Wingzero thanks for the great guide. I have read the whole thread and it seems you have it all covered. I currently have an Aspire One which had a ZIF HDD added in place of the stock SSD but that broke on my trip to Rome for the champions league final in May. Since then I have been running OS X from an external HDD. My AAO runs OS X perfectly except for sleep. Has full QE/CI, Ethernet, swapped wifi for a Dell 1390, everything basically. But no sleep has been a constant bug. I'm also a mod over at aspireoneuser.com and I am resident in the OS X section and have been since it started so I have seen all the developments...
And... since I am getting paid thursday I thought I would get a nice new laptop instead of my current contraption. And a look around led me to the NB200. My first thought was does OS X work on it. And lo and behold, I stumbled upon your great guide.
So I think I'm going to buy mine come Thursday

A few small questions,
1. Does sleep work for you on closing the lid and does it reactivate on opening the lid?
2. Does audio automatically switch to headphones if you plug them in? If not, as I think it doesn't based on my reading, have you tried using a HDAenabler.kext and the stock AppleHDA.kext This is what we use on our AAO's and it gives autoswitch wheras VoodooHDA does not. Alternatively you can use soundsource, which I use on my Dell 530 hackintosh desktop as autoswitch doesn't work on that.
3. Do the indicator lights on the front work with OS X?
Also, if you do happen to disable the wifi and it wont turn back on, you can usually boot an installer disc and enable it from there. I had the very same problem with my AAO in times gone by and I was always reinstalling before I worked this out. Also, if you install teh compatible card in the machine before you reformat xp and install OS X, it must be enabled or OS X won't recognise it.
Finally, I think I might try out a bit of Snow Leopard and make a guide, but till have to be a huge amount of work to beat this immense guide you have made. All I can say is thanks in advance. And I suggest a donation button in your sig, I'm sure everyone would be able to donate a few pennies and every little helps for those addons like bluetooth and Dell 1510's...
