UEFI applications can be developed and installed independently of the original equipment manufacturers (OEMs). A type of UEFI application is an OS boot loader such as GRUB, rEFInd, Gummiboot, and Windows Boot Manager, which loads some OS files into memory and executes them. Also, an OS boot loader can provide a user interface to allow the ...
A diagnostic program (also known as a test mode) is an automatic computer program sequence that determines the operational status within the software, hardware, or any combination thereof in a component, a system, or a network of systems. Diagnostic programs ideally provide the user with guidance regarding any issues or problems found during ...
Delays beginning the tests a fraction of a second to allow the hardware to stabilize. Jumps to ROM code in diagnostic card (if found) Disables and clears all DMA and interrupts. Turns on the screen. Checks the general hardware configuration. If the screen remains a light gray color and the tests continue, the hardware is OK.
Restore power, speed and stability with over 200 critical tests and 50 tools using the go-to solution for ultimate PC performance and trouble-free computing.
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
This eliminates the need for the operating system to probe hardware directly to discover what devices are present in the computer. The SMBIOS specification is produced by the Distributed Management Task Force (DMTF), a non-profit standards development organization. The DMTF estimates that two billion client and server systems implement SMBIOS.
UEFITool is a software program for reading and modifying EEPROM images with UEFI firmware. [1] It is written in C++ using the Qt library. [2] Features include the ability to view the flash regions and to extract and import them. [3] UEFITool allows the user to search for hex and text patterns. [4] UEFITool presents UEFI firmware images in a ...
The AMIDiag suite was introduced in 1991 and made available for MS-DOS, Microsoft Windows and UEFI platforms. [13] It includes both the Windows and DOS PC diagnostics programs. Later versions of AMIDiag support UEFI, which allows diagnostics to be performed directly on the hardware components, without having to use operating system drivers or ...
