  2. Dual-ported video RAM - Wikipedia

    en.wikipedia.org/wiki/Dual-ported_video_RAM

    Dual-ported video RAM (VRAM) is a dual-ported variant of dynamic RAM (DRAM), which was once commonly used to store the framebuffer in graphics adapters. Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.

  3. Video BIOS - Wikipedia

    en.wikipedia.org/wiki/Video_BIOS

    Much the way the system BIOS provides a set of functions that are used by software programs to access the system hardware, the video BIOS provides a set of video-related functions that are used by programs to access the video hardware as well as storing vendor-specific settings such as card name, clock frequencies, VRAM types & voltages.

  4. GPU-Z - Wikipedia

    en.wikipedia.org/wiki/GPU-Z

    TechPowerUp GPU-Z (or just GPU-Z) is a lightweight utility designed to provide information about video cards and GPUs. [2] The program displays the specifications of Graphics Processing Unit (often shortened to GPU) and its memory; also displays temperature, core frequency, memory frequency, GPU load and fan speeds.

  5. Macintosh Quadra 950 - Wikipedia

    en.wikipedia.org/wiki/Macintosh_Quadra_950

    With a Macintosh Processor Upgrade Card installed, this computer is known as the Power Macintosh 950. In 1993, the 950 was overtaken in performance by the less expensive Quadra 800 and 840AV . The newer Quadras had the addition of interleaved RAM, as well as an enhanced video system and SCSI bus.

    If the installed display driver has passed Windows Hardware Quality Labs testing, DirectX Diagnostic Tool will display this result on the right side of the window. The Music tab displays information about the computer's MIDI settings, and lists different music-related software and hardware on your computer.

  7. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    Some computer designs have used non-button cell batteries, such as the cylindrical "1/2 AA" used in the Power Mac G4 as well as some older IBM PC compatibles, or a 3-cell nickel–cadmium (Ni–Cd) CMOS battery that looks like a "barrel" (common in Amiga and older IBM PC compatibles), which serves the same purpose. These motherboards often have ...

  8. VESA BIOS Extensions - Wikipedia

    en.wikipedia.org/wiki/VESA_BIOS_Extensions

    hwinfo is the hardware detection tool used in SuSE Linux and in some other Linux distributions. [10] Running hwinfo --framebuffer reports graphics information, including VESA modes on a "Mode" line. mdt is a Linux or DOS tool that uses VESA BIOS functions to read monitor data.

  9. Shared graphics memory - Wikipedia

    en.wikipedia.org/wiki/Shared_graphics_memory

    Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet the needs of the current program. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared "fast RAM" if it was available.
