Thanks for the info. For the record I have a PowerPC 7200/120 and was wondering if any other extended ethernet users have this same problem. The network works but is incredibly slow do to the resetting every second. I really don't think the network ever was completely hung... just very very slow ..like 10,100,1000 times slower than all the other non-mace machines. I talked to Apple (they just told me the only known problem is with certain 7200/90 machines (see http://til.info.apple.com/techinfo.nsf/artnum/n18944) . I guess this is the issue Keith mentioned in a previous post. I ask them to review there database and search for any ethernet issues for 7200/120 and they claimed there are no known ethernet problems. I guess my question to you, Paul, is what do I need to do to the mace.c file to turn off the resetting of the chip. I am just guessing that the reset condition you looked for does not hang the mace chip in the 7200/120. If so then removing the reset should fix my problem. I am again assuming the the mace chip in my 7200/120 hardware does not hang. If I remove the resetting and it hangs then well I just have to but a PCI ethernet card.
