===== Notes =====

The chip type is also displayed as part of the output from the ''[[:cmd:ifstat]]'' command.

The chip type is a descriptive name used internally by iPXE drivers, and should not be relied upon to remain stable between iPXE releases.  You should use it only to display information to a user.  For a more stable description which could be used systematically (e.g. to determine kernel modules corresponding to a network interface), you should use the ''[[:cfg:busid]]'' setting, or extract information directly from PCI configuration space.  For example:

  echo Downloading kernel module for ${net0/chip}...
  set vendor_id ${pci/${net0/busloc}.0.2}
  set device_id ${pci/${net0/busloc}.2.2}
  initrd http://my.web.server/kmod.php?v=${vendor_id}&d=${device_id} /lib/modules/${chip}.ko
