7.7 Building PXELINUX

In this example, we use PXE to boot Linux with PXELINUX from the syslinux package.

This can be obtained from the following website:

http://www.kernel.org/pub/linux/utils/boot/syslinux/

To build PXELINUX, you will need nasm(1), an x86 assembler; which can be obtain from

the following website:

http://sourceforge.net/projects/nasm

You only need to build pxelinux.0. To build it:

# make pxelinux.0

Copy pxelinux.0 to your /tftpboot directory on your TFTP server. Next, copy your

ramdisk to /tftpboot:

# cp ${INITRD}/initrd.img.gz /tftpboot/

Copy your kernel to /tftpboot/ and copy the filesystem you want to use to

/tftpboot/.

Create a config file named "default" for PXE. It goes in the directory

/tftpboot/pxelinux.cfg/

Example:

KERNEL vmlinuz-2.4.20-6smp

APPEND nfsdir=10.40.0.1:/NFSroot/client1 init=/sbin/init \

initrd=initrd.img.gz

TIMEOUT 10

KERNEL specifies the kernel image

APPEND needs the IP address of the NFS server, the location of the filesystem, and the

location of the ramdisk we created for AMSO1100.

7.8 Diskless Linux Boot via PXE

There are several HOWTOs that explain booting a diskless node via PXE. Eg:
