 Often, the file that the TFTP client will look for is  
 <replaceable>client-ip-in-hexclient-architecture</replaceable>.  To  
 compute <replaceable>client-ip-in-hex</replaceable>, take each byte of  
 the client IP address and translate it into hexadecimal notation.  If  
 you have a machine handy with the <command>bc</command> program, you  
 can use the program.  First issue the <userinput>obase=16</userinput>  
 command to set the output to hex, then enter the individual components  
 of the client IP one at a time.  As for  
 <replaceable>client-architecture</replaceable>, try out some values.  
   
 </para><para arch="i386">  
   
 For PXE booting, you can use the boot loader included with  
 <classname>syslinux</classname>: <filename>pxelinux.0</filename>. The boot  
 loader should be copied into the <filename>/tftpboot</filename>  
 folder. Then create a subdirectory within  
 <filename>/tftpboot</filename> named  
 <filename>/tftpboot/pxelinux.cfg</filename>, and within that directory  
 create a text file <filename>default</filename>. Here is an example of  
 a <filename>default</filename> file's contents:  
   
 <informalexample><screen>  
   
 default lanlinux  
 prompt 1  
   
 label lanlinux  
   kernel vmlinuz  
   append initrd=initrd.gz devfs=mount root=/dev/ram  
   
 </screen></informalexample>  
   
 Note that <userinput>devfs=mount</userinput> is important, because without it  
 there may be problems mounting the initrd.gz file system once the  
 kernel is booted. Also note that you may need an additional parameter  
 <userinput>ramdisk_size=<replaceable>size in KB</replaceable></userinput>,  
 depending on the image you are booting.

170  <filename>initrd.gz</filename> files (for the netboot installation method)  <filename>netboot/pxeboot.tar.gz</filename> tarball. Simply extract this
171  from the Debian ftp archive into the <filename>/tftpboot</filename> folder,  tarball into the <command>tftpd</command> boot image directory.
