- The distributed Linux only supports the WD8003 and WD8013 (a.k.a. SMC
- Elite) ethercards.
-
- I've written drivers for many other ethercards; those drivers are
- available on usra.edu and super.org. The slightly-crufty stable
- versions are in pub/linux/ethercards/*, and the cleaned-up but
- not-fully-tested versions are in pub/linux/newether.
-
- This section should probably be put into a FAQ.
-
- The least expensive 8 bit ethercards start at $70 and are usually
- NE1000 clones. It's definitely worth it to pay an extra $10 and go
- for a 16 bit bus interface NE2000 clone. For another $10-$15 you can
- get a shared memory 8013 clone, which will give you somewhat higher
- system performance.
-
- You should expect to pay more than the price I listed above unless you
- do careful shopping from the back of Computer Shopper and (even
- better) LAN magazine. I've gotten network things from both MCW
- Distributors in Gaitherburg MD (good prices, sort of local, advertises
- in Comp.Shop.) and Network Express (a little more expensive).
-
- You'll also have to decide the kind of interface you need. "Thinnet"
- is RG58A 50ohm cable with BNC connectors. 10BaseT is twisted pair
- ("TP") to a central "hub". There is also traditional thick 50ohm
- cable, but it has no advantage in most installations. An "AUI" port
- is a 15 pin D-shell connector that can be hooked to an external
- transceiver (ca. $50 for 10BaseT or thinnet), usually for thicknet
- (in which case it's $100+). Cards typically have an AUI connector and
- either a thinnet or twisted pair transceiver. You'll pay about $20
- more and give up the AUI to get both thinnet and 10BaseT.
-
- Some ethercards advertise status LED. These are most useful for
- 10BaseT connections, which are easy to mix up.
-
- IMO, thinnet with on-card transceivers results in a _much_ cheaper
- system. You only need to buy T connectors($3ea.), cables ($6/12ft at
- RS), and two terminators ($2ea.), leading to a per-node cost of under
- $100. At these price levels it's definitely cheap enough to put on a
- home system! With twisted pair you'll need a hub which can easily
- double your per-node code. TP is only cost-effective if the wiring is
- already there and its expensive to run more.
-
-
- These drivers support all common 8390-based ethernet boards. Currently
- "common" is defined as:
-
- 3Com Products:
- * 3Com 3c503 Board loaned by Chance Reschke, USRA.edu (thanks!)
- 3Com 3c503/16 and excellent documentation provided by 3Com.
-
- Clones-n-things
- NE1000 Novell and Eagle are useless for documentation,
- * NE2000 but copied the designs directly from NatSemi;->.
- * Alta Combo(NE2000 clone)
- Aritsoft LANtastic AE-2 (NE2000 clone w/ extra memory)
- D-Link Ethernet II
-
- Cabletron products:
- E1010 No ID PROM and sketchy info from Ctron means you'll
- E1010-x have to compile-in information about your board.
- E2010
- E2010-x
- Until Cabletron responds with the documentation of their other
- ethercards I can't do anything. Doesn't anyone at ctron.com know how
- their own cards work?
-
- WD/SMC products
- WD8003
- * WD8013 Board loaned by Russ Nelson, Crynwr Software. Thanks!
-
- HP LAN adaptors
- ** HP27245
- ** HP27247A 'A' model only -- the 'B' is known to _not_ work!
- ** HP27250
-
- Thanks are due to hundred or so alpha testers. Special thanks to
- Chance Reschke <@usra.edu> and Russ Nelson <@crynwr.com> for loaning
- me ethercards, and USRA.edu for providing anonyous FTP space.
