So I've got this HP-15b018CA motherboard that I grabbed a BIOS dump from. While I was troubleshooting the board, the KBC (ENE KB9028G) let the smoke out. I'm able to get another KBC, but I have no programmer for it. Is this one of those KBC that will be programmed from the BIOS chip (I've read that certain KBC will take the programming from the BIOS)? How could I tell from looking through the BIOS bump if that is the case with this chip?

Re: Bios dump include the KBC?
If you would have posted your dump here,then it could be stated with certainity that your dump has kbc bios in it or not. usually, the main 8mb dump has kbc dump. Your another query-whether it will program automatically or not(as long as new kbc is blank) cannot be confirmed as i never replaced kbc on this board. On some hp it does program automatically but in most of the cases it doesnt program automatically and you need a kbc programmer to do the job. So no concrete answer from me. -
Re: Bios dump include the KBC?
OK here is the dump. If you could take a look and see if the KBC is in it that would be great. But for future learning, what is it you are looking for that would indicate that? I'm familiar with using a HEX editor, or is there some other piece of software that works better?Comment

Re: Bios dump include the KBC?
EC content begins at 20 0000 in this dump.
Search for string "ene" or "ite" depending on the ec type.
As i see you have already changed the win key to xxxx -s, that's a good practice.
Another way is to unpack official bios update with phoenixtool and look for appropriate size module in the list of modules.Comment

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.

Hi,
I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.
It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.
I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...11-06-2022, 05:22 PM -
Hi everyone,
I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.
I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...
