Flashing [6] is a process that involves the overwriting of existing firmware or data, contained in EEPROM or flash memory module present in an electronic device, with new data. [6] This can be done to upgrade a device [ 7 ] or to change the provider of a service associated with the function of the device, such as changing from one mobile phone ...
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
As of 2014, new PC hardware predominantly ships with UEFI firmware. The architecture of the rootkit safeguard can also prevent the system from running the user's own software changes, which makes UEFI controversial as a legacy BIOS replacement in the open hardware community.
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.

Intel Active Management Technology (AMT) is hardware-based technology built into PCs with Intel vPro technology.AMT is designed to help sys-admins remotely manage PCs out-of-band when PC power is off, the operating system (OS) is unavailable (hung, crashed, corrupted, missing), software management agents are missing, or hardware (such as a hard disk drive or memory) has failed.
The SRM firmware (also called the SRM console) is the boot firmware written by Digital Equipment Corporation (DEC) for computer systems based on the DEC Alpha microprocessor. SRM are the initials of (Alpha) System Reference Manual , the publication detailing the Alpha AXP architecture and which specified various features of the SRM firmware.
Legacy systems are considered to be potentially problematic by some software engineers for several reasons. [4]If legacy software runs on only antiquated hardware, the cost of maintaining the system may eventually outweigh the cost of replacing both the software and hardware unless some form of emulation or backward compatibility allows the software to run on new hardware.
Common software upgrades include changing the version of an operating system, an office suite, of an anti-virus program, or of various other tools. Common firmware upgrades include the updating of the iPod control menus, the Xbox 360 dashboard, or the non-volatile flash memory that contains the embedded operating system for a consumer ...
