Abit BP6 system will not POST

[owen at nerdnetworks.org (Owen B. Mehegan)]

I knew about this problem when I first got the board, and performed the
necessary modification to work around it. I had to do it to my first BP6
board which I bought a year and a half ago, so I was prepared when I got the
second one :) The VTT voltage has been fine since I modified the board.

Also, in response to those who suggested I try a UPS, I've always used one
with this system, so I don't think power line conditions are the problem.

Last night I replaced the power supply with a known-good one, and still had
the same problems, so it looks like I've eliminated that factor as well.
Hopefully I'll have more time tonight to experiment. Thanks again everyone
:)

Owen,

Some BP6 boards (rev 1.1 ver 0.41) have a defective power capacitor (see
http://www.eecg.toronto.edu/~doylep/linux-bp6/). Also if you go into the
BIOS
( if you can get that far) see if the  the voltages are stable (VTT should
not fluctuate more than 0.35  -.5 V) . See
http://bp6.gamesquad.net/Q6fix.phtml for some information.
