<h2 id="_description">DESCRIPTION</h2>
|
|
<div class="sectionbody">
|
|
<div class="paragraph"><p><strong>PXELINUX</strong> is a Syslinux derivative, for booting Linux off a network
|
|
server, using a network ROM conforming to the Intel PXE (Pre-Execution
|
|
Environment) specification. <strong>PXELINUX</strong> is <em>*not*</em> a program that is
|
|
intended to be flashed or burned into a PROM on the network card; if
|
|
you want that, check out Etherboot (<a href="http://www.etherboot.org/">http://www.etherboot.org/</a>).
|
|
Etherboot 5.4 or later can also be used to create a PXE-compliant boot
|
|
PROM for many network cards.</p></div>
|
|
<div class="paragraph"><p>PXELINUX generally requires that full file pathnames are 127 characters or shorter in length.</p></div>

<h2 id="_current_directory">CURRENT DIRECTORY</h2>
|
|
<div class="sectionbody">
|
|
<div class="paragraph"><p>The initial current working directory is either as supplied by DHCP
|
|
option 210 (pxelinux.pathprefix), the hardcoded path-prefix or the
|
|
parent directory of the PXELINUX file, as indicated by DHCP fields
|
|
<em>sname</em> and <em>file</em> (sname="192.168.2.3" and file="boot/pxelinux.0"
|
|
results in "tftp://192.168.2.3/boot/", "192.168.2.3::boot/" in older
|
|
PXELINUX format) with precedence specified under <strong>OPTIONS</strong>.</p></div>

<div class="sectionbody">

|
<div class="paragraph"><p>See <strong>syslinux.cfg</strong>(5) for the format of the contents.</p></div>
|
|
<div class="paragraph"><p>Because more than one system may be booted from the same server, the
|
|
configuration file name depends on the IP address of the booting
|
|
machine. After attempting the file as specified in the DHCP or
|
|
hardcoded options, PXELINUX will probe the following paths, prefixed
|
|
with "pxelinux.cfg/", under the initial current working directory:</p></div>
|
|
<div class="ulist"><ul>
|
|
<li>
|
|
<p>
|
|
The client UUID if provided by the PXE stack (note, some BIOSes don’t
|
|
have a valid UUID, and you might end up with something like all 1’s.)
|
|
This is in the standard UUID format using lower case hexadecimal digits,
|
|
e.g. b8945908-d6a6-41a9-611d-74a6ab80b83d.
|
|
</p>
|
|
</li>
|
|
<li>
|
|
<p>
|
|
The hardware type (using its ARP type code) and address, all in lower
|
|
case hexadecimal with dash separators; for example, for an Ethernet (ARP
|
|
type 1) with address 88:99:AA:BB:CC:DD it would search for the filename
|
|
01-88-99-aa-bb-cc-dd.
|
|
</p>
|
|
</li>
|
|
<li>
|
|
<p>
|
|
The client’s IPv4 address in upper-case hexidecimal (ie 192.168.2.91
|
|
→ C0A8025B; you can use the included progam "gethostip" to compute the
|
|
hexadecimal IP address for any host.) followed by removing characters,
|
|
one at a time, from the end.

<div class="paragraph"><p>Starting in release 3.20, if PXELINUX can not find a configuration file,

We should probably call the UDP receive function in the keyboard
