I'm always learning from Mark. I really like how he sprinkles little bits of knowledge all over the place. Most interesting, this time, was the UEFItool.

Thanks! This is interesting and useful as usual. Don't mind the quality of the video, I care that you know what you are talking about and also explain what is going on.

Loved how you explained the capsule to rom extraction that really helped me

This is full of valuable info. Thanks for the crash course. Good stuff.

Glad to see you back.

I learned a LOT dude, this really helps me out diagnosing my dead motherboard, THANKS!

Thank you for all this amazing info, i also happen to have an OCZ PSU Fatal1ty 550 Watt which still works as it should and was used for 10 years straight before i upgraded, it still works, i just don't use the PC i have it on currently, even though i've cleaned its internals many times over the years i had to replace the fan cause it was too loud for my ears despite having near zero difficulty spinning.

Truly great video! Humorous and informative, just as all good things should be :D

First Duraga and now you Mark! What an amazing day!

SPI flash seems to rot pretty frequently. My Talos II had the uboot install rot through and cause the BMC to fail, luckily it was fixable with UART.

Excellent tips and repair! Thank you.

First off, immediate like for anything you post! Second, I couldn't wait until the end of the video to say as a 36 yo self taught, semi-advanced techie, I find this very educational as well as entertaining. Thank you show much for documenting and sharing the process. BTW, my pfSense router I built when I found your channel back in 2016 (I think) is still working great. It's running on an old Vista HP desktop MB. I never heard of pfSense before that. My stepdad even build one after loving mine and he's a programmer working for a big company on the FL Space Coast and was new to it also. Thank you, thank you, thank you for everything sir!

Great fix! Awesome to save from a landfill and now you got yourself a new server board. Luckily I just finished building a custom UnRAID Plex server with an Asus P11C-M/4 server board so I was actually able to follow along with the features that are available/standard on many server boards (I learned about IPMI and had to have it! LOL). I've learned a lot of things in the last few years of planning for that UnRAID build along with other projects. This video helped connect the dots on other things I've come across in electronics I've seen on BigCliveDotCom and Julian Illiet's channels.

Well done. I'm impressed, and that is a very hard thing to do.

ECC UDIMM is used in workstations and some server boards. The intel Server boards i use in my lab uses this ECC unbuffered RAM and its expensive unlike the Registered stuff. BIOS issue is a common thing on a lot of boards. I just use a BIOS re-programmer to solve the issues.

Most of Supermicro boards I encountered use UDIMMs, not RDIMM. And theses are real server ones, not ASUS, lol. RDIMMs are mostly for datacenter grade server platforms, rackmount chasis, non-standart formfactor server mobos focused on density. P8* / P9* series are workstation mobos. I had P9D-X and it refused to boot with LSI SAS HBA, which is an industry standard, unless I masked SMBus pins on its PCIe connector. What a joke..

Hi, what are these 4 square components on the left/bottom side of the fan assembly? My motherboard have 8 of these in a row but they were so close to the cpu that when I installed the cooler then it cause a slight damage to the side of those components, nothing serious and the board works but the case of these components is kid of cracked on 2 of these about 3 mm.

Great video. Gonna go dig out some of my faulty boards to play with now lol.

Very interesting educational video, thanks. In my (faulty) ASUS mobo, beside the soldered SMD ROM, there is an odd seven pins socket (eight pins but one has pulled off). Do you think I could exploit it to flash the BIOS? Anyway in my case this fix would be not reachable, because my mobo is stuck on unstable (oscillating) 5VSB. Power LED blinks every 4 secs. PWON does not start. On the other hand, CMOS clock works fine (DSO).

Best repair video ever!

Love the inductors tips

You made it look easy. Thank you!

Great video man.. I especially liked the part where you use raspberry pie to reflash the bios chip instead of using eeprom flasher. Is it possible also to reflash the bios chip using regular pc ports (ie. parallel ports) ?

Nice video and nice explanations, thanks!

Brilliantly done😊 Still laughing over the loud engine interruption 🤣 Currently trying to figure out why my ASUS Z10PE-D16 WS is crashing (no LED code even!) when 2nd Xeon installed. Your video has given me a couple more things to try - thanks!

Hey Mark. I've been watching a million videos trying to find out what the problem can be when the PC pass the CPU test but get stuck in Memory error. The PC has been working for years and now can't reach BIOS screen as for every boot it stops in mem_error. I tried every single stick, one at a time and in each slot at a time. I borrowed additional memory in case my sticks were bad but still same issue (none work in any slot). It happened before to need to boot 2 or three times to start the PC but then the issue went away. After months it came back and didn't work for a week, then after 2 weeks working the issue is back again and I never could boot it anymore. Any thoughts? Thank!! ASUS Sabertooth 990FX ver1

We miss you man. Come on back. All is forgiven. P.S. AVE would be proud of your TS skills.

Can a currupt bios chip still let you see your sata drives but cant install or boot from sata drives. I can boot from usb into a ubuntu OS running off that USB drive but cant install it to a sata drive or windows even though the system see's the drives

Hello, I have supermicro MBD-X5DPE-G2 board, It turns on but no post on screen and it just beeps what do I have to do ? I took the raid card out still nothing and the network card out still nothing.

Did you try the force bios recovery jumper and a USB stick offscreen before you broke out the breadboard?

I just got into fixing stuff. This helped alot. Thank you!

Nice repair

This teached me alot. Thanks for such a good vid.

Good time for an upload!

I think there was some arcane transient that crashed it and caused the rom to corrupt at once. At boot the rom is read and then never touched again, you can pull the chip out while it's running and it'll stay up, so I don't think the rom corrupting itself would have hung the machine (Though, maybe with this new fangled UEFI that is no longer true). At one point I abused this "feature" to use my motherboard as a general SPI programmer lol. I have since graduated(?) to using frser-duino on an $5 clone Arduino Uno, no Pi required.

I fully agree. I think something crashed hard which hung the machine and corrupted the ROM at the same time. If it was just the ROM it would have probably run fine until the next reboot.

I'm proud your experienced to troubleshoots a dead motherboard. That's the most underrated and comprehensive boardview of that moboard component part operations video tutorial ever so far. But I need help a quick question my friend about my Asus P4P800-E Deluxe motherboard. This is my first time trying to resurrect/repair my dead motherboard. Only certain part I repaired and changed/replaced already the (1) BIOS chip, (2) capacitors, (1) IC-driver controller to mosfet, and (2) transistor mosfets (negative side body) near side of the CPU processor. I have the PTi9 LCD PCI Diagnostic Analyzer Tester...indicates LED lights of +12V, +5V, +3.3V, and Reset are good (lights on) & fan runs means no problem on transistor Mosfets anymore as I double tested too that 12Volts are running good designed to run CPU processor. But the PTi9 LCD PCI Diagnostic Analyzer tester still telling me that there's signal error, it says check the CPU and power box (power supply is tested good all +12V, -12V, +5V & +3.3V) and the other two indicates that RST and FRAME are both Invalid shows in PTi9 tester. Also I'm seeing LED lights of FRAME, IRDY, and SYSClk are off, it shows in the PTi9 PCI Diagnostic Analyzer tester. I have the "Boardviewer" software (to see the schematic diagram of P4P800-E Deluxe board) that I clicked the CPU drawing part and looked at the RESET, looked at the motherboard then tested the Resistor that is soldered/connected on negative side that the value is correct that has no problem. The two pin reset (for the button reset) doesn't work when I pressed the button. If you have time, please try to look on the Boardview in part of the RESET pin because it's not working. I don't know about that FRAME & RST where to troubleshoot that. I touched the CPU processor it doesn't make any at least build up heat/warm. I tested the CPU processor from my other Asus motherboard, it's running fine. What part of the motherboard should I trouble shoot on that P4P800-E Deluxe? This part I'm lost already. I need help, any idea? Great help would be appreciated so much. Here's what I did, I plugged one 1GB stick ram, 3V battery button, fan for CPU, plugged-in the PTi9 Post Diagnostic Analyzer Tester, unplugged CPU processor and 12V-4-pins, then plugged the 20-pin power supply, then turn it on, everything runs even though it's unplugged CPU and 12Volts-4-pin. On the tester it shows LED lights on at the +12Volts, +5Volts, 3.3Volts, RST, CLK, except FRAME, IRDY, and SYSClk. So, it means the issue is at the Power Block of CPU because CPU doesn't build up warm/heat. Problem is still don't know where is the one that doesn't provide either the +5Volts or 3Volts or 1.2Volts. Intel 82865PE MCH Chipset build up its own heat but it has its own original heatsink since P4P800-E Deluxe was built in & sold in the market.

Awesome video. Thanks for sharing this

Very well made video and well explained. I have a dead socket 2011 motherboard, the cpufan spins up and nothing else happens. The motherboard was already dead when I got it. It is a Supermicro X9SRA and the bios chip is soldered on. I'm maybe thinking of replacing it and hope the motherboard will work again.

Hi, I have a h11dsi-nt, a dual epyc server motherboard and it stopped working all of a sudden, now when I power it on the fans start spinning but nothing on display, there is a green light that blinks after about 3 seconds , I de seated both cpus removed ram and ssd changed another power supply but nothing works what should be the issue here, thanks

man! you are an awesome teacher. you should be teaching university classes if not already. oth, just teach structured courses subscription based. i’ll pay. good job.

Just had a bad firmware update at work and remembered this video.

Thank you so much for this video!

i have a vert specyfic but stupid question is it possible to flash award bios chip with ami uefi rom from a different board if most basic components of the board are the same? i know in pentium 2 days i fixed multiple bios rot by simply booting the board from a prepared floppy with board specyfic rom , but it only worked if you flashed ami to ami or award to award, and i would like to flash something completly different to a board that wasn't designed for it tha thing however look a bit promissing because most of prewiously randm bits motherboard makers used like clock generators, memory and peryferial controllers all become integrated to 2-3 chips on the board . Main two being system controller and mainboard peryferial controller i am not sure how uefi woul react to different cpu voltage generator (different number of phases) but in the past i succesfully flashed oem bioses from different motherboards with the same basic components which didn't make problems of it (am2 fujitsu board with nvidia graphics to am2+ bios, but both boards were ami with the same flash size) i just would like to test the theory that it could potentially work with added uefi boot capabilities given that the donor uefi rom has it

Très bon vidéo. Merci

Can a motherboard be recovered from a point..if power button is placed cpu and atx fans even doesn't turn on

you just gave me some clue to figure out how to tell if my cpu is dying on my motherboard. the thing only post some of the time, but mdsched says the RAM checks out. so i'm going to remove the ram, plug a speaker in, and if if it consistently makes it to the RAM test phase, or fails before it gets there.

For curiosity - is there an issue with putting it directly on the carpet? We were always told to use a proper bench or at least put it on antistatic, wondering if thats true.

What does the recovery jumper next to the bios do?

@TheUbuntuGuy

4 жыл бұрын

It's for Intel ME. There is silkscreen for a "BIOS recovery" jumper, but that is not available on this HW revision of the board. Probably wouldn't work anyways, but if it was there I would have tried it.

pretty cool, I would've checked the communication between the chip and bios before trying to read the bios. You can at least see with the scope if there's something going on before going through all that work.

@TheUbuntuGuy

4 жыл бұрын

True. In my experience there is always some traffic if the board stays on like that. If you try to power this board with no BIOS chip at all, it will do absolutely nothing, not even turn the PSU on

In the pre-eufi time, i wrote "Bios-extract", part of coreboot, which mostly combines a bunch of existing codebases to an all-in one decompressor.

Very informative

Is it a wise idea to be trouble shooting that motherboard on carpet, because couldn't you kill components on it via ESD ?

Thank you for sharing sir new supporters here

So I have a a really high end motherboard with the hex codes and when I turn it on the codes do not show up at all. This video helped me out a lot but I cried yesterday when the codes were not showing up.

this video is a treasure

I love this shit. Please make more content like this!!

lol! nuce crotch rocket remark. Great video. I have a feeling that mine is a bios issue too but, my chip is a super tiny one that cannot be removed. Any advice? Anyone that does bios fixes?

Good job!

You brought back a person from grave. But have to see why the BIOS corruption problem occurred in first place.

hey you mentioned 1366 motherboards are usually bad, is there a common fault they all have? I'm stuck trying to get this 1366 motherboard working and it just shows no signs of life whatsoever, no fans or anything, it just doesn't do anything at all so if you could help me out I'd really appreciate it

Great vid, even with the lack of screen capture. A bios update, via UEFITool which I didnt know about before this vid, saved my motherboard also (Asus bios recovery sucks obviously).

For curiosity. After you pulled the raw BIOS/UEFI ROM out the capsule format. If it's supposed to be the same version, you can run SHA256SUM on the known good ROM. If different from what was pulled on the chip. You'd immediately know what was on the chip was wrong. As long as you have a good extraction, and the versions match. Most times you might not know/remember what BIOS version was on the board before it stopped working however. Great Video!

The SHA would almost certainly be different since the BIOS settings are stored in a filesystem within the flash. As soon as any setting is changed, the images will differ.

@smileymattj

Doesn't store those settings in a different ROM chip? It would seem if the BIOS settings are cleared when the CMOS battery is removed. And if the BIOS firmware were on the same chip, the BIOS would be vulnerable to corruption. Since volatile and nonvolatile ROMs are being stored on the same chip. I feel like it would be more reliable to store them separately in different chips. It could be possible that different boards are done differently; cost reasons, reliability, more secure, designer's choice etc... For example my Lenovo E32 board has a Winbond chip right next to the AMI-Aptio chip. I recall the Lenovo Thinkpad L430 having a similar winbond chip that stored the BIOS password. Could just be used for secure BIOS settings, I'm not totally sure. Since those aren't lost on a clear or CMOS battery removal.

very cool to watch this tutorial type of video for motherboard help :) new sub here :)

No. You wont have a chance the motherbard would survive that. The ram sockets VERY rarely fails. Instead your problem is most likely a bent or broken pin in the cpu socket, which is much more common after replacing the cpu.

29:40 also newer Board's powering the BIOS / UEFi flash IC with 1.8V. This could bring issues with a 3.3V Programmer.

One word ! Genius !

Did you try standard ecc ram before doing the bios? More then likely it was the registered/buffered ram you was using that was causing the problems (unless you could see the bios was actually damaged when connected to the pi) It supports ecc unregistered ram, trying to use ecc registered/buffered in most ATX server boards won't work (norm Basic xeons cpus) Rack Servers normally use registered/buffered ecc ram (there is a chip in the middle and most server ram can handle a double bit error and recover from it without having to do a crash the server workstion or low end servers use standard ecc ram (after the frequency of the ram > R, B, V ecc RDIMM won't work in basic server boards typically,, server/workstation boards use only UDIMM E type ecc)

Good morning, sorry to bother you, but I have seen that you are an electronics specialist and I was wondering if you could give me some solution. I have a Sindoh 3D 3DWOX 3D printer and when I inserted a USB flash drive to update the firmware, there was a power outage. Now only the Sindoh presentation screen is displayed and the image is frozen there. I have disconnected the printer from the power and even removed the internal battery from the motherboard but it remains the same. There is no way it does anything. It has been left frozen. I'm afraid the firmware has become corrupt. I have observed that the motherboard has some jumpers, I don't know if any of them have any use. Can you help me please? Any suggestions to force flashing the firmware? How can I find out which chip on the printer's motherboard is the EEPROM? Thank you very much in advance.

Thanks for tips.

Hello sir. Can i use arduino instead of raspberry pi.?

Thank you so much !!

you can rewrite a bios with a floppy disk or cd, without removing it from the board, it's called blind writing.....been doing it since 2002, works on all motherboards from 486 to present day, floppy disk, cd or usb stick with an ini file and basic dos, flash rom and flashing program for the rom file......will flash with a black screen. you do not need to take out the chip unless it is electrically faulty. there is no need for a blackberry pi

Yo we definitely are lucky. I also have a ocz psu in my test bench. It likes to ramp the fan full speed when using a older high power card like a xfx hd7990 but other then that was my first modular psu and was great up until the full bore fan point. Weirdly though I use this rig when buying used parts and the fan has never done it in there ever 12v rail is also dying but we’re running it until it dies completely

It's doable...however, obviously most home DIYfers don't have an oscilloscope or a raspberry. So not all is doable for us commoners. but man I did learn a lot. very cool vid

Couldn't these bios flash corruptions be due to cosmic rays? Btw well done, nice video

The BIOS chip was in a socket and you did not try deoxit first! Maybe you just scratched the oxide layer and it fixed itself.
