The subject has been totally resolved. Please read all the posts on this tread. Hi to all, Recently I discovered that my Acer Aspire One BIOS (0.3305) has an authentic SLIC table in the bios, even if there are no models on the market bundled with Vista. So I would try to perform a real OEM activation without using a SLIC emulator, or any other hack. I need the corresponding OEM certificate, which so far I did not found. The SLIC OEM ID is INTEL, the Table ID is Napa (checked with Everest 4.60). It should be full SLP 2.0 compliant (384 bytes long). I ripped the table and, if allowed, i could attach it on this thread on a future reply. If anyone can help please reply to this, this information may potentially be useful for a wide range of people, at least everyone who owns this netbook and wants to install Vista on it in the best possible way. Thanks in advance, See you soon.
