It is free and open-source software, and is available in 32- and 64-bit variants. It is digitally signed, which makes it compatible with 64-bit versions of Microsoft Windows without having to be run in Test mode. The 64-bit version has no practical limit to the size of RAM disk that may be created.
Therefore, PCs running 64-bit versions of Windows Vista SP1, Windows Vista SP2, Windows 7, Windows Server 2008 and Windows Server 2008 R2 are compatible with UEFI Class 2. [ 128 ] [ 129 ] 32-bit UEFI was originally not supported since vendors did not have any interest in producing native 32-bit UEFI firmware because of the mainstream status of ...

Windows NT (and later Microsoft operating systems) uses the disk signature as an index to all the partitions on any disk ever connected to the computer under that OS; these signatures are kept in Windows Registry keys, primarily for storing the persistent mappings between disk partitions and drive letters. It may also be used in Windows NT BOOT ...
The first stage of PC boot loaders (FSBL, first-stage boot loader) located on fixed disks and removable drives must fit into the first 446 bytes of the master boot record in order to leave room for the default 64-byte partition table with four partition entries and the two-byte boot signature, which the BIOS requires for a proper boot loader ...
The Windows operating system uses this partition for compatibility purposes. No meaningful data is stored within the MSR. Rather, when compatibility needs arise, Windows shrinks this partition to make way for other special-purpose partitions, which may contain data. [1] The GPT label for this partition type is E3C9E316-0B5C-4DB8-817D ...
The Windows Disk Management MMC plugin can directly mount a VHD file as a drive letter in Windows 7/Server 2008 and newer. For situations where mounting a VHD within the operating system is undesirable, several programs enable software developers to inspect and modify VHD files, including .NET DiscUtils, WinImage, and R1soft Hyper-V VHD Explorer.
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
