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.
