Well,
Abit has had the first of my bad BP6 motherboards for more than 2
weeks, and they still haven't shipped a repaired replacement, and they
aren't answering my email. So, getting desperate, I decided to recap
one of the motherboards myself, using the replacement capacitors which
Jackcon sent me.
It went pretty smoothly except for three problems:
Problem #1 (solved): I had trouble getting the solder out of the 48
tiny holes on the motherboard, after removing the 24 bad capacitors.
For your amusement, and with apologies to Tim "The Toolman" Taylor,
here are a couple of photos of my solution:

Yes, they are hooked "in series," with the bags removed for extra
power. They made a most impressive roar, lemme tell you! Note that the
power cords snake off in different directions, because I plugged them
into different circuits, so that they wouldn't trip a breaker.
Problem #2 (not solved): After I'd already removed about half of
the bad capacitors, I realized that the two small inductors, L17 and
L18, are also toasted. I don't know whether or not they are still
functional, but they sure look bad. Here are some pictures of them:

http://www.burtonsys.com/BP6_bad_coils2.jpg (after removing the bad capacitors)
http://www.burtonsys.com/BP6_bad_coils3.jpg (another view after removing the bad capacitors)
I don't have anything to replace them with, so I left them alone.
If I'd noticed them before starting on this project, I'd have left the
board alone and RMA'd it to Abit to worry about. I doubt that they'll
take it back, now. 
What do ya'all think? Are L17 and L18 gonners? Any idea where I can get replacements?
Problem #3 (the big one): It doesn't work. After replacing the
capacitors, I plugged in a couple of sticks of memory, a pair of CPUs,
video card, monitor, power supply, and keyboard. Then I turned on the
power supply, and momentarily jumpered the power switch connector. The
CPU fans started up, but nothing else happened. No POST at all. So I
hooked up a speaker to check for beep codes, and was rewarded with a
European police siren: Beep, Boop, Beep, Boop, etc.. So I powered down,
removed CPU #2, and powered up again: instant siren (no change). So I
powered down, and removed the other CPU, and tried powering it up with
no CPU: the siren again (no change).
Ideas, anyone?

Dave,
I don't be mad, but I was on the floor chuckling at the desoldering
'rig'.............. That's the best stroke of \"Macgyverism\" I've seen
in a LONG time!!! I NEVER use a solder sucker on a board, but rather a
needle pick to remove the solder, it's safer for the board. I'll take
some pics and post them for ya.
As far as coils, I have a BP6 I hosed a long time ago I've been
bilking parts off of, if u need the coils, let me know, I'll be happy
to send them to you. It still has all the coils in it.
As far as it working, if it is beeping at you, thats a really good
sign actually... That means it is trying, and things are for the most
part getting power. find out what beep code it is giving, and that will
tell you where the malfuntion it is. More than likely, the burt coils
have a hand in the problems...
Let me know if you want the coils!!

Oh, thank you, thank you, thank you! Yes, I do want the two small coils (L17 and L18).
As for the beeping... that's what I thought, too, at first: that it
must be BIOS beep codes. But it isn't. It is some sort of
hardware-generated alarm indicating that the CPUs aren't running. |

KILLER BEANS!! 
Glad I saved that old board, many times it nearly got pitched, but the
pack rat that I am always told myself I'll need something off it
someday...
Glad it worked!!

Well,
I was wrong. I didn't believe that the techs at Abit would replace only
some of the bad caps on a motherboard. But I just (finally!) got back
the RMA replacement for that BP6 that I sent 'em, and ten of its 1500uF
caps are still Tayeh, the other two are Teapo. So it sure looks like
they just pulled out a couple of visibly bad Tayeh caps and replaced
them with Teapo caps. Sheesh!
EC10 is just 100 uF, too.
The 1000uF caps are all gold-writing-on-black Teapos.
Big waste of time and shipping. I shoulda recapped it myself. |

| Well,
in the interest of fairness, I should mention that the RMA replacement
BP6 which Abit sent me does seem to work okay, in spite of the Tayeh
caps. I still would feel a lot better if they'd replaced 'em, but (for
now, anyhow) it runs fine. |
