iSCSI Boot Windows - Version 1.4 CCBoot, from www.ccboot.com, allows a diskless boot of either Windows XP, Windows 2003, Windows Vista, or Windows 2008 from an iSCSI target machine remotely located over a standard IP network. Diskless boot makes it possible for computers to be operated without a local disk. The 'diskless' computer is connected to a hard drive over a network and boots up an operating system from a remotely located machine. CCBoot is the convergence of the rapidly emerging iSCSI protocol with gPXE diskless boot technology.
