Sorry, but i have ONLY COMPLIMENTS FOR YOU. If you lost followers or viewers (this people doesn't know what is good). Excellent work. AS ALWAYS. Keep doing what you do. You show in all the videos more than a repair, is the love for the good work repairing this motherboards in this case, but i follow you for a while, and is constant, not only for this serie. GREAT WORK. (My like and i am already subscribed)

Great Job! Nice to see more vintage hardware saved from the scrap pile.Thank you for the Videos.

[@Fallen608]

Your videos are always a comfy watch. Years ago in the early 00's my late father and I threw away a mountain of old computer gear from the 90s. Only later in life did I regret that decision as I now have such nostalgia for computer hardware and games of that era and I love fixing things. Keep up the great content, You have inspired me to finally get into board level repairs. I'll try to use your affiliate links as a thanks.

ESR on the first cap is 0.15 KILO ohm! 150 Ohm - that cap is gone! I need an engraving pen :)

[@bitsundbolts]

Haha, yes! I totally missed that it was KILO ohms! And I know why you need that engraving pen! You liked how it flipped those SMD capacitors off the board, didn't you????

[@tony359]

@@bitsundbolts that was cool but no, I just like how nicely you can polish traces without polish the whole area. The rubber thing I have is great and probably gentler but it takes away chunks of solder mask

[@dolphhandcreme]

2:10 Did you notice the "K" before the Ohm? This is everything but a low ESR ;-) BTW the Atten is a good rework station! Bought it a year ago to replace my old cheap one.

[@bitsundbolts]

I did not notice it :) Someone else mentioned it. I guess I completely ignored the unit... Of course, this is not low ESR :) I like the Atten - I used it to get some connectors off those donor boards, but I also like to try my luck with the chipset on them. BGA rework is something I want to get good at.

[@dolphhandcreme]

@@bitsundbolts BGA rework can be quite satisfying or mood-destroying. I practiced on some old routers and graphic cards. Worked quite well. Later on i tried fixing a 430HX board (GA586DX) - which unfortunately didn't work out. I also had to repair some ripped pads and use soldermask. Can't figure out why, maybe something else is fishy with this board. My last project was reviving a AM4 motherboard where the X570-chipset was dead. This on the other hand worked like a charm and gave me great confidence in my work again. It's a hit-and-miss sometimes, but practice helps a lot!

[@AladimBR]

I didn’t comment on the previous video when you changed the capacitors and most were ok. Imho, it is worth replacing if you value the component. Here is why: you know don’t when it going to fail: it can leak and eat away components beyond repair (this video just demonstrated the potential damage), they can fail and cause electrical damage to other components, etc. They might be ok today, but for how long? A recapped board with good quality components will last another 20 years. Congratulations on the series, I loved it. PS: I checked my Soyo board, didn’t find any loose power elements (mosfets). I hoped it was the case. Back to storage waiting for a new inspiration / idea

[@bitsundbolts]

Yes, you're right. There will be a time where those caps are going to fail. It is still remarkable that the caps on those boards seem to be ok for now. But who knows for how long. Could be a couple of years, but I have a feeling that they'll be fine for much longer considering that those boards probably won't be used for long periods of time.

That was a cool series. It's amazing that you were able to fix them all

[@FireballXL55]

Removing the 20 pin PSU connector you probably could have a spare mating half plugged in to aid removal, although in this case it seemed to come out OK. I have loved watching your revival of these boards.

[@peterkornaukhov9990]

It seems to me the P2B user is able to upgrade up to Celeron 1400 tualatin not Pentium III because the mobo supports 100 Mhz not 133 frontside. This is very good, meanwhile not comparable to P4 and so far it can be a perspective and a free maneuver. Thank you so much, awesome video

I think I still have same board in my PBX "PC" running trixbox (asterisk based PBX distributive). It still is running 24/7 for over 15 years at least. (Yeah, it was used for another 10 years at least before being installed into my PBX PC. I did replace power supply unit though, like 3 years ago. Or even more.

That board uses those bad blue no name caps like the one that exploded and not that light green Sanyo ones you replaced at the previous board. Consider putting the Sanyo ones you removed to this board cause maybe another blue one may release its guts in the near future Great work again! Cheers and I saw all videos...

[@bitsundbolts]

Wow! Making it through all six videos is quite the achievement ☺️. There should be a badge for this!

[@awilliams1701]

Yeah this is why I believe in replacing 30 year old capacitors even if they are still good. Because if they go bad it requires more work to fix. It's a preventative maintenance thing.

[@bitsundbolts]

I get your point! This wasn't fun to clean up. Especially that it can be prevented. But I find it odd that this was the only capacitor that leaked. Every other capacitor on this board and the other five boards was ok.

[@metalworksmachineshop]

I watched all 6 restored board videos. Love the content. I'd like to have one , but I'm sure shipping would cost more than the board is worth shipped to Ohio USA

[@bitsundbolts]

Shipping cost is the main deterrent of me shipping things around. It cost about 25 USD to ship to USA, but I might find a solution to this given enough time.

[@DefenderOfBoston-yo2tl]

Amazing job, congratulations! Initially looking at these boards, I would have expected at least one of them to have lost an irreplaceable component that would have relegated it to become a donor board for some of the others. Fortes fortuna adiuvat! However, your final boss still awaits... 😄😉 Doing a bit of "research", I only recently discovered that there was a version of this board supporting dual CPUs and containing an onboard SCSI controller, the P2B-DS. The thought of dual CPUs really appealed to me back in the day, starting with the Tyan Tomcat IV. Being that far ahead of their time, Multi-Core setups wouldn't have been much use for gaming and therefore just an expensive disappointment though I suppose.

[@bitsundbolts]

Thank you! I have to start looking into the dual slot CPU I pulled from a pile of boards a few months ago. I never had an encounter with tech like this back in the day.

[@DefenderOfBoston-yo2tl]

@@bitsundbolts Oh, did you feature such a board among your scrapyard finds? In that case, I must be getting old. 😅 As they were purely business oriented products, I didn't directly come into contact with them either, but I remember seeing them in catalogues and fantasizing about their performance. It would be quite interesting to see how well dual CPU setups worked back in the day and what software could actually make use of them. If only as a confirmation that, contrary to my younger self's hopes, they would have been absolutely useless for gaming and not straight up twice as fast. 😄

[@lexluthermiester]

@BitUndBolts I was happy with each one of these P2B videos. Very cool stuff. But I'm a bit different and eccentric.. EDIT: BTW, again, very well done!! Looking forward to see what you do with a few of those boards!

I will post the link later, I hope I won't forget. I also got a bad one with a poor LCD display. I don't know why because all of them look the same. It's still kind of trial and error I fear. I'll put a link in the video description in a couple of hours. Thank you for watching!

[@SudosFTW]

WHat stands out to me is that one capacitor could have been hit with something corrosive which made it balloon like that. I have a Macintosh SE that still worked despite a battery going nuclear on the board, and the main takeaway with that machine was that it had chemicon axial caps that were ballooned and deformed so badly I could barely tell their values. This was more likely due to corrosion hitting that spot and wicking up into the capacitor and reacting with the electrolyte etc with age and time.

[@bitsundbolts]

I never saw a capacitor that had something like those boils. Maybe you are right. All the other boards also looked like something corrosive dropped on them.

[@alexj.f.kennedy6084]

Very nice series, was a blast to see you repair all these boards! One thing I am wondering tho: Why didn't you use vinnegar to combat the corrosion caused by the leaked capacitor? I saw it giving very good results, and I bet it would be faster than doing it with the engraving pen :D

[@bitsundbolts]

Ah it might not be obvious in the video, but I did use vinegar. It helps take debris away when using the engraving pen. Vinegar alone will probably not be enough. I remove discolored solder mask to make sure there's no corrosion left.

[@SianaGearz]

10:25 i wonder what made the video wobbly like that. Is that an anti rolling shutter filter or something like that?

[@bitsundbolts]

No... It's unfortunately my fume extractor 😔. It's on the desk right next to the board and one of the rubber legs touches the wooden work board. That is why the vibration is there and makes the video look like that. Unfortunately, I noticed it too late

[@Ale.K7]

Loved the series :-)

[@MarcoGPUtuber]

10:58 I see a solder bridge at 7:55 on the two caps on the bottom right. I guess that didn't affect anything?

[@bitsundbolts]

That bridge is actually also on the board. There are two differently spec'd capacitors, one in the low pF and one with uF. If I am not mistaken, they filter different frequencies.

[@romanrm1]

I believe "the ASUS chip" might be responsible for hardware monitoring of temperatures and voltages, so you'd better check that part is working, before declaring the motherboard fixed. Also if that's the case, it is most likely the motherboard would still POST and work with the ASUS chip removed entirely.

[@bitsundbolts]

All boards report voltages and the motherboard temperature correctly in the BIOS hardware monitor. Of course, I could have missed something like the additional connectors for measuring additional temperatures (I don't have the original temperature probe), but chances are low since the other values are there.

[@alexloktionoff6833]

Run 1.2GHz Tualatin Celeron then?

[@bitsundbolts]

I am not entirely certain, but I believe I would have to mod an adapter card to get Tualatin CPUs working on slot 1. Maybe something I'll try to do in the future.

[@awilliams1701]

Was this the only one that worked first try?

[@bitsundbolts]

Yes, but I had two or three other boards that just needed a bit of contact cleaner in the CPU slot. I learned from those and prepared properly this time. And it worked - first try! :)

@@bitsundbolts I had to go back and look at the start again, It didn't click in my brain until you stacked them at the end.

[@mariusznowakowski2644]

These boards were professional, they were repaired as in the service center, but the faults were not difficult to repair, it would be difficult to repair if one of the bridges collapsed and the BGA would have to be replaced.

[@bitsundbolts]

I agree - it was only physical damage. I want to practice more on BGA replacement - using a hot air station only. I don't have space for a BGA rework station - so, I need to master that craft with basic equipment.
