-and a file "boot.php" ​containing+You must choose between being able to load vesamenu.c32 directly ​and loading the current version of vesamenu.c32. 
 +==== vesamenu.c32 current ==== 
 +The current version of vesamenu.c32 can not be loaded directly from gPXE and requires PXELINUX as an intermediate layer. ​ You will need two PHP files, ​a boot.php containing
  
-    ​<?php +  ​<?php 
-     +   
-    header ( "​Content-type:​ text/​plain"​ ); +  header ( "​Content-type:​ text/​plain"​ ); 
-     +  echo "#​!gpxe\n";​ 
-    echo "#​!gpxe\n";​ +   
-    echo "​imgfree\n";​ +  $proto = "​https";​ 
-    echo "​login\n";​ +  // Comment out/remove the following if strictly using HTTPS 
-    echo "chain ". +  if (!isset($_SERVER["​HTTPS"​])) 
-          "https://​\${username:​uristring}:​\${password:​uristring}@"​. +    ​$proto = "​http";​ 
-          $_SERVER["​SERVER_NAME"​]. +   
-          dirname ( $_SERVER["REQUEST_URI"] ). +  // This assigns the host that gPXE should use using the most logical variables 
-          "/vesamenu.c32 menu.php\n"; +  if ( $_SERVER["​HTTP_HOST"​] != ""​ ) { 
-    ?>+    ​$host=$_SERVER["​HTTP_HOST"​];​ 
 +  } else { 
 +    if ( $_SERVER["​SERVER_NAME"​] != 0) { 
 +  $host=$_SERVER["​SERVER_NAME"​];​ 
 +    } else { 
 +  $host=$_SERVER["​SERVER_ADDR"​];​ 
 +    } 
 +  } 
 +   
 +  // Comment out/remove the following if you are running on a standard port 
 +  if (!((! isset($_SERVER["​HTTPS"​]) ) && ($_SERVER["​SERVER_PORT"​] == 80)) 
 +    && !(isset($_SERVER["​HTTPS"​]) && ($_SERVER["​SERVER_PORT"​] == 443)) ){ 
 +      if (strrpos($host,​ ":"​) == FALSE) 
 +        $host=$host.":"​.$_SERVER["​SERVER_PORT"​];​ 
 +  } 
 +   
 +  $uri=$_SERVER["​REQUEST_URI"​];​ 
 +  $dir=substr ( $uri, 0, strrpos ($uri, "/"​) + 1); 
 +   
 +  ​echo "#​!gpxe\n";​ 
 +  echo "​imgfree\n";​ 
 +  echo "​login\n";​ 
 +  echo "set 209:string bootcfg.php\n";​ 
 +  echo "set 210:​string ​". 
 +       $proto."://​\${username:​uristring}:​\${password:​uristring}@"​. 
 +       ​$host.$dir."\n"; 
 +  ​echo ​"chain \${210:​string}pxelinux.0\n"; 
 +  ?>
  
 +and a bootcfg.php containing
 +
 +  <?php
 +  ​
 +  header ( "​Content-type:​ text/​plain"​ );
 +  ​
 +  echo "UI runmenu\n\n";​
 +  echo "LABEL runmenu\n";​
 +  echo "COM32 vesamenu.c32\n";​
 +  echo "​APPEND menu.php\n";​
 +  ?>
 +
 +Selecting this method will require that you use gpxecmd.c32 to execute gPXE commands and scripts.
 +==== vesamenu.c32 directly ====
 +You will need a file "​boot.php"​ containing
 +
 +  <?php
 +  ​
 +  header ( "​Content-type:​ text/​plain"​ );
 +  ​
 +  $uri=$_SERVER["​REQUEST_URI"​];​
 +  $dir=substr ( $uri, 0, strrpos ($uri, "/"​) + 1);
 +  ​
 +  echo "#​!gpxe\n";​
 +  echo "​imgfree\n";​
 +  echo "​login\n";​
 +  echo "chain ".
 +       "​https://​\${username:​uristring}:​\${password:​uristring}@"​.
 +       ​$_SERVER["​HTTP_HOST"​].$dir.
 +       "​vesamenu.c32 menu.php\n";​
 +  ?>
 +
 +In order to use vesamenu.c32 directly from gPXE, you must use Syslinux-3.86 from [[http://​www.kernel.org/​pub/​linux/​utils/​boot/​syslinux/​3.xx/​]] and not the latest version.
