DHCP boot legacy and UEFI

Hi Team,

 I ran into the problem of organizing a boot in legacy and UEFI on one DHCP pool, understanding rfc4578, or rather how to registaer two boot files on one DHCP pool with an understanding of 0, 6, 9 labels to select either legasy or EFI boot.

 I try with this config:

 

ip dhcp pool LAN
network 192.168.1.0 255.255.255.0
bootfile smsboot\x64\BOOTIA32.EFI
next-server x.x.x.x 
domain-name dot.lan
option 42 ip x.x.x.x xxx.x.x.
option 150 ip x.x.x.x x.x.x.x 
dns-server x.x.x.x x.x.x.x 
default-router 192.168.1.1 
option 60 ascii
option 66 ascii http://voip.dot.lan:8088/asterisk/phoneprov
option 67 ascii smsboot\x64\pxelinux.com
lease 3

With this configuration, only what works in the 

bootfile smsboot\x64\BOOTIA32.EFI

do not work option 67 ascii smsboot\x64\pxelinux.com (legacy)

I would be grateful for advice on how to organize.
