#	$NetBSD: INSTALL_TINY,v 1.93 2005/08/19 02:03:52 christos Exp $
#
#	This kernel should be derived from INSTALL (which is derived
#	from GENERIC) with some features commented out.
#
#	This kernel has been optimized for space. It is targeted towards
#	small memory machines (4M). It has no SCSI, PCI or EISA. It does
#	have pcmcia, for old laptops.
