Oh No... yea it still works but is very very slow so bad I can not even use
VNC !   Well this is miserable!  Thank you very much for the quick
response.  Looks like I will be buying a PCI ethernet card for my PowerMac
7200.  I just got it donated to me so guess I can't complain too much.
Does Apple know about the problem since mace is used with the built-in
ethernet?  I am sure this is asking too much but I will try ...will Apple
replace it?

I would still like to get a software fix for my problem? If possible?  Will
increasing the timeout value improve the problem?  It would if the software
detection of the timeout is bogus sometimes.  If the software detection of
this problem is always detecting the hardware hang then increasing the
timeout will just make it slower.  Any ideas ?

Also what company made the mace chip ... I am hardware designer myself and
I am very frustrated to see companies ship buggy hardware!  I work on
hardware for UNIX machines that must be 24x7 and  blazingly fast.  It is a
shame PC customers put up with buggy hardware/software!  (That is why
Windows/MacOS are still around.)  I guess rebooting your machine because of
lock ups or the blue screen death is acceptable... yea but the UNIX
customers do pay lots of bucks.  Sorry I had to vent my frustrations.
