1#	$NetBSD: INSTALL_TINY,v 1.135 2012/06/05 08:44:13 abs Exp $
2#
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.
