i am looking into PXE Boot to boot Linux from U-Boot

i am using a sollution thar resembles the PXELINUX sollution

i have one fundamental issue i dont understand about the process: the pxe client tries to get a pxe config file from a server. it looks for a file with a prefix that matches its IP, MAC or UUID. this mean the PXE server needs to keep a file for each client it wants to load (unless using default). this doesnt make sense to me. i would expect the client to get a the adress to the file based on its arch/capabilites and so on

is there a different way to specify the PXE boot cfg file ?

Thanks in advance

Answer 1

Specific PXE ROM implementations may send along a machine type string ("SUNW,Ultra-250", "SUNW,Sun-Fire-T1000") with the initial DHCP request, but I guess the consumer-class industry has not been bright enough to get there yet.

The PXE ROM only downloads that one file, and it is the so-downloaded program (probably pxelinux.0 in your case) that decides what other files to download — such as config files. In other words, if you have the source to pxelinux, you can edit it to do as you like and implement a config file finding mechanism that matches your requirements.
