#	$NetBSD: GENERIC_PS2TINY,v 1.82 2024/01/29 18:27:13 christos Exp $
#
#	GENERIC-style kernel config for IBM PS/2 with MCA bus. It only contains
#	IBM PS/2 related stuff and has been generally trimmed down somewhat,
#	so that the kernel is small enough to be usable for 4MB machines. This
#	configuration is also used for INSTALL_PS2 kernels.
#
#	BEWARE:
#	 MCA support in NetBSD is still experimental at this
#	 stage and should be used with caution.
