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 :)

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 :)))

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.

SuperIO actually specifically (at least nowdays) refers to a chip providing serial and parallel IO. I know in past times they generally handled more or the chip that does handle parallel and serial handled other stuff on older boards.

The 'KBC' file is for the superIO chip (the ene chip) its actually a full microcontroller with its own flash on board based on an 8051, you can program it with a standard ch341a by soldering a few wires to the keyboard connector it is the keyboard layout but is also the complete firmware that controls all the ancillaries such as the power button, LEDs and fans.

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!

I would say that flux will help in the removal of s.m. components. The solder melting point is slightly lowered by adding flux, or should I say the temperature at which the solder becomes fluid is lowered. Why wouldn't it help? De-soldering is just the reverse of soldering after all. Edit: Very interesting to see how you combined the files on the command prompt with the binary switch and then how you split them apart using a hex editor. Great video.
@radio-ged4626 Жыл бұрын
@Damion Manuel Hi, of course you're right. It only lowers the effective melting point because you don't need as much heat when the oxidisation is removed. The melting point of the solder always remains the same in a given atmospheric pressure if it is not chemically altered. Full pedant marks to you. A gold star is in the post. :)

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.
