There are a few people who use Linux in this kind of environment - I once met someone who found out it was cheaper to get a load of P200 machines plus an 100BaseTX network and install linux, and some processor sharing software, rather than buy a supercomputer.

It seems you've got a RJ-45 connector for 10BaseT networking onboard, while the card has a BNC and an AUI. Ah. Not easy, you could buy a protocol convertor to convert 10BaseT (RJ-45/phone connector) to 10Base2 (BNC/coax), but it would be cheaper to buy a combo network card for about 20 quid new. You'd use a UTP crossover cable (not a straight patch cable) to connect the two machines - they're available from Maplin's, etc. If you want to use more than two machines, you'd need a hub for 10BaseT. ..........................................................................

Can't say really as it depends on what the host OS was. It's probably rather difficult.

Basically you convert the subnet mask to a binary number, so you get 11111111 11111111 11111000 00000000 The 1's indicate the bits that don't change within the network segment (etc.) - the 0 bits are used to indicate the actual machine number. Many networks will use 255.255.255.0 to have 254 addresses in the network. Your network number is 10 . 16 . 72 . 0 00001010 00010000 01001000 00000000 ------------ The underlined portion can then be changed to indicate a machine number - so you basically have 11 bits of addressing - i.e 2^11, 2048 addresses (minus the broadcast address, etc) Of course, you don't need to work all this out when assigning IP numbers, just assign a number of the form 10.16.(72-79).(0-255), and give out your subnet mask of 255.255.248.0 and network address of 10.16.72.0 (for default routing) Will --- FMailX32 1.22 * Origin: wth@pinpoint.craybbs.co.uk (2:254/211.20) --------------- FIDO MESSAGE AREA==> TOPIC: 193 LAN Ref: F1F00010 Date: 01/10/98 From: SCOTT PARKS Time: 08:51am \/To: LOUIE TARPO (Read 3 times) Subj: anyone recognise this?

Removing the Prom and/or using the software setup for the card to change the option ... will remove that question. To boot from the network requires a boot image that has to be made with a utility that comes with the Prom. It's a single file usually made from a floppy and the name to look for can be defined in your NIC card setup. I believe it goes in your Login directory (Netware) ... but it's been awhile. --- GEcho 1.11+ * Origin: (1:343/70) --------------- FIDO MESSAGE AREA==> TOPIC: 193 LAN Ref: F1F00011 Date: 01/10/98 From: SCOTT PARKS Time: 09:06am \/To: BRUCE LEGRANDE (Read 3 times) Subj: RJ-45 # or Cond ?

I have three segments now. One 100 and two 10BTs. They run off a trio of 3Com 59X5 PCI cards on IRQ's 3, 5, and 7 (printers are off workstations). The two on-board controllers (HP LH 133 server) and tape controller (Adaptec 2940) all run on IRQ 10. Do you really think I could take a hub and twelve users and put it on another NIC? Would that really make the users happy? Some of them copy 20-30 megs of stuff on and off the server at a clip. And it's easy for them to bury the server at 100% for several minutes at time.
