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. [1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
At a minimum, if the CPU, BIOS, and the I/O interface upon which the POST card relies on are all working, a POST card can be used to monitor the system's Power-On Self Test (POST), or to diagnose problems with it.
Key Code Qualifier is an error-code returned by a SCSI device. ... power-on or self-test failure x: 4C: 00: LUN failed self-configuration x: 5C: 00: RPL status change ...
The BIOS in older PCs initializes and tests the system hardware components (power-on self-test or POST for short), and loads a boot loader from a mass storage device which then initializes a kernel. In the era of DOS , the BIOS provided BIOS interrupt calls for the keyboard, display, storage, and other input/output (I/O) devices that ...
This program runs a power-on self-test (POST) to check and initialize required devices such as main memory , the PCI bus and the PCI devices (including running embedded Option ROMs). One of the most involved steps is setting up DRAM over SPD, further complicated by the fact that at this point memory is very limited.
Self was tossed by the refs after picking up two technical fouls with 5 minutes, 49 seconds remaining in KU’s 79-50 loss to Texas Tech on Feb. 12 at United Supermarkets Arena in Lubbock, Texas ...
FPGAs, and PLAs allow POST (and BIOS) to exist as hardware. Before either one existed state machines existed in hardware. Most implemented a power-on self test -- imagine trying to debug one of these things without knowing if the machine was able to provide reliable debug information.
