First off, just a quick thanks to everyone who has posted hacking information here...it has been extremely useful in making my webplayer a functioning, behaving pc. So, um, thanks!
I took the laptop HD route, but nonetheless my installation is working pretty well. Sound and video work, and there are no more unknown devices lurking in device manager. My sole problem right now seems to be a very flaky USB ethernet adapter. I can get it working, and it will work fine, but when I reboot, it will stop doing anything(no link lights, no connection, etc.). The Webplayer recognizes the adapter's there, it just refuses to turn it on. I have to uninstall/reinstall the adapter as well as USB drivers for it to work again(for a while, anyway).
It's the $37.50 2202USB/ETH from outpost.com, similar to what everyone else seems to be using. I used the drivers from the floppy, threw them on the HD before it got ported over. I'm not entirely sure why it is being so uncooperative. It works just fine on my main box, so I'm inclined to think it's the USB driver...
Has anyone else had similar problems? I'll keep poking at it, but if someone has any tips, I'd be happy to hear them. :)
