While experimenting for this answer, I came accross the following messages in NTLDR:

  • Windows could not start due to an error while booting from a RAMDISK.
  • The RAMDISK options specified in boot.ini are invalid.
  • Windows failed to build a bootable RAMDISK image.
  • Windows failed to open the RAMDISK image.

Does this mean that Windows XP includes a RAMDisk? Does anyone know how to use it?

Yes, it's a relic from the olden days.

Does anyone know how to use it?

You can use the dos based ramdrive.sys in Win XP by following these steps.

You can set ramdisk options for booting from WinPE. ntldr is used to boot a full Windows installation as well as WinPE 1.0 (used with XP) over PXE, so it includes this functionality. It is not something that is used during a standard boot-up of an already installed operating system
