Thank you for the insight. Let me look at those items a little further.

Also, This same Lenovo model alternatively comes with a Realtek Nic which Pxe boots just fine.

The IP address for TFTP is to our CentOS7 server running FOG, DHCP is handled by the Cisco Switch. There are no hops in between it and the switch.

I have an older model Lenovo desktop with a Marvel Yukon Nic
It is showing Yukon PXE v6.62.1.3 Pre Boot v2.1

During the PXE boot it is giving an error:
PXE-T01: File not Found
PXE-E3B: TFTP Error - File Not Found

The best lead I have found is that a tcpdump shows the tftp file name with garbage

the dump shows
tftp: [udp sum ok] 31 RRQ “undionly.kpxeM-^?” octet size 0

for many other models and brands of laptops that work just fine that same dump shows
tftp: [udp sum ok] 31 RRQ “undionly.kpxe” octet size 0

Is there some manipulation that can be done to the DHCP helper (options 66 & 67) or anything in tftp settings that might help that brand/version of Nic properly connect?
