The 100 Mbit card in the server would simply auto switch down to 10 Mbits, and you would be back to where you are now. To get the benefit of a 100 Mbit LAN, you will need either a 100 Mbit hub (and 100 Mbit cards in all the workstations as well) or a 10 Mbit multi-port switcher with a 100 Mbit back end connection to the 100 Mbit card in the server. Such hubs and switches are still very expensive, much more so than the new 100base TX Ethernet cards. Tore tore.hansen@bbs.logicnet.com -- CMPQwk 1.42-R2 391 ... I can fix it!

Thanks The AMD 586 chip is a 3.3V 486 pinout CPU that runs at 133 MHz internally, while the motherboard runs at 33 MHz. It is a true quadrupler (something Intel's dx4 is not), with some Pentium style super scalar enhancements. They are currently considered the poor mans Pentium around here, as you can get two 486dx133 motherboards for the price of one Pentium motherboard. Their performance is roughly equivalent to a 90 MHz Pentium CPU. Tore tore.hansen@bbs.logicnet.com -- CMPQwk 1.42-R2 391 ...

I hope he can fix it, i'm starting to discover that a couple of notorious bugs that have been pestering me for some time are being caused by Personal Netware. :( The bugs even had me doubting my hardware, tried all sorts of things, but somehow i never considered the fact that it could be PN.

I'm particulary proud of this one as I won the quote with by far the cheapest installation price. I used a cherry-picker to place the cable way up.

If the traffic is heavy, it may be a great idea for a fibre FDDI backbone, with either Tiger Hubs or some sort of switching hubs feeding each lab via either a router or a bridge.

There is a massive I beam along the top and the power goes along one side while the low voltage stuff goes on the other. Its seperation is about 50mm through the steel but about a metre around the I-beam. Arcnet is no better than coax or in fact, nearly anything else, with the proviso that it must be installed properly in the first place and maintained properly afterwards. Some proponents of both camps argue differently, however I have proven to my own satisfaction, and to engineering theory and practice, that a proper professional installation shows little to no difference to noise tolerance.

Fiber is expensive, but it is immune to electro magnetic interference, and very good where the data must be secured. Prices vary for the types you want. Contact a local communications contractor for details. You can get almost any hub equipment that will use Fiber at any level, from backbones, to workstation NICs. The support is there. The following probably explains the details best. I got this from a computer glossary program (Can't remember the name). FDDI (Fiber Distributed Data Interface) ANSI standard token passing network that uses optical fiber cabling and transmits at 100 Mbits/sec up to two kilometers. FDDI is used for MANs and LANs and includes its own network management standard called STM (Station Management). The TP-PMD (CDDI) version will run over copper (UTP), although limited to distances of typically 50 to 100 meters. FDDI provides network services at the same level as Ethernet and Token Ring (OSI layers 1 and 2). FDDI provides an optional "dual counter-rotating ring" topology that contains primary and secondary rings with data flowing in opposite directions. If the line breaks, the secondary ring is used to bypass the fault. Stations can be configured as Single Attached Stations (SAS) connected to concentrators, or as Dual Attached Stations (DAS), connected to both rings. Groups of stations are typically wired to concentrators connected in a hierarchical tree to the main ring. Large networks may be configured as a "dual ring of trees," in which the dual ring provides the backbone to which multiple hierarchies of concentrators are attached. FDDI provides a quantum jump in speed over 10 Mbps Ethernet and 16Mpbs Token Ring and allows high-resolution images to be quickly transmitted. See TP-PMD and CDDI. For a complimentary copy of a 456-page book on FDDI called "The Fiber Optic LAN HANDBOOK," contact Codenoll Corp., 1086 N. Broadway, Yonkers, NY 10701, 914/965-6300. --- * QMPro 1.53 * E=Mc^5..nah..E=Mc^4..nah..E=Mc^3..ah, the hell with it. --- WILDMAIL!/WC v4.12 * Origin: Aspencade BBS (1:226/0.0) --------------- FIDO MESSAGE AREA==> TOPIC: 193 LAN Ref: DDX00018 Date: 09/30/96 From: ERIC SMITH Time: 02:05pm \/To: KURT HILL (Read 5 times) Subj: NETWARE + LINUX...

Novell Netware has TCP/IP services that you can load up. Then just connect the UNIX or in this case LINUX server onto the network. You just ave to make sure of the IP addressing. Each station will have to have it's unique IP address specified in the NET.CFG file on each station. You will have to get a specific IP address for your network.
