On the other side, some companies actively encourage modding of their products. In cases such as TiVo and Google, there has been an informal agreement between the modders and the company in which the modders agree not to do anything that destroys the company's business model and the company agrees to support the modding community by providing technical specifications and information.
ROM BIOS firmware on a Baby AT motherboard. In some respects, the various firmware components are as important as the operating system in a working computer. However, unlike most modern operating systems, firmware rarely has a well-evolved automatic mechanism of updating itself to fix any functionality issues detected after shipping the unit.
Later, 386-class computers started integrating the BIOS setup utility in the ROM itself, alongside the BIOS code; these computers usually boot into the BIOS setup utility if a certain key or key combination is pressed, otherwise the BIOS POST and boot process are executed. Award BIOS setup utility on a standard PC. A modern BIOS setup utility ...
On smartphones, tablets, and other devices, an over-the-air update is a firmware or operating system update that is downloaded by the device over the internet. Previously, users had to connect these devices to a computer over USB to perform an update. These updates may add features, patch security vulnerabilities, or fix software bugs.
Files and folders on the device may be copied to the PC, and the PC may copy files and folders to the device. Transfer performance of USB sideloading varies greatly, depending on the USB version supported, and further still by the actual engineering implementation of the USB controller.
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
A patch is data that is intended to be used to modify an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. [1] [2] A patch may be created to improve functionality, usability, or performance. A patch is typically provided by a vendor for updating the software that they provide.
The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting.
