Description Sevan Janiyan 2015-12-08 09:09:30 EST 
Document URL: 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/chap-installation-server-setup.html#sect-network-boot-setup-bios

Section Number and Name: 
21.1.1
Configuring a PXE Server for BIOS-based AMD64 and Intel 64 Clients
Describe the issue: 
In step 7, it's suggested to "Add a configuration file named default to the pxelinux/ directory"

This is incorrect as the client requests the file from pxelinux/pxelinux.cfg
Suggestions for improvement: 
"Add a configuration file named default to the pxelinux/pxelinux.cfg directory"

"A sample configuration file at /var/lib/tftpboot/pxelinux/pxelinux.cfg/default might look like:"

Additional information:

Found using CentOS 7 1503.
This behaviour can be confirmed using tcpdump on the boot server whilst a client attempts to PXE boot:

tcpdump: listening on em0, link-type EN10MB
