About

The Preboot Execution Environment (PXE, aka Pre-Execution Environment, or 'pixie') is an environment to boot computers using a network interface card independently of available data storage devices (like hard disks) or installed operating systems.
For a high-level overview of network booting, see Network booting.

PXE was introduced as part of the Wired for Management framework by Intel and is described in the specification (v2.1) published by Intel and Systemsoft on September 20, 1999. It makes use of several network protocols like IP, UDP, DHCP and TFTP and of concepts like GUID/UUID and Universal Network Device Interface and extends the firmware of the PXE client (the computer to be bootstrapped via PXE) with a set of predefined APIs.

Create turbocharged storage using tmpfs

Everyone knows that RAM is so much faster than a hard disk. To illustrate, while a modern SATA disk has peak transfer rates of 375 MB/s, modern RAM can do a mind blowing 12.500 MB/s! Normally only the system itself makes use of this ultra fast storage, but we can also access this space directly. And that opens a great window of opportunity.
