In this example, driver_update.iso
is a driver update image file that you downloaded from the Internet to a directory on your PXE server. The target that you want to PXE boot from is located in /tftpboot/pxelinux/r6c/
At the command line, change to the directory that holds the file and enter the following commands:
$ cp driver_update.iso /tmp/initrd_update/dd.img
$ cd /tmp/initrd_update
$ find . | cpio --quiet -c -o | gzip -9 >/tmp/initrd_update.img
$ cp /tmp/initrd_update.img /tftpboot/pxelinux/r6c/dd.img
Edit the /tftpboot/pxelinux/pxelinux.cfg/default
file and include the following entry:
label r6c-dd
kernel r6c/vmlinuz
append initrd=r6c/initrd.img,r6c/dd.img
