    9: NetBSD/sun3 is the port of NetBSD to the Sun Microsystems sun3, and sun3x series of computers, which are based on the Motorola [68020](http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC68020) and [68030](http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC68030) CPUs respectively, with a Sun-designed custom MMU. Sun sold these computers as both servers and desktop workstations from the mid to late 1980's. They were superseded by the sun4 SPARC RISC systems, which are supported by NetBSD as [NetBSD/sparc](/ports/sparc).
   10: 
   11: Nathan Williams and Jeremy Cooper are the maintainers of NetBSD/sun3.

  103: 
  104: The RAM column is maximum supported RAM in megabytes.
  105: 
  106: Sun made a variety of VME bus cabinets with different numbers of bus slots; ultimate RAM and I/O expansion is more a matter of how many bus slots there, rather than the particular CPU you have.
  107: 
  108: The Sun3/80 RAM capacity varies with the boot ROM revision - 3.0.2 allows 40MB, 3.0.3 allows 64MB.
  109: 
  110: The Sun 3/50 has 4MB soldered on the motherboard; all RAM expansions for that workstation were provided by third-party solutions (read "hacks") of one kind or another.
  111: 
  112: The Sun 3/E is a 6U VME single-board computer intended as an embedded system component.
  113: 
  114: The Sun 3/80 workstation and Sun 3/400 series servers are sun3x architecture machines based on the [Motorola 68030 CPU](http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC68030). They were Sun's last design using Motorola microprocessors, and were somewhat complicated by the fact that the mc68030 has an integrated MMU in the CPU chip.
  115: 
  116: Sun Microsystems stopped designing systems with Motorola microprocessors when their own SPARC CPU design became a commercial success. 
  117: 
  118: ###Disk and RAM Requirements
  119: 
  120: Minimum
  121: 
  122:     4MB RAM, ~80MB disk
  123: 
  124: Normal
  125: 
  126:     8MB RAM, 200MB disk
  127: 
  128: Normal + X11
  129: 
  130:     16MB RAM, 300MB disk
  131: 
  132: The complete NetBSD sources without objects require 200MB of disk.
  133: 
  134: To run the X Window System or compile the NetBSD system sources (i.e. development), more RAM and disk are recommended. Good performance requires 8MB of RAM, or 16MB of RAM when running the X Window System.
  135:

  255:                 <p> All sun3 and sun3x monitors support booting from SCSI devices. Most users
  256:                     will be familiar with booting from the monitor device <code class="code">sd(0,0,0)</code>,
  257:                     which they know means booting the SCSI disk at target zero. However, determining
  258:                     the monitor device name for booting an arbitrary SCSI device can be confusing. </p>
  259:                 <p> A monitor boot device takes the form
  260:                         <span class="emphasis"><em>dev</em></span><code class="code">(</code><span class="emphasis"><em>cntrl</em></span><code class="code">,</code><span class="emphasis"><em>unit</em></span><code class="code">,</code><span class="emphasis"><em>part</em></span><code class="code">)</code>.
  261:                         <span class="emphasis"><em>dev</em></span> is two letters, and <span class="emphasis"><em>cntrl</em></span>,
  262:                         <span class="emphasis"><em>unit</em></span>, and <span class="emphasis"><em>part</em></span> are hexadecimal
  263:                     numbers. </p>
  264:                 <p> For SCSI disks and CD-ROMs, <span class="emphasis"><em>dev</em></span> is <code class="code">sd</code>. For
  265:                     SCSI tapes, <span class="emphasis"><em>dev</em></span> is <code class="code">st</code>. </p>
  266:                 <p> For all SCSI devices, <span class="emphasis"><em>cntrl</em></span> is the number of the SCSI
  267:                     controller the device is attached to. For a machine with a single SCSI
  268:                     controller, <span class="emphasis"><em>cntrl</em></span> is <code class="code">0</code>. </p>
  269:                 <p> For all SCSI devices, <span class="emphasis"><em>unit</em></span> identifies the SCSI target
  270:                     and logical unit number of the device. Exactly how the SCSI target and logical
  271:                     unit number are combined into the single number <span class="emphasis"><em>unit</em></span>
  272:                     depends on your machine type and ROM revision, and whether or not the device is
  273:                     a disk, CD-ROM, or tape. Use the tables below to figure out how
  274:                     <span class="emphasis"><em>unit</em></span> works on your machine. </p>
  275:                 <p> For SCSI disks and CD-ROMs, <span class="emphasis"><em>part</em></span> selects the partition
  276:                     to boot on that disk or CD-ROM. The first partition is <code class="code">0</code>, the
  277:                     second partition is <code class="code">1</code>, etc. Normally, <span class="emphasis"><em>part</em></span> is
  278:                         <code class="code">0</code>, since the first partition on a disk is usually the bootable
  279:                     one. Common exceptions are booting a miniroot that has been written to the swap
  280:                     partition, in which case <span class="emphasis"><em>part</em></span> is <code class="code">1</code>, or booting
  281:                     a CD-ROM that contains different bootable partitions for different
  282:                     architectures, in which case you have to know which partition boots your
  283:                     architecture. </p>
  284:                 <p> For SCSI tapes, <span class="emphasis"><em>part</em></span> selects the tape segment (also
  285:                     called "tape file") to boot. The first tape segment is <code class="code">0</code>, the
  286:                     second tape segment is <code class="code">1</code>, etc. You will need to know which tape
  287:                     segment is bootable for your architecture in order to give the right
  288:                         <span class="emphasis"><em>part</em></span>. </p>
  289:                 <p> Finally, these are the tables that demonstrate how <span class="emphasis"><em>unit</em></span>
  290:                     works on various machines. They list <code class="code">sd</code> monitor devices for disks
  291:                     and CD-ROMs, and <code class="code">st</code> monitor devices for tapes, all at different
  292:                     SCSI targets. These tables assume that you want the first SCSI controller
  293:                         <code class="code">0</code>, and the first partition or first tape segment
  294:                     <code class="code">0</code>. Also, because many Sun 3 models use the same CPU board, to keep
  295:                     these tables simple Sun's CPU board code names are used wherever possible. </p>

  516:                 <p> The above tables also assume that you want SCSI logical unit number zero. The
  517:                     SCSI specification allows one SCSI target to contain different logical units
  518:                     (also called LUNs). Virtually no SCSI devices make use of this feature, and have
  519:                     only a single LUN, zero. However, if you know you have a disk at a LUN other
  520:                     than zero (early Sun SCSI disk setups do), you can add the LUN number to the
  521:                         <span class="emphasis"><em>unit</em></span> value, noting that <span class="emphasis"><em>unit</em></span> is a

  526:   </h4>
  527:                 <p> The sun3x port of NetBSD was initiated by two independent groups of
  528:                     developers. The first group, headed by Gordon Ross and Jeremy Cooper, began work
  529:                     in March of 1996 with the (then) current sun3 port and the intent to create a
  530:                     new pmap system that was not based on the hp300 m68k code. Their work is the
  531:                     officially supported version of NetBSD/sun3x. </p>
  532:                 <p> The second group, headed by Tsubai Masanari, also began with the sun3
  533:                     distribution but instead choose to use the traditional hp300 m68k pmap. This
  534:                     approach allowed them to get a fully running system in a matter of weeks. They
  535:                     were the first to successfully integrate the SPARC Enhanced SCSI Processor
  536:                     driver into the kernel, proving that the Sun3x was indeed half SPARC, half Sun3. </p>
  537:                 <p> Although the currently supported NetBSD/sun3x is based on Gordon and Jeremy's
  538:                     work, they are indebted to the second group for their innovation. </p>
  539:                 <p> Between NetBSD 1.3 and 1.4 NetBSD/sun3x was merged into NetBSD/sun3. They
  540:                     build separate kernels, but share the same userland, and kernel build tree.
