>Description:
I built the mac68k NetBSD port from source (version 7.99.71) using the git repository: https://github.com/jsonn/src.git
When I tried to boot from the BSD/mac68k booter, it crashed. Here's a screenshot of the emulator, moments before it crashed: https://drive.google.com/open?id=0B1M0oDUwRDEidkZKVkRod2ZxUFE

Here's the terminal output (from which I launched Basilisk II):

>How-To-Repeat:
To repeat it, please install Basillisk II. Here's a link to the official site: https://basilisk.cebix.net/
Here are the instructions:

$ git clone https://github.com/cebix/macemu.git
After downloading and setting up the repository you can, for example, try to compile the Unix version of Basilisk II:

$ cd macemu/BasiliskII/src/Unix
$ ./autogen.sh
$ make

After that, for emulating Mac II si, you can use the system 7.0 disk image from here: http://www.emaculation.com/System70_boot.zip
Or, You can use system 7.5.3, whichever you like. 
If, you're using Basilisk GUI on linux, Mac OS X or Windows (I use CLI), you can find the relevant instructions here: http://www.emaculation.com/doku.php/basiliskii_linux_setup
http://www.emaculation.com/doku.php/basiliskii_osx_setup
http://www.emaculation.com/doku.php/basilisk_ii_setup

I downloaded the ROMs from: https://ia802503.us.archive.org/14/items/mac_rom_archive_-_as_of_8-19-2011/mac_rom_archive_-_as_of_8-19-2011.zip

After you're done setting it up, you can launch it using CLI (replace the PATHs relative to your own system):

BasiliskII --disk /extra/System70_boot.dsk --rom /extra/macrom/36B7FB6C\ -\ Mac\ IIsi.ROM --ramsize 200000000 --disk /extra/mac68k.img --cdrom /extra/mac68k/releasedir/images/NetBSD-7.99.71-mac68k.iso --cpu 3

(Warning: using --modelid option for this particular model will result in a non bootable machine, you'll get stuck at the boot screen.)

After that, for installing NetBSD you can follow the instructions from:
http://ftp.netbsd.org/pub/NetBSD/NetBSD-7.1/mac68k/INSTALL.html#Installing the NetBSD System (Sysinst Method)

 Basilisk II doesn't emulate an 68k MMU, so it cannot run NetBSD.

 Here's an excerpt from the output of BasiliskII --help:

  --cpu NUMBER
     CPU type (0 = 68000, 1 = 68010 etc.) [default=0]

 Isn't that the 68k MMU?
 Also, you can see the specs for Mac II si right here:
 http://www.everymac.com/systems/apple/mac_ii/specs/mac_iisi.html
 It has the 68030 processor.

 Thanking you,
 Utkarsh Anand

 No. Basilisk II emulates the Macintosh 68k platform (some virtual=20
 hardware + ROM, as far as necessary for the Macintosh OS), and not the=20
 actual Macintosh hardware. See e.g.=20
 <https://sourceforge.net/p/basilisk/mailman/message/2164622/>.

 Supporting the cpu's command set does not (necessarily) mean mmu=20
 support.

 Again: Basilisk does not provide the raw hardware emulation necessary=20
 to run anything but the Macintosh System. Which is a restriction of=20
 Basilisk, not one (and much less a bug) of NetBSD.

 Cheerio,

 For the 68020 there is an external MMU chip, the 68030,040,060 have an
 MMU built in. But that's the real hardware.

 Basilisk II only emulates enough to run MacOS.

 On the other hand its CPU emulation is based on some revision of UAE
 and recent (Win)UAE emulates the MMU. With enough effort you could
 teach Basilisk the necessary changes and then run NetBSD/mac68k.
