# SUN350 machine description file
#
# This will work on a Sun 3/50. Problem is to keep the kernel small
# enough to fit in the first MB of RAM and not disrupt video memory.

# Standard information for Sun3 machines.
machine	sun3 m68k

# Machine type to be supported by this kernel.  Note:
# The SUN3 and SUN3X options are mutually exclusive!
# (Your kernel will only run on one or the other.)
makeoptions	MACHTYPE=sun3
options 	_SUN3_
options 	M68020

# The root node (required)
mainbus0 at root

# Standard defines
options 	EXEC_ELF32, EXEC_SCRIPT

makeoptions	COPTS="-Os"	# Optimise for space. Implies -O2

options 	FPU_EMULATE

# Needs to be set per system.  i.e change these as you see fit

# Standard system options
options 	SYSVMSG		# System V message queues
options 	SYSVSEM		# System V semaphores
options 	SYSVSHM		# System V shared memory
