I'm interested in hearing of any experiences (good or bad) people have had with WD800E ethernet cards. Over the last few months, I've been installing these in Unix boxes of various flavours, mainly 25MHZ and below. However, with one 386/33 model and, more recently, a Compaq 486, I've found them very unreliable - in fact, downright troublesome. With the 386/33 (a Micronic board), we had the occasional "panic trap" 0x0000000E. It was annoying, but only occasionally. The machine ran Interactive Unix 2.0.2, subsequently upgraded to 2.2. Same problems - though slowing down the bus speed seems to have solved that problem - or at least reduced it's effect to almost negligable. The TCP/IP installed was also Interactive's. With the Compaq, we are using SCO Unix/386, with SCO's TCP/IP 1.1.1. EXACTLY the same problem - kernel panic traps. This time, it occurs reliably within 20 seconds of attempting any traffic across the net (probably related to a timeout?). After a frustrating hour of trying different card configurations (all the same results), we ended up replacing it with a 3COM 3C501, which worked first time, every time. Never seen a panic trap since. BTW, the Compaq has an EISA bus. Now, the question arises as to the cause. Is this simply a hardware problem on the WD8003 itself (we tried just about all of the models available - including some manufactured 3 years ago, to the more recent ones with software configuration with no change in the symptoms) or is it a bug in the (common?) driver related to running on a faster bus. Or is it just a coincidence? I use two of these cards myself and haven't had a problem; but of course, I'm only running a 20MHZ 386. - david -- Fidonet: 3:632/348 SIGnet: 28:4100/1 Imex: 90:833/387 Data: +61-3-885-7864 Voice: +61-3-826-6711 Internet/ACSnet: david@csource.oz.au Uucp: ..!uunet!munnari!csource!david

We still have ISC 2.0.2 are running 1 Machine with a 600 MB drive as NFS-Server. We have started with Ni5210 MICOM Cards but we had problems to run NFS with it. So we changed to WD8003 ethernet cards an everything runs well since today. The NFS only seems to slow down the systems significantly. - peter Peter Langen, Lehrstuhl Informatik IV RWTH-Aachen, D-W5100 Aachen, Germany goofy@informatik.rwth-aachen.de
