Hi guys!
First of all, nice forum! Lots of useful information. I am trying to revive a Lenovo E520 (1143-3KG) by replacing its BIOS as a first guess. I based this guess on information from Lenovo that lots of these E520s die from a faulty batch of EEPROMs used during production. Of course, I could have bought a new BIOS chip, but as a die-hard DIY nerd, I'm trying to create one myself using a MiniPro 866 USB programmer.
So far I have extracted the files from the Lenovo rom package .exe and decompressed the $0A8H000.FL1 file located in the folder named after the BIOS (see table below) and programmed the result on a new chip (same type as original). This doesn't work. So I have a few questions:
Please help me, I usually know my way around computers, but feeling very lost at the moment (as always when learning new tricks )!
Cheers
Rick

- Did someone write a manual for flashing bios chips?
- What am I doing wrong? Or am I doing it right and is something else broken on the laptop?
- What are the BIOS and Embedded controller parts? Do I need to combine them on the chip?
- Or does someone maybe have a working BIOS dump for this particular laptop (or know where to find it)?
Please help me, I usually know my way around computers, but feeling very lost at the moment (as always when learning new tricks )!
