See options(4) for more detail. 8 9 10# Options for variants of the Sun SPARC architecure. 11# We currently support three architecture types; at least one is required. 12options SUN4 # sun4/100, sun4/200, sun4/300 13options SUN4C # sun4c - SS1, 1+, 2, ELC, SLC, IPC, IPX, etc. 14options SUN4M # sun4m - SS10, SS20, Classic, etc. 15 16#options SUN4_MMU3L # 3-level MMU on sun4/400; (incomplete) 17 18## System options specific to the sparc machine type 19 20# Blink the power LED on some machines to indicate the system load. 21#options BLINK 22 23## Use a faster console than the PROM's slow drawing routines. Not needed 24## for headless (no framebuffer) machines. 25options RASTERCONSOLE # fast rasterop console 26 27 28#### System options that are the same for all ports 29 30## Root device configuration: change the ?'s if you are going to use a 31## nonstandard root partition (other than where the kernel is booted from) 32## and/or nonstandard root type (not ffs or nfs). Normally this can be 33## automagically determined at boot time. 34 35config netbsd root on ? type ? 36 37## Virtual memory configuration. There are two choices, the old Mach 38## based VM system, or the new UVM system. 39options OLDVM # MACH VM 40#options UVM # UVM VM 41 42## System call tracing (see ktrace(1)). 43options KTRACE 44 45## Collect statistics on kernel malloc's and free's.

Do not use this 103## option on a production machine. 104#options INSECURE 105 106## Allow non-root users to grab /dev/console with programs such as xconsole. 107## `xconsole' therefore does not need setuid root with this option enabled. 108#options UCONSOLE 109 110## `FDSCRIPTS' allows non-readable but executable scripts by providing a 111## pre-opened opaque file to the script interpreter. `SETUIDSCRIPTS', 112## which implies FDSCRIPTS, allows scripts to be set-user-id using the same 113## opaque file mechanism.
