    in my case i have a Acer Travelmate 6592 Notebook. It can be orderd with Vista Home Premium, Business or XP. Let's think i have orderd the Home Premium Version and i'm going to update my Bios because of errors. But the actual BIOS (1.53) doesn't contain a SLIC table (even if you select you have Vista installed). Is this meaning, that if you have a preinstalled Vista, you can't update your Bios without loosing the activation?!

    This is the point every OEM has to manage.

    -Some update flash-tools check for what bios is already applied (check for Vista OEM licensed bios). Some OEM's have got another flash tool which is hidden for the public. So the public flash tool doesn't write ALL areas of bios or modifies the bios file during flash process.
    Some of these bioses have got a 'half mapped SLIC' already. The 'other part' is present at the Vista licensed machines only. (Applied by OEM at preinstall)

    -If you are a lucky one, even the bios of the Notebook that comes without Vista preinstalled contains a SLIC already!! Or you may flash a bios that contains a fully present SLIC from the manufacturer.

    The OEMS usually cannot afford a loss of SLIC of a customer who has got a valid OEM license of it......but in that case you may activate using COA sticker to get a COA_SLP license by activating via wire.

    Not unless your BIOS contains the WinXP OEM license code. If you already have Vista, I would suggest that getting and installing a copy of WinXP VLK would be much easier than modding your BIOS--although the automatic BIOS modders generate code for both Vista and XP these days.
