If I'm following correctly Jeroen's problem is with genuine Intel Etherexpress Pro boards with the '59 chip. Not with an integrated chipset as discussed in the above URL. Intel offers an interesting diagnostic suggestions: if it doesn't work with a short wire, try a long wire. Suspect Jeroen's most timely solution is to permanently replace his cards with something else. Altho he makes mention of a PCI riser card which may alter the electrical reference the Intel card has to work against. Am also thinking the computer power supply, or clock frequency can be part of the problem. Or part of the solution. Wonder if underclocking the system would make any differnce? Have seen unreliable computers fixed by replacing the PS. And this was before CPU's started running off of anything other than plain old 5V. As for non-Intel ethernet cards, 3 or 4 years ago when I first got to play with fast ethernet, found by accident that a 3Com card connected to a 3Com switch was more forgiving of wrongly pairing the cat5 wires than anything else connected to the same switch and wire. IMHO am surprised this sort of thing doesn't happen more often. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
