They certainly know stuff that I didn’t know I didn’t know. I've complimented your approach and how addictive this channel is a couple of times, but you also have amazing subscribers. In the comments there’s a wealth of information and very little ego. They are people who seem to genuinely want to share information.

[@VndNvwYvvSvv]

Low voltage, yes. Compatibility between slots/board and the memory cards can be either direction, both ways, or neither, but without knowing ahead of time, just uses what's spec'd.

[@mickywoods]

Amazing stuff - well above my head but great to watch how you work

[@sp_charles24]

Ultimate tutorial about flashing BIOS file and editing it with the old ones, which is precious. You just shared it with us free of charge. Hats off. Now have a little deep understanding of the importance of BIOS.

[@victorzedwings]

Absolutely! But sometimes EC firmware mismatch may play a bad joke, till you sync it with the BIOS version.

[@warenmann1042]

Excellent video, I like the direction you are going in your repairs. Thank You...

[@nickdatyner1519]

This video was incredibly useful. I had a Lenovo Yoga S1 (LA-341P Rev 1.O mb) which only started fan briefly and blinked keyboard background LED. I'd removed BIOS chips and read them and compared to ones I had downloaded. Based on your comments it looked like the downloaded ones hadn't been initialized. Decided to reprogram using a CH-341A programmer. Used Neoprogrammer software since AsProgrammer version wouldn't program reliably. So programmed and soldered the two BIOS chips U8, U2202 and bingo started up . Had wondered about the KB9012 Super IO being bad but was the BIOS. Also everything seem fine so maybe other info like serial number etc is stored somewhere else on this machine. It is from 2013. Thanks!

[@DanielsGameVault]

A tip I have when doing BIOS "rework" is to leave the original chip as is and always have some new, blank chips on hand and mess with THOSE instead. That way, you're sure it's not the chip itself that's faulty by having some bad blocks or other sh!t like that - highly unlikely, but still. As long as there's that 0.01% chance that there IS something wrong with it, you've covered that possibility too. EDIT: I think the KBC in this case is the ENE chip itself. You can tell if you see the traces from the keyboard connector going to it and I know I also read somewhere that it IS possible through some freak adapters and procedures to actually flash this ENE through the goddamn keyboard flex connector :)))

[@funhaveatutti]

The RTC Reset work if you power cycle the laptop after soldering a bridge, that reset is more in deep than disconnect the bios battery, that clean also any bios password (sorry for my bad English)

[@SiETechNotebookReparatur]

BIOS works are one of my favorite works, have also often shown in videos. I am often asked to make a video about BIOS repair, but it is not feasible to make such a video that could generally show how to repair BIOS firmware. It is only practical examples that can be shared and with new generations come new problems and knowledge. There are also differences between Intel and AMD (AMD has eg. no Intel ME) With experience it gets easier and easier, you understand the logic behind it, but handing over the whole thing would be extremely difficult. Practice makes the master :)

[@ErickBuildsStuff]

@SiE-Tech Notebook Reparatur, I think I will drop an email to you tomorrow. I would like to get my ASUS laptop repaired. It has the same issue after a failed windows update that also brought with it a bios update. That bricked my laptop in a single day.

[@markanderson2904]

Agreed. It seems that if one new how to write a BIOS and could decode the "program" in the BIOS, one might be able to discover all those things.

[@mikewarnes9830]

Love it, great information and entertaining too thanks

[@MarkusHobelsberger]

One thing you should also point out is security. A random bios file from the internet could very well contain malicious code or some kind of rootkit. It's not very likely but you never know.

[@soorajsprakash9405]

what malicious activity it can cause??

[@christopherjackson2157]

Definitely a possibility. Tho it's hard to imagine that being a productive use of someone's time. Especially someone with that degree of technical skill and knowledge. Still can't be ruled out. Ur right it should at least be mentioned.

[@spottedtango]

it's possible. Is it a likely occurrence or even a likely vector? no. The technical skill to build an effective rootkit that can live in 4MB or even 6MB that can interface in the way it needs to without disturbing/breaking the original functionality is a tough ask, not impossible, but nor easy. Also you have to consider that there isn't a whole lot of incentive to use something that specifically targeting and sophisticated on public forums. People making bios level hacks are doing to to target a government issued model for international espionage, not to steal grammy's recipes.

[@nyanpasu64]

There have been UEFI rootkits discovered in the wild, such as CosmicStrand.

[@FR4M3Sharma]

Love the way he explains every tid-bit, my only gripe is that the video becomes too long even though I watch him on 2x.

[@Adamant_IT]

In retrospect I should've split this one. The first half is basic No POST stuff for repair-beginners, and the second half is mid-tier BIOS reprogramming. Two very different levels of repair.

[@adammesic]

And I thought I knew about computer building and repairing. I know s***t! This is just a next level. You sir have "passed the game".

[@graphicsgod]

Exactly! I'm used to finding a bad fuse or resistor or chip and just replacing. Never thought the BIOS would go bad (corrupted) and cause the laptop to not start! I usually just check things with a multimeter, and go from there. 🤷‍♂️🤷‍♂️🤦🤦

[@mulatiechekol4513]

Best explanation!

[@kztech1319]

I do think that you need to flash both chips at once if you are gonna do a BIOS reflash. If your BIOS dump is a different version than your current corrupted one, flashing one chip may not work, and that's probably what happened. I have a conductive ink pen that I can simply draw traces if I want to temporarily connect something. The ink comes off immediately once you apply alcohol to rub it (Apply clear coat on top if you want it to be permenant). That said, those pens really like to jam over time and both of my pens have jammed already, so I have to take open the pens and apply the ink with a small screwdriver, but whatever For 24:27 , in my experience it definitely helps to apply flux if you are removing things with a large surface area with a soldering iron, it helps more evenly distribute the heat of the soldering iron and you can much easier use a flat blade tip to remove all 4 pins at once and lift the BIOS chip up on one side for instance.

[@maximumofname]

You can start a cmd window directly in that folder by simply writing cmd into the location bar of the explorer window

[@Adamant_IT]

Even faster, if you hold shift or control (I forgot) and right click, new option will appear saying to open the location in CMD or PowerShell.

This video seriously makes me long for the bygone era, when bios's were socketed and swapping them out took moment. Flash it wrong, no problem, a supply of generic chips and away you went. Excellent video though

[@iTCXtreme]

ME Region is within the main bios and it only on Intel platforms logic board/cpu. The 2nd bios is EC or Recovery. Some business edition laptop such as Fugitsu has 2 bios ic, main (8mb) and ec (1mb). Some boards EC bios is within ENE, ITE controller, which requires programming via keyboard connector. As always a great video 👍. Take care 🙂.

i`m in a similar roll but i just hate trashing motherboards over what might be a 1.40 in parts and a little know how.

[@stevedebeukelaer1424]

Hi Graham the kbc is the firmware inside the ENE chip which can also be corrupt, that you must flash through the keyboard connect. Your rtf809 programmer is possible to do that but you need to loook up the correspondented connection on ene chip with wires or keyboard flex., the other one is chipset firmware which is intel me firmware. Also when you make a dump you need also make at least 2 dumps and compare the 2 with hxd editor. Just tips i give. Nice tutorial. To fix the dump it can be the problem with me region firmware otherwise you can fix the bios dump otherwise through replace the me region from the dump and clean me after. For bios is one guy who knows a lot of bios problem who has a youtube channel with Name ERRA the guy is also active on ERS discord. He is fantastic technician. This just to info. You will learn a lot from him abouth bios. This is his channel kzbin.info/door/jnbxkuatqFUOka45PbTQvg Regards Steve From Belgium

[@mattmaks]

You don't need to compare 2 dumps with HxD. You can use tool like md5sum file.img (in linux) or C:\>certUtil -hashfile C:\file.img SHA256 (in Windows) and compare only the checksums of two files. If the checksum is the same than we can be almost certainly sure that files are the same. One more thing: Windows key is stored inside so called SLIC table. You can even add it to the bios which do not have it (if you know what I mean ;)

[@Lardzor]

When first I read the title, I thought the power supply was outputting 350v. No Post would be no surprise.

[@nticompass]

Have you looked into using an "alternative BIOS" like coreboot? I don't know this laptop is supported by coreboot, but it would be neat to see a video about that. I have a ThinkPad T430 that I flashed with coreboot. You can use me_cleaner to sort of remove the Intel ME, or you need to dump your original BIOS and inject the ME region into the coreboot ROM.

That was very instructive. The BIOS modding part was interesting, I loved it ! I used to flash BIOS via a ch341 (old version, the new 1.7 version is on his way, thanks to your previous video), I already known the procedure to get the windows product key (it's pretty standard, address 006CD00 in any single bios bin file via an hex editor) but I didn't paid attention to MAC address or s/n.

[@AnonymousRepair]

Nice Video, The only thing is that using extremal display doesn't always work, Most of the newer laptops will not give you an output to external display from the bios, I stopped using that option long time ago, Now that there is no more caps lock lights or num lock lights on the internal keyboard from laptops I just use external usb keyboard to test if num lock or caps lock works. other good one that works well is ctrl+alt+del you should be able to detect the reboot .👍

[@David_Ladd]

Great video & Thank You for sharing! I didn't know about these tools, but thankfully I haven't run into any modern PC's with BIOS problems yet. Thankfully most of the computers I work with are much older. Like PC motherboards that are old enough to still be using Winbond 27C512 parallel style (E)EPROMs. Oh fixing blown 2364 style ROM chips from Commodore 64's, Tandy Radio Shack Colo(u)r Computers, Dragon 32s, Dragon 64s, and Dragon Tano(US version). A lot of the tips and tricks you used here for merging the BIOS files from the two flash chips are common tricks to combine M$ Color Basic and M$ Extended Color Basic together to burn in a new combined (E)EPROM on a TRS Color Computer. I can't wait for more trips and tricks and walkthroughs for people to understand extracting and repairing BIOS data from the UEFI sections of modern BIOS images.

There is nothing in the world but 2 things, which makes a man change his rigid face for a smile: one is when working in a dead laptop and suddenly shows BIOS screen; and the other one is from the watchmaker when mounts the watch and the scapement wheel begins to move regularly.

Theres a clip type adapter to program the bios chip, you can attach it directly to the bios chip without removing it from the board and flash, saves lot of time and effort.

[@SimonQuigley]

There is, and I have one of those, but it's horribly unreliable, and I have given up after 20 attempts of fiddling with the clip and just desoldered it, and it works first time

[@nyanpasu64]

I'm wondering if today you could use a Pi Pico as a SPI BIOS flasher (or anything else you want it to be), for a price similar to a CH341A and cheaper than a RT809F. Last year I went through recovering a Dell BIOS which had slowly developed corruption preventing it from booting (and broke a chip leg and ripped a trace trying to attach probe wires to the motherboard in-circuit since I didn't have hot air), but didn't restore the old data partitions. I didn't know that there was an old and new version of UEFITool and that you could replace the NVRAM data partitions on a chip, thank you for telling me that!

[@reecebower9934]

I really like that when you don't know something your not afraid to say so. A lot of youtubers try to act like they know everything.

[@RSTVlog87]

those BIOS chip actually using i2c interface (sda, scl). you can read write without desoldering using arduino or raspberry pi (connect cable to sda scl gnd pins). if the chip doesn't get stand by power just inject bios vcc pin with bench psu, some board need grounding master oscillator to prevent other component from running but keep stand by power.

MAC addresses identify the vendor. That’s one way you can validate the NIC MAC. Imagine if you screwed that up and ended up with a MAC of FF:FF:FF:FF:FF:FF! Fun times!

[@erra4electronics]

Hi, why not just checking the serial number in the laptop case and use it as a keyboard to search for it in the bios file in any hex editor and then copy the corresponding hex value of it which you can also use as another keyword of search in UEFITool to locate where it's stored without loosing much time in trying to search it manually. That also avoids you to just guess where it can be stored, and it should be showed in bios settings if transfer has been done correctly. check the schematic it has a lot to teach about bios chips :wink: : 2MB chip: drive.google.com/file/d/14SThD8j56iZKVz9iHb7Ucz-HElcXIhNk/view?usp=sharing 4MB chip : drive.google.com/file/d/18VdvYz-tCEpM2w36LJ2rH1QBIfC5oDvN/view?usp=sharing Schematic: drive.google.com/file/d/19NxNODhrML4u3ig8bZWGi15et42vTkke/view?usp=sharing
