The FOG Project (named after Free and Open-source Ghost), is a suite of software tools for deploying disk images of Microsoft Windows and Linux using the Preboot Execution Environment (PXE). It makes use of TFTP , the Apache webserver and iPXE .
By default, read requests have an expiration time of 500ms, and write requests expire in 5 seconds. A rough version of the scheduler was published on the Linux Kernel Mailing List by Axboe in January 2002. [2] Measurements have shown that the deadline I/O scheduler outperforms the CFQ I/O scheduler for certain multi-threaded workloads. [3]
GHOST could clone a disk or partition to another disk or partition or to an image file. GHOST allows for writing a clone or image to a second disk in the same machine, another machine linked by a parallel or network cable, a network drive, or to a tape drive. 3.1 uses 286 with XMS and could still run on OS/2.

DRBL excels in two main categories. Disk Cloning. Clonezilla (packaged with DRBL) uses Partimage to avoid copying free space, and gzip to compress Hard Disk images. The stored image can then be restored to multiple machines simultaneously using multicast packets, thus greatly reducing the time it takes to image large numbers of computers.
Non-Macintosh systems, notably Windows and Linux, may not be typically booted in EFI mode and thus USB booting may be limited to supported hardware and software combinations that can easily be booted via EFI. [8] However, programs like Mac Linux USB Loader can alleviate the difficulties of the task of booting a Linux-live USB on a Mac.
At boot time, a workstation that has been set to boot from PXE will issue a BOOTP request via the network. Once the request is received, the DHCP Server will supply an IP address to the machine, and the DNS server will point the client computer to the RIS server, which in turn will issue a disc boot image (often called the "OS Chooser").
SDI usually contains either Disk BLOB (HD cloning or temporary SDI) or three other of them (bootable SDI). Windows Vista or Windows PE 2.0 boot sequence includes a boot.sdi file, which contains Part BLOB for an empty NTFS volume and a Table-of-Contents slot for the WIM image, which is stored on a separate on-disk file.
Darik's Boot and Nuke, also known as DBAN / ˈ d iː b æ n /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable , which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ...
