NE1000
The NE1000 and NE2000 are members of an early line of low cost Ethernet network cards introduced by Novell in 1987. Its popularity had a significant impact on the pervasiveness of networks in computing. They are based on a National Semiconductor prototype design using their 8390 Ethernet chip. History. In the late 1980s, Novell was looking to shed its hardware server business and transform its flagship NetWare product into a PC-based server operating system that was agnostic and independent of the physical network implementation and topology (Novell even referred to NetWare as a NOS, or "network operating system ). To do this, Novell needed networking technology in general — and networking cards in particular — to become a commodity, so that the server operating system and protocols would become the differentiating technology. Most of the key pieces of this strategy were already in place: Ethernet and Token Ring (among others) had been codified by the IEEE 802 standards committee — the draft was not formally adopted until 1990, but was already in widespread use, and cards from one vendor were, on the whole, wire-compatible with cards complying with the same 802 working group. However, networking hardware vendors in general, and industry 	NE1000

In order to create these at minimal R&D, engineering and production costs, Novell based their board on DP839EB, a reference design created by National Semiconductor using the 8390 Ethernet chip. Compared to the reference design, Novell used Programmed I/O instead of the slower ISA DMA. Novell’s design also didn’t map the card’s internal buffer RAM into the host’s address space. The original card, the NE1000 (8-bit ISA; announced as 	NE1000

It uses thin Ethernet; the second ("B") revision added an Attachment Unit Interface (AUI) port to support a transceiver, and later models NE1000T and NE2000T added built-in 10BASE-T support. With the launch of the NE1000 and NE2000, Novell took two significant steps. The first was a program under which other vendors were invited to manufacture the cards with no royalty as "NE1000-compatible" cards. Vendors were  required to submit their cards to Novell for certification which focused on whether the standard Novell driver worked with the card. Interested manufacturers were given a complete package of manufacturing documentation to allow them to start building NE1000/2000 compatible cards without having to do any design work. The primary intent of this program was to drive down the cost of network hardware to promote the adoption of PC networking. The second innovation taken, primarily to deal with internal management issues, was to allow Novell's distributors to buy the cards directly from its manufacturer, Eagle, a contract manufacturing subsidiary of  Anthem Technologies, the industrial distributor which provided the components for the NE1000/2000. Novell received a royalty on each card, but was no longer involved in scheduling and ordering manufacturing. In order to remain competitive with Novell's bargain-price cards, 3Com and other vendors were forced to cut the pricing of their entry-level network cards, contributing greatly to the networking boom of the 1990s. To a lesser extent, it is arguable that the success of the NE1000/2000 cards helped to tip the scale of the "LAN wars" in favor of Ethernet (championed by 3Com) over Token Ring (championed by  IBM), though its main impact was to significantly lower the cost of PC networks. In 2003 National Semiconductor ceased manufacturing of the 8390 chip. Clones. Many other manufacturers copied the design labeling under their own brand, while still claiming NE1000/NE2000 compatibility. However, in reality, this was not always the case. For instance, the Winbond 83C901 ignores the reset signal. Supported operating systems. Besides NetWare, driver support for these cards was (and still is) available for a variety of operating systems, including DOS, Microsoft Windows, UNIX, FreeBSD, QNX, and Linux. Note that Windows XP does not support non-Plug and  Play versions and Windows Vista does not support the NE2000 at all. Windows 2000 appears to have a working driver.
