  2. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings. It is traditionally called CMOS RAM because it uses a volatile , low-power complementary metal–oxide–semiconductor (CMOS) SRAM (such as the Motorola MC146818 [ 1 ] or similar) powered by a small battery when system and standby power is ...

  3. BIOS color attributes - Wikipedia

    en.wikipedia.org/wiki/BIOS_color_attributes

    A BIOS Color Attribute is an 8 bit value where the low 4 bits represent the character color and the high 4 bits represent the background color. The name comes from the fact that these colors are used in BIOS interrupts, specifically INT 10h, the video interrupt. When writing text to the screen, a BIOS color attribute is used to designate the ...

  5. Southbridge (computing) - Wikipedia

    en.wikipedia.org/wiki/Southbridge_(computing)

    The southbridge typically implements the slower capabilities of the motherboard in a northbridge-southbridge chipset computer architecture. In systems with Intel chipsets, the southbridge has been named I/O Controller Hub (ICH) and later replaced by Platform Controller Hub chipsets. In older Intel/AMD architectures the southbridge is usually ...

  6. Reset vector - Wikipedia

    en.wikipedia.org/wiki/Reset_vector

    In computing, the reset vector is the default location a central processing unit will go to find the first instruction it will execute after a reset. The reset vector is a pointer or address , where the CPU should always begin as soon as it is able to execute instructions.

  7. UEFI - Wikipedia

    en.wikipedia.org/wiki/UEFI

    UEFI replaces the BIOS that was present in the boot ROM of all personal computers that are IBM PC compatible, [5] [6] although it can provide backwards compatibility with the BIOS using CSM booting. Unlike its predecessor, BIOS, which is a de facto standard originally created by IBM as proprietary software, UEFI is an open standard maintained ...

  8. Video BIOS - Wikipedia

    en.wikipedia.org/wiki/Video_BIOS

    Video BIOS is the BIOS of a graphics card in a (usually IBM PC-derived) computer. It initializes the graphics card at the computer's boot time. It also implements INT 10h interrupt and VESA BIOS Extensions (VBE) [ 1 ] [ 2 ] for basic text and videomode output before a specific video driver is loaded.
