device		mc146818	# Motorola MC146818 and compatible clocks

#
# Optional devices:
#

device		auxio		# auxiliary I/O device
device		creator		# Creator, Creator3D and Elite3D framebuffers
device		machfb		# ATI Mach64 framebuffers

device		ofw_console	# Open Firmware console device
option 		OFWCONS_POLL_HZ=4 # 20 or more works best on Ultra2

# PS/2 mouse
device		psm

# Options for psm:

# `flags' for atkbd:
#       0x01    Force detection of keyboard, else we always assume a keyboard
#       0x02    Don't reset keyboard, useful for some newer ThinkPads
