@lperoma said in Chainloading failed, hit 's' for the iPXE shell:
192.168.3.253
What device is that (manufacturer and model)? is that a soho router?
How does dnsmasq fit into this design? Is it setup as a proxy dhcp server?
The reason why I ask is I’ve seen many soho routers say (tell client computers) they are the boot server even if you have dhcp option 66 set correctly. The bios on the target computer is getting ipxe loaded correctly. Once iPXE starts it issues a dhcp discovery request again to find the boot server’s IP address. What it is getting this time is your gateway’s address.
With this new information I don’t think its spanning tree.
