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