#       $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.
