<p><b>Berkeley Software Design, Inc.</b> (<b>BSDI</b> or, later, <b>BSDi</b>), was a <a href="Software" title="Software">software</a> company founded in 1991 by members of the <a href="Computer_Systems_Research_Group" title="Computer Systems Research Group">Computer Systems Research Group</a> (CSRG), known for developing and selling <a href="BSD/OS" title="BSD/OS">BSD/OS</a> (originally known as BSD/386), a commercial and partially <a href="Proprietary_software" title="Proprietary software">proprietary</a> variant of the <a href="Berkeley_Software_Distribution" title="Berkeley Software Distribution">BSD Unix</a> <a href="Operating_system" title="Operating system">operating system</a> for <a href="PC_compatible" class="mw-redirect" title="PC compatible">PCs</a>.

</p><p>BSD/386 was released in January 1992. The name was chosen for its similarity to BSD ("Berkeley Software Distribution"), the source of its primary product, specifically <a href="4.3BSD" class="mw-redirect" title="4.3BSD">4.3BSD</a> Networking Release 2 (Net/2). The full system, including <a href="Source_code" title="Source code">source code</a> retailed at $995, which was more affordable than the equivalent source code license for the rival <a href="UNIX_System_V" title="UNIX System V">UNIX System V</a> from <a href="AT%26T" title="AT&T">AT&T</a> (which cost more than $20,000 in the late 1980s.)<sup id="cite_ref-McKusick_4-0" class="reference"><a href="#cite_note-McKusick-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="USL_v._BSDI_lawsuit"><i>USL v. BSDI</i> lawsuit</h2></div>

<p>In late 1991, AT&T's <a href="Unix_System_Laboratories" title="Unix System Laboratories">Unix System Laboratories</a> (USL) brought a <a href="USL_v._BSDI" class="mw-redirect" title="USL v. BSDI">lawsuit against BSDI</a>, alleging that BSD/386 contained their proprietary trade secrets and source code. When USL were acquired by <a href="Novell" title="Novell">Novell</a>, a settlement was reached in January 1994. BSDI agreed to base future releases of the product, now called BSD/OS, on the CSRG's <a href="4.4BSD-Lite" class="mw-redirect" title="4.4BSD-Lite">4.4BSD-Lite</a> release which was declared free of any USL intellectual property.<sup id="cite_ref-McKusick_4-1" class="reference"><a href="#cite_note-McKusick-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Rob Kolstad (of the University of Illinois and Convex Computer Corporation) was president of BSDI during this period and headed the company until the close of the decade.

</p>

<div class="mw-heading mw-heading2"><h2 id="Usage_in_infrastructure">Usage in infrastructure</h2></div>

<p>Under Rob Kolstad's direction, the company decided to pursue internet infrastructure as their primary customer audience. In the mid 1990s the top-10 websites in the world were almost all using BSD/386 as their BSD source codebase.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>

</p><p>In the 1995 a survey of datacenter software platforms disclosed that BSDI was the #1 software used in data centers, by Internet servers. BSDI subsequently released an "Internet Server" version of their software, in contrast to the desktop version, which focused on providing the maximum number of open-source server products in the base distribution.

</p>

<div class="mw-heading mw-heading2"><h2 id="Mergers_and_sale">Mergers and sale</h2></div>

<p>In 1999, the BSDI employees sought an <a href="Initial_public_offering" title="Initial public offering">initial public offering</a> and installed a new president to reach this goal as soon as possible given the recent success of the <a href="Red_Hat" title="Red Hat">Red Hat</a> IPO in the <a href="Linux" title="Linux">Linux</a> market. Unfortunately, this strategy was not successful and soon after Rob Kolstad had exited the company, it was facing bankruptcy.

</p><p>In 2000 the company merged with <a href="Walnut_Creek_CDROM" title="Walnut Creek CDROM">Walnut Creek CDROM</a>, a distributor of <a href="Freeware" title="Freeware">freeware</a> and <a href="Open_source_software" class="mw-redirect" title="Open source software">open source software</a> on <a href="CD-ROM" title="CD-ROM">CD-ROM</a> and shortly after that acquired Telenet System Solutions, Inc., an <a href="Internet" title="Internet">Internet</a> infrastructure server supplier.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>

</p><p>In 2001, under severe financial pressure from excessive leverage, BSDI (known as BSDi by that time) sold its software business unit (comprising BSD/OS and the former Walnut Creek <a href="FreeBSD" title="FreeBSD">FreeBSD</a> and <a href="Slackware_Linux" class="mw-redirect" title="Slackware Linux">Slackware Linux</a> open source offerings) to <a href="Wind_River_Systems" title="Wind River Systems">Wind River Systems</a> and renamed the remainder <a href="IXsystems" title="IXsystems">iXsystems</a> with a renewed focus on server hardware.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> Wind River dropped sponsorship of Slackware soon afterwards<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> and the FreeBSD unit was divested as a separate entity FreeBSD Mall, Inc. in 2002.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> Faced with competition from open-source BSD- and Linux-based operating systems, Wind River discontinued BSD/OS in December 2003.
