... try picking up a USB floppy drive.
