Diskless System (Windows Embedded Standard 2009)
A diskless system is a device that contains no physical, rotating hard disk drive media, for example, hard disk emulator technology that uses nonvolatile memory. However, a diskless system might contain a removable storage device other than a hard disk, such as a floppy disk drive or a CD-ROM drive.
A diskless system can boot from the following file system sources:
A storage device that does not have physically rotating media, but instead uses flash memory or battery-backed RAM.
A bootable CD-ROM that uses the Windows Embedded Standard Enhanced Write Filter (EWF).
A file system that is accessible through a network connection, for example, a system that boots from a file system in a remote location.
The hardware configuration, writable storage capacity, and speed of the storage device are used to determine whether a diskless system can accommodate a pagefile. For information about the paging file, see Configuring the System Pagefile of a Run-Time Image.
