  The device path protocol as defined in UEFI 2.0.\r
\r
  The device path represents a programatic path to a device. It's the view\r
  from a software point of view. It also must persist from boot to boot, so \r
  it can not contain things like PCI bus numbers that change from boot to boot.\r

8a7d75b0	2	The device path protocol as defined in UEFI 2.0.\r

d1f95000	4	The device path represents a programatic path to a device. It's the view\r
	5	from a software point of view. It also must persist from boot to boot, so \r
	6	it can not contain things like PCI bus numbers that change from boot to boot.\r
