i just got a new motherboard/processor. (amd 4x3.4ghz
with sb850) it just worked. boots in 10 seconds. same
old crappy plan 9 video perfomance. :-) its been a long
time since i didn't need to fight a motherboard. i did
notice this usb niggle when booting. i haven't tried usb
yet, so i don't know if this means anything at all:

oh, and yes. when pulling the old motherboard i noticed
about 2/3 of the caps are dripping.

I wonder how that happened? Every hardware problem I have diagnosed
and occasionally fixed in the last few years, from motherboards to CRT
monitors to external power supplies (mains voltage converters) has
boiled down to one or more 10μF electrolytics packing up. How many
faulty capacitors were manufactured and deployed? By whom?
Intentionally?

these are 6.6v 1800µF caps. see http://en.wikipedia.org/wiki/Capacitor_plague

Its not faulty caps, they just have a limited life,
dried up electrolytic caps is the cause of most
electronics dieing of old age.

In the days before I took up electronics as a hobby, valves were
seated in sockets because it was known that the equipment they were
used in would outlive them. Maybe we should recommend easily
replaceable capacitors in modern equipment instead of blindly
accepting that a component of extremely low cost should wreck
expensive machinery beyond repair.

Cheap caps don't last, expensive ones do. No-one's going to put cheap
caps in sockets, it defeats the point of using cheap ones. Cap
replacement is still possible if you have some skill with a soldering
iron, or see http://badcaps.net/ . That said, adequate caps are often
larger than cheap ones.

is that lifetime 2 years?
i have 3 va linux machines here that are still working great
with no leaky caps. they are all about 12 years old.
(by the way, the motherboard + processor + memory
is free to a good plan 9 home. you pay shipping.)
