Splashtop OS (previously known as SplashTop) is a discontinued proprietary Linux distribution intended to serve as instant-on environment for personal computers. The original concept of Splashtop was that it was intended to be integrated on a read-only device and shipped with the hardware, rather than installed by the user. It did not prevent the installation of another operating system for dual booting. It was an instant-on commercial Linux distribution targeting PC motherboard vendors and other device manufacturers. The first OEM partner for the original Splashtop was ASUS, and their first joint product was called Express Gate. Later, other computer manufacturers also built Splashtop into certain models and re-branded it under different names. The aspects below detailing these events are retained verbatim from past articles, for historical reference.
Support for Splashtop OS has been withdrawn and downloads of Splashtop OS have been disabled on the Splashtop website.
Splashtop OS (beta) version 0.9.8.1 uses Microsoft Bing as search engine, a Chromium-based web browser with Adobe Flash Player plug-in preinstalled. Existing Windows bookmarks and Wi-Fi settings can be imported from Windows.
Most versions of Asus motherboards no longer come with Splashtop preinstalled, as the manufacturer now limits the inclusion of its built-in Express Gate flash drive to "Premium" motherboards such as the P6T Deluxe and P7P55D-E Premium. Other Asus motherboards allow installation of the compact OS via a Windows-only based installer on its support CD. Installation from CD requires a Windows partition to store 500 MB of files, which has to be a SATA drive defined as IDE (no support for AHCI).[self-published source] If one doesn't have a Windows-based machine, it is possible to install Splashtop on a USB hard drive, from the sources.[self-published source]
As of June 2010, Splashtop, as supplied for Asus motherboards, had no support for add-on wireless hardware such as PCI cards.
Splashtop can work with a 512 MB flash memory embedded on the PC motherboard. The flash memory can be also emulated on the Windows C: drive (see below). A proprietary core engine starts at the BIOS boot and loads a specialized Linux distribution called a Virtual Appliance Environment (VAE). While running this VAE, the user can launch Virtual Appliances (VA). Skype is a VA, for instance.
The Sony VAIO versions such as 188.8.131.52 are installed as VAIO Quick Web Access. The installer and the resulting SquashFS files occupy roughly 2×250 MB. The SquashFS files consist of a hidden splash.idx and two hidden folders splash.sys and splash.000 in the Windows C:-partition, where splash.000 corresponds to splash.sys\persist for a DOS file system emulation of an USB flash drive.[self-published source] The MD5 checksums of the various Bootsplash bs-xxxx.sqx and Virtual Appliance va-xxxx.sqx files (including a special Firefox configuration) are noted in splash.sys\version for a simple integrity check at the Splashtop start. VAIO laptops offer special buttons ASSIST, WEB, or VAIO depending on the model. The power button on these laptops triggers an ordinary PC boot process, the WEB button starts Splashtop. If a Windows-version configured for VAIO is already running the WEB button only starts the default browser.
