Hi all, I've been reading the stickies but there's something I just don't get, so I decided to sign up and ask. But, let's go in an orderly fashion, first the story, then the questions. I ordered a Samsung NC10 for my wife. While it is on its way, I thought it would be a good idea to figure out what to put on it instead of that lame XP Home, so I asked my friends around about Windows 7. They said it will work fine, but they did not recommend the 64bit version and I should probably stick with the x86 version (Question #1: Win7 64bit or x86 for a Samsung NC10?). I thought I could give Windows 7 a go, but it's not available yet, so I kept asking questions about keys and activation from my friends and I ended up on this forum. I found some threads and stickies about NC10 and Win7 activation, BIOS modding, etc. I concluded that since it's a laptop, I might be better off with a BIOS mod than installing a hack every time MS decides to update a DLL to delay the inevitable. Anyway, there is something here that I do not understand. I understand, OEM is meant to be an offline activation method, not requiring any user interaction - only a disk, the appropriate BIOS and a serial number. And that brings us to question #2: say, I have the OEM disk, I have the SLIC 2.1 BIOS, an OEM key and I do a clean install (formatting the drive): why do I need to install a certificate and use 7loader when it should work just fine? Could someone clarify this? Thank you.
