Typical POST screen (AMI BIOS) Typical UEFI-compliant BIOS POST screen (Phoenix Technologies BIOS) Summary screen after POST and before booting an operating system (AMI BIOS) A power-on self-test ( POST ) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on.
Macs made from 1984 to 1998 used Old World ROM as the boot loader for all Macs produced around that time period. From 1998 up until the PowerPC to Intel transition, New World ROM was used for all Macs starting with the first iMac and later expanding to the first iBook and the Blue and White Power Mac G3.
Machine checks are a hardware problem, not a software problem. They are often the result of overclocking or overheating. In some cases, the CPU will shut itself off once passing a thermal limit to avoid permanent damage.
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 ...
When a system on a chip (SoC) enters suspend to RAM mode, in many cases, the processor is completely off while the RAM is put in self refresh mode. At resume, the boot ROM is executed again and many boot ROMs are able to detect that the SoC was in suspend to RAM and can resume by jumping directly to the kernel which then takes care of powering on again the peripherals which were off and ...

When debugging a concurrent and distributed system of systems, a bootloop (also written boot loop or boot-loop) is a diagnostic condition of an erroneous state that occurs on computing devices; when those devices repeatedly fail to complete the booting process and restart before a boot sequence is finished, a restart might prevent a user from ...
The corresponding system routine in Windows 9x, named SHELL_SYSMODAL_Message, does not halt the system like bug checks do. Instead, it displays the infamous "blue screen of death" (BSoD) and allows the user to attempt to continue. The Windows DDK and the WinDbg documentation both have reference information about most bug checks. The WinDbg ...
