@StancuFlorin, not jet, it’s in progress.
I have bought a second MB, next step is to desolder the SPI Flash secure the bios as binary file for further Modificationen.
I will solder a DIP8 socket to the Mainboard to use 25QI28FVIQ Flash.
@MeatWar, I have read the Tutorials and learned that I have to export the actual Bios as Binary file, and that is my next step. I will not risc my working Machine so I’ve bought a spare MB, currently Im waiting for delivery…
Read was now successful, so I added the DIP8 Socket to the MB and testet the old chip, it still worked.
I Flased a new Winbond Dip Flash and it worked too.
Next update, i have enabled the “Admin” Part under Advanced in the Bios by switching to “Extended User” under Access/Use. It can be done for all subpoints that you want / need to access.
Now i can change PCIe Speed / With / … but there is no Point to change the Bifurcation setting like written in the examples.
Screenshots of the actual Bios “Setup Configuration”:
There exist Strings that discribe the usage of a Riser in the PEG Slot, but it seems not implemented in the Bios version. The Tokens cannot be found the Setup Configuration.
