Let me share my joy with you! After weeks and weeks of trying i have got the linux box at work networked. I'm sitting here with such a grin on my face. First I changed the DLink card for a 3com. Then I struggled with addresses and finally changed the io and irq on the card and matched up the box. Then i fiddled and diddled for ages not seeing what i had done wrong. Then SomeOne Who Knows looked at my box and found out it was using the AUI port rather than the BNC. Then I tried a 3c5x9config utility debian has but got tied in knots. Finally i did the boot-into-dos trick, and ran a 3com config exe file and changed the port. Now it pings, pongs, pangs. Happiness. Joy. Rapture. (sad, sad)
