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.
Furthermore, on a modern x86 system, BIOS calls can only be performed in Real mode, or Virtual 8086 mode. v8086 is not an option in Long mode. This means that a modern operating system, which operates in Protected mode (32 bit), or Long mode (64 bit), would need to switch into real mode and back to call the BIOS - a hugely expensive operation.
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 ...
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). [1]
The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting. [8]
The different base addresses for color vs. monochrome modes makes it possible for an EGA to be used simultaneously with a monochrome graphics card in the same computer, or for an EGA in MDA text mode to be used simultaneously with a CGA in the same computer. EGA's native graphics modes are planar, as opposed to the interleaved CGA and Hercules ...
Coinciding with the release, VMware implemented support for TPM 2.0 and OpenGL 4.3, along with improvements to VMware Tools on Windows 11. [11] VMware Fusion 13 retains support for Intel Macs, distributing the software as a universal binary. [12] On May 13, 2024, it was announced that VMware Fusion Pro would become free for personal use.
However, the Scitech Nucleus Graphics engine lived on as SciTech SNAP (System Neutral Access Protocol) Graphics, SciTech SNAP DDC, and SciTech VBE Test Suite 8.0. [2] Unlike UniVBE, SciTech SNAP Graphics is designed as fully-accelerated binary-compatible graphic device driver, rather than patching a GPU BIOS to be VESA-compliant.
