Available for Windows 7 to 11, or Windows Server from 2008 R2 to 2022; 32/64-bit x86 or 64-bit ARM. SoftPerfect RAM Disk can access memory available to Windows, i.e. on 32-bit systems it is limited to the same 4 GB as the 32-bit Windows itself, otherwise for physical memory beyond 4 GB it must be installed on 64-bit Windows.
WDDM drivers allow video memory to be virtualized, [6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back.
Drivers that may be vulnerable include those for WiFi and Bluetooth, [19] [20] gaming/graphics drivers, [21] and drivers for printers. [ 22 ] There is a lack of effective kernel vulnerability detection tools, especially for closed-source OSes such as Microsoft Windows [ 23 ] where the source code of the device drivers is mostly proprietary and ...
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.
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, 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.
GDI was present in the initial release of Windows. MS-DOS programs had manipulated the graphics hardware using software interrupts (sometimes via the Video BIOS) and by manipulating video memory directly. Code written in this way expects that it is the only user of the video memory, which was not tenable on multi-tasked environment, such as ...
