<h2 class="c6">About EtherBoot</h2>
|
|
|
|
<p class="c7">Etherboot is a software package for creating ROM
|
|
images that can download code over an Ethernet network to be
|
|
executed on an x86 computer. Many network adapters have a socket
|
|
where a ROM chip can be installed. Etherboot is code that can be
|
|
put in such a ROM. Etherboot is normally used for for booting PCs
|
|
diskless. This is useful in various situations, for example:</p>
|
|
|
|
<ul class="c11">
|
|
<li>An X-terminal.</li>
|
|
|
|
<li>Clusters of compute servers.</li>
|
|
|
|
<li>Routers.</li>
|
|
|
|
<li>Various kinds of remote servers, e.g. a tape drive server that
|
|
can be accessed with the RMT protocol.</li>
|
|
|
|
<li>Machines doing tasks in environments unfriendly to disks.</li>
|
|
|
|
<li>A user platform where remote partitions are mounted over the
|
|
network and you are willing to accept the lower speed compared to
|
|
disk.</li>
|
|
|
|
<li>Maintaining software for a cluster of equally configured
|
|
workstations centrally.</li>
|
|
</ul>
|
|
|
|
<p class="c7">Etherboot can boot computers faster than from a disk
|
|
because there are no delays in spinning up disks, etc. A moment's
|
|
calculation will show that even with a 10Mbit Ethernet, sending a
|
|
500kB kernel will take only a couple of seconds typically. With
|
|
100Mbit Ethernet it gets even better.</p>
|
|
|
|
<p class="c7">Compared to booting from solid-state devices, e.g.
|
|
Flash disks, Etherboot has the advantage of centralising software
|
|
adminstration, the tradeoff being the dependence on a server. This
|
|
can be partly alleviated by providing redundant servers.</p>
|
|
|
|
<p class="c7">Etherboot can work with RAM disks, NFS filesystems,
|
|
or even local disks, if desired. It's a component technology and
|
|
can be combined with other technologies to do things the way you
|
|
want.</p>
|
|
|
|
<p class="c7">Etherboot is usually used to load Linux, FreeBSD or
|
|
DOS. However the protocol and boot file formats are general, so
|
|
there is no reason why it could not be used to load arbitrary
|
|
images to a PC, including other OSes.</p>
|
|
|
|
<p class="c7">Etherboot is Open Source under the GNU General Public
|
|
License Version 2 (GPL2).</p>
|
|
|
|
<p class="c7">The components needed by Etherboot are</p>
|
|
|
|
<ul class="c11">
|
|
<li>A bootstrap loader, usually in an EPROM on a network card, or
|
|
installed in the flash BIOS, but could be put anywhere in the
|
|
address space the BIOS probes in. For testing this could be put on
|
|
a floppy disk or a hard disk partition. Some configurations may
|
|
even be always run from a floppy disk (e.g. temporary testing
|
|
setups or pedagogic uses).</li>
|
|
|
|
<li>A DHCP or bootp server, for returning an IP address and other
|
|
information when sent a MAC (Ethernet card) address.</li>
|
|
|
|
<li>A tftp server, for sending the kernel images and other files
|
|
required in the boot process. Alternatively, Etherboot can boot
|
|
from an NFS mount.</li>
|
|
|
|
<li>A Linux or FreeBSD kernel.</li>
|
|
|
|
<li>Optionally, a NFS server, for providing the disk partitions
|
|
that will be mounted if Linux or FreeBSD is being booted.</li>
|
|
|
|
<li>Optionally, a RAM disk contained in the loaded image. This can
|
|
be the initial RAM disk if desired.</li>
|
|
|
|
<li>Software tools for building the download image, and tools for
|
|
debugging.</li>
|
|
</ul>
