Can I send information to PXELINUX via special options in the DHCP response?

PXELINUX (starting with version 1.62) supports the following nonstandard DHCP options, which depending on your DHCP server you may be able to use to customize the specific behaviour of PXELINUX: • Option 208: pxelinux.magic must be set to F1:00:74:7E (241.0.116.126) for PXELINUX to recognize any special DHCP options whatsoever. • Option 209: pxelinux.configfile specifies the PXELINUX configuration file name. • Option 210: pxelinux.pathprefix specifies the PXELINUX common path prefix, instead of deriving it from the boot file name. This almost certainly needs to end in whatever character the TFTP server OS uses as a pathname separator, e.g. slash (/) for Unix. • Option 211: pxelinux.reboottime specifies, in seconds, the time to wait before reboot in the event of TFTP failure.
