      3 #	This kernel should be derived from INSTALL (which is derived
      4 #	from GENERIC) with some features commented out.
      5 #
      6 #	This kernel has been optimized for space. It is targeted towards
      7 #	small memory machines (4M). It has no SCSI, PCI or EISA. It does
      8 #	have pcmcia, for old laptops.
