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.
DPMS is a hardware standard that allows graphics cards to communicate with DPMS-compliant monitors via a special signalling system that can be used with existing graphics controllers and monitor cables. This signalling system allows the graphics card to tell the monitor to go into a number of different power management or power saving states ...
BIOS POST card for ISA bus BIOS POST card for PCI bus Professional BIOS POST card for PCI bus Two POST seven-segment displays integrated on a computer motherboard. The original IBM BIOS made POST diagnostic information available by outputting a number to I/O port 0x80 (a screen display was not possible with some failure modes). Both progress ...
The userspace X.Org DDX driver for Intel graphics cards was also the first to use the new GEM and KMS APIs. [146] KMS support for the radeon DRM driver was added to Linux 2.6.31 release of September 2009. [147] [148] [149] The new radeon KMS driver used the TTM memory manager but exposed GEM-compatible interfaces and ioctls instead of TTM ones ...
The first PC video adapter card that had an option ROM was the IBM EGA, introduced in 1984 with the IBM PC AT. (The Hercules Graphics Card had no option ROM and no BIOS support except for its MDA-compatible features, for which it relied in the IBM-supplied MDA support in the main BIOS.)
For example, an IBM PC might have either a monochrome or a color display adapter (using different display memory addresses and hardware), but a single, standard, BIOS system call may be invoked to display a character at a specified position on the screen in text mode or graphics mode. The BIOS provides a small library of basic input/output ...
A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
The System tab displays the current DirectX version, the computer's hostname, the operating system's version, information on the system BIOS, and other data.The DirectX Files tab displays information about the versions of specific DirectX system files, which are portable executables or dynamic-link libraries (DLLs).
