This is because CMOS may experience a failure mode known as a stuck-open fault, which cannot be reliably detected with one test vector and requires that two vectors be applied sequentially. The model also fails to detect bridging faults between adjacent signal lines, occurring in pins that drive bus connections and array structures.

After restarting, it shows a message for a few seconds informing the user that a problem caused the computer to restart, before continuing to boot. The message now includes a Chinese translation.

In the context of free and open-source software, proprietary software only available as a binary executable is referred to as a blob or binary blob.The term usually refers to a device driver module loaded into the kernel of an open-source operating system, and is sometimes also applied to code running outside the kernel, such as system firmware images, microcode updates, or userland programs.
An unlocked bootloader, showing additional available options. Bootloader unlocking is the process of disabling the bootloader security that makes secure boot possible. It can make advanced customizations possible, such as installing custom firmware.
INT 10h is fairly slow, so many programs bypass this BIOS routine and access the display hardware directly. Setting the video mode, which is done infrequently, can be accomplished by using the BIOS, while drawing graphics on the screen in a game needs to be done quickly, so direct access to video RAM is more appropriate than making a BIOS call ...
One way to track down the source of the problem for games is to run them in windowed-mode. Windows Vista has a feature that can help track down the cause of a CTD problem when it occurs on any program. [clarification needed] Windows XP included a similar feature as well. [clarification needed]
