Rarely an experienced user would reinstall Windows. In the case of the former, the boot loader will most likely inform the user the name of the missing file, allowing for the user to supply and/or reinstall the missing files to resolve the boot problem. In the case of the latter, however, the computer will not be able to boot, even into safe mode.
In later computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard. This allows easy, end-user updates to the BIOS firmware so new features can be added or bugs can be fixed, but it also creates a possibility for the computer to become infected with BIOS rootkits.
Bricking a device is most often a result of interrupting an attempt to update the device. Many devices have an update procedure which must not be interrupted before completion; if interrupted by a power failure, user intervention, or any other reason, the existing firmware may be partially overwritten and unusable.
In computing, the System Management BIOS (SMBIOS) specification defines data structures (and access methods) that can be used to read management information produced by the BIOS of a computer. [1] This eliminates the need for the operating system to probe hardware directly to discover what devices are present in the computer.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
In November 2007, HP released a BIOS update covering a wide range of laptops with the intent to speed up the computer fan and have it run constantly while the computer was on or off [154] to prevent the overheating of defective Nvidia graphics processing units (GPUs) that had been shipped to many of the original equipment manufacturers ...
First introduced in July 2006, [1] the HP Pavilion dv9000 series was a series of high-definition capable widescreen laptops using the HP Imprint finish. It featured 17.0" 16:10 LCD displays housed in a clamshell-type case, measured 15.16 x 11.65 x 1.57 inches, and weighs anywhere from about 7.7 lb (3.5 kg) to 8.4 lb (3.8 kg).
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.
