I'm sorry i'm going to explain myself.
I have a Beelink U55 that is now bricked after a bios update (which someone else did).
Reading a little bit more i discovered that this update was for the EC (that is the 1mbit chip i was referring to) and i managed to find the correct EC .bin on the beelink website and flash it. (It would still be useful to compare the two if you can get a dump of yours, i managed to do it without dissoldering it and connecting with the SOP8 claws). I will PM you with the link.
My minipc is still bricked tho, i will look into the Q64CWIG (big chip) in the...

I have the same problem but my lack of experience can't tell which one is the bios chip between the two, what about the little sop8 chip next to it (gd25d10ctigr 1mbit SPI flash)? Can you provide a dump of that one?
