Building undionly.kpxe

Build Requirements

You will need root access: (example:)

sudo su -

Enter the Password of the current user. OR

su -

Enter the Password for the root user.

Packages Needed

Redhat Based Linux

yum -y groupinstall "Development Tools"
yum -y install git wget

Debian Based Linux

apt-get install build-essential git wget

Get the Source

1. Open a terminal or console on your linux box.
2. Obtain root privileges (e.g. sudo su -,su - root)
3. Download the source to the home directory (e.g. /root or ~/)

   • git clone http://git.ipxe.org/ipxe.git

4. Change to the src directory

   • cd /root/ipxe/src

Create iPXE Script based on your needs.

NOTE: All paths assumed as /root/ipxe/src when editing files or creating the ipxescript. This is because you can only build the files from within the src folder of the ipxe source.

Default ipxe script (/tftpboot/default.ipxe)

• wget https://svn.code.sf.net/p/freeghost/code/trunk/src/ipxe/src/ipxescript

Custom ipxe script

• vi ipxescript

Make the file so it contains your "custom" code.

Example code base: (Embedding the default.ipxe script into undionly.)

NOTE: CHANGE x.x.x.x to the IP of your FOG Server

#!ipxe
dhcp || reboot
cpuid --ext 29 && set arch x86_64 || set arch i386
params
param mac ${net0/mac}
param arch ${arch}
chain http://x.x.x.x/fog/service/ipxe/boot.php##params

 * specified in tenths of a second for which the banner should appear.
 * A value of 0 disables the banner.
 *
 * ROM_BANNER_TIMEOUT controls the "Press Ctrl-B to configure iPXE"
 * banner displayed only by ROM builds of iPXE during POST.  This
 * defaults to being twice the length of BANNER_TIMEOUT, to allow for
 * BIOSes that switch video modes immediately before calling the
 * initialisation vector, thus rendering the banner almost invisible

Build the undionly/ipxe files.

I USE THE FOLLOWING COMMAND TO BUILD ALL FILES AT ONCE. Remove the {}'s and only apply the file you wish to build if you want only a specific file.

make bin/{undionly,ipxe}.{,k,kk}pxe EMBED=ipxescript

Copy and/or Use your files

I USE THE FOLLOWING COMMAND TO COPY ALL FILES AT ONCE. Remove the {}'s and only copy the file you wish to use if you want only a specific file.

cp bin/{undionly,ipxe}.{,k,kk}pxe /tftpboot/ 

Use other undionly or ipxe files

There are two ways you can accomplish this, the easiest is the first method: CHANGE <filename> with the filename you wish to try

• Copy the file you wish to use as undionly.kpxe

cd /tftpboot
mv undionly.kpxe undionly.kpxeTEST1; cp <filename> undionly.kpxe

You can also just make a symbolic link to the file you wish to use, though the first time you do this you will have to, at the very least, rename the "real" undionly.kpxe file to something else. To do the same but as a symbolic link use:

cd /tftpboot
mv undionly.kpxe undionly.kpxeREAL
ln -s <filename> undionly.kpxe

Don't forget to remove the link if you want to use other files.

Debugging

In some cases it's necessary to enable debugging output to be able to find errors. So follow the above steps to build iPXE and add the following parameter:

make bin/{undionly,ipxe}.{,k,kk}pxe EMBED=ipxescript DEBUG=undi,dhcp

This will enable debugging in the UNDI part of the source code. Other important parameters are efi_init, efi_snp, realtek, 3c5x9 or any other iPXE driver you need debugging for!
