please try this and report

Thanks! Finally I did not test it, since this dump does not cointains my motherboard specific data.

My final solution to repair bios and restore original motherboard specific data:

1. program bios chip with dump from post 249 -> bios does not contans machine specific data
2. after powering on the motherboard it gives some error messages like in post 250 about the missing data, however it is possible to launch Windows
3. when Windows is up, apply BIOS Configuration Utility from post 254 in the following way:
3.1 start CMD as admin and,
3.2 use BiosConfigUtility.exe /get:"actual.txt" command to write all available tokens / variable into actual.txt file
3.3 use BiosConfigUtility.exe /setvalue:"token from actual.txt","new value" command -> e.g. BiosConfigUtility.exe /setvalue:"SKU Number","G3K60EZ#AKC" will program G3K60EZ#AKC as SKU
3.4 repeat step 3.3 until you set all required tokens.
In my case theese were: Product Name, SKU Number, (ENTER) Feature Byte, (ENTER) Build ID, Serial Number, Product Family, System Board CT
3.5 when finished use BiosConfigUtility.exe /setvalue:"Manufacturing Programming Mode","Lock" to lock your bios
4. shut down Windows
5. power up your machine and it should start without any warning


Thanks everyone for your help!

Hello,
Need compleet new bios file for this laptop.
Have new chip purchased and will use CH341 programmer
Old bios data is not available.
I have read that a serial number must be entered in the new BIOS.
Read a lot but it is not completely clear to me with Google translate.
How can I best approach this?

Thanks,
Marcel from the Netherlands
