I have a Raspberry Pi 4B running bookworm successfully network booting from a PC running Debian 12.
My question is about the PXE_OPTION43 in the bootloader configuration. In the documentation it states that this option "Overrides the PXE Option43 match string with a different string. " and that the default is "Raspberry Pi Boot".
This implies that I should be able to change this string to something other than the default but it doesn't seem to work.
My working dnsmasq config has a line that looks like this:The default bootloader config does not have the PXE_OPTION43 entry and network boot works fine with this config.
However, by editing bootloader config, and confirming with vcgencmd bootloader_configand changing the string in dnsmasq:
Network boot no longer works.
In wireshark I see the RPi send DHCP discover
and I see dnsmasq respond with DHCP offer, and that the option 43 string has indeed changed to "Different Boot" but that's all - it stops here.
The RPi won't boot until I change the dnsmasq pxe-service string back to "Raspberry Pi Boot" so it feels like the default string in the bootloader is not being overridden.
What am I doing wrong here please?
