Boot Animation
A bootsplash, also known as a bootscreen, is a graphical representation of the boot process of the operating system. A bootsplash can be a simple visualization of the scrolling boot messages in the console, but it can also present graphics or some combinations of both. Unlike splash screens, a bootsplash is not necessarily designed for marketing purposes; it can be intended to enhance the experience of the user as eye candy, or provide the user with messages (with an added advantage of color-coding facility) to diagnose the state of the system. Microsoft Windows All versions of Microsoft Windows feature a boot screen, which is loaded during the startup process. With extra, third-party utilities, it is possible to replace the default Windows boot screen with custom images, text, and/or animations. Windows Vista In Windows Vista, the default boot screen is represented by a green indeterminate progress indicator. The boot screen can be changed so that it displays a static im ...

BIOS
In computing, BIOS (, ; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). The BIOS firmware comes pre-installed on an IBM PC or IBM PC compatible's system board and exists in some UEFI-based systems to maintain compatibility with operating systems that do not support UEFI native operation. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS originally proprietary to the IBM PC has been reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a ''de facto'' standard. The BIOS in modern PCs initializes and tests the system hardware components ( Power-on self-test), and loads a boot loader from a mass storage device which then ...

Splash Screen
A splash screen is a graphical control element consisting of a window containing an image, a logo, and the current version of the software. A splash screen can appear while a game or program is launching. A splash page is an introduction page on a website. A splash screen may cover the entire screen or web page; or may simply be a rectangle near the center of the screen or page. The splash screens of operating systems and some applications that expect to be run in full screen usually cover the entire screen. Purpose Splash screens are typically used by particularly large applications to notify the user that the program is in the process of loading. They provide feedback that a lengthy process is underway. Occasionally, a progress bar within the splash screen indicates the loading progress. A splash screen disappears when the application's main window appears. Splash screens may be added for a period of time and then replaced anew. Splash screens typically serve to enhance the l ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with addition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Usplash
Usplash is a software project in the Ubuntu community. Historically, scrolling text "verbose mode" has typically appeared on Linux computers during boot. Usplash replaces the scrolling-text screens with a graphical splash screen. It was designed to replace Bootsplash, which did the same thing on the kernel space level. Since usplash operates in user space, it can be updated without recompiling the kernel. Usplash uses the Linux framebuffer interface or, alternatively, direct VESA access to display the splash screen. In Ubuntu 9.10 "Karmic Koala", Usplash is only used in the preliminary stages of booting, after which XSplash takes over. In Ubuntu 10.04 LTS "Lucid Lynx", Usplash has been fully replaced by Plymouth, which uses Direct Rendering Manager (DRM) and KMS driver. See also * Plymouth Plymouth () is a port city status in the United Kingdom, city and unitary authority in South West England. It is located on the south coast of Devon, approximately south-west of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KMS Driver
The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards. DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display. DRM was first developed as the kernel-space component of the X Server Direct Rendering Infrastructure, but since then it has been used by other graphic stack alternatives such as Wayland. User-space programs can use the DRM API to command the GPU to do hardware-accelerated 3D rendering and video decoding, as well as GPGPU computing. Overview The Linux kernel already had an API called fbdev, used to manage the framebuffer of a graphics adapter, but it couldn't be used to handle the needs of modern 3D-accelerated GPU-based video hardware. These devices usually require setting and managing a command queue in their own memory to dispatch commands to the GPU and also require man ...

Plymouth (software)
Plymouth is a free application which provide bootsplash for Linux, which handles user interaction during the boot process. Plymouth supports animations using Direct Rendering Manager (DRM) and the KMS driver and is bundled into initrd which enables it to be launched before the file system is mounted. The program is named after Plymouth Rock, a name which symbolizes the program's role as a first point of entry for users to interact with a computer system. ''Plymouth'' was first included in Fedora 10 "Cambridge" shipped on November 25, 2008 where it replaced Red Hat Graphical Boot (RHGB). Ubuntu includes it in the Ubuntu 10.04 LTS "Lucid Lynx" release shipped on April 29, 2010. Mandriva switched from Splashy to Plymouth with versioAdélie (2010.0) History The development of Plymouth began in May 2007 and began under the leadership of Ray Strode. However, there was little support for this project until early 2008, when the decision to introduce Plymouth into Fedora 10 gave a bo ...

Gentoo Linux
Gentoo Linux (pronounced ) is a Linux distribution built using the Portage package management system. Unlike a binary software distribution, the source code is compiled locally according to the user's preferences and is often optimized for the specific type of computer. Precompiled binaries are available for some larger packages or those with no available source code. Gentoo Linux was named after the gentoo penguin, the fastest swimming species of penguin. The name was chosen to reflect the potential speed improvements of machine-specific optimization, which is a major feature of Gentoo. Gentoo package management is designed to be modular, portable, easy to maintain, and flexible. Gentoo describes itself as a meta-distribution because of its adaptability, in that the majority of users have configurations and sets of installed programs which are unique to the system and the applications they use. History Gentoo Linux was initially created by Daniel Robbins as the ''Enoch Lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KNOPPIX Booting
KNOPPIX ( ) is an operating system based on Debian designed to be run directly from a CD / DVD (Live CD) or a USB flash drive (Live USB), one of the first live operating system distributions (just after Yggdrasil Linux). Knoppix was developed by, and named after, Linux consultant Klaus Knopper. When starting a program, it is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly. Although KNOPPIX is primarily designed to be used as a Live CD, it can also be installed on a hard disk like a typical operating system. Computers that support booting from USB devices can load KNOPPIX from a live USB flash drive or memory card. There are two main editions: the traditional compact-disc (700 megabytes) edition and the DVD (4.7 gigabytes) "Maxi" edition. The CD edition had not been updated since June 2013 until recently. As of version 9.1, CD images are being released once again. Each main edition has two language-specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
