Re: Buffer size not equal to IC size

Re: Buffer size not equal to IC size

I soldered the chip on the adapter board, and i selected the chip manually.
The chip is 10MB in every single software i tried even without the programmer pluged, so it's not the software and probably not the chip
I just don't understand how the reading was 16 if the chip is 10.

and what in the name of god is the actual bios chip?

I have the same problem.. I'm trying to bring to life a dead lenovo yoga S740 with the ch341a programmer! the problem is, the bios chip is a 8mb chip(GD25Q80CSIG) but all over the internet I only find 16mb bios file..what the heck!!?? motherboard number: NM-C451

The chip is 8M-bit ,8 mega bits . 8M-bit = 1MB .You have found the wrong chip. A 16MB bios will be a 128M-bit chip. 128M-bit / 16M-byte

Is the 16mb chip smaller than the 8mb? I can't find it..

In physical size no. Its a WSON8 chip. Don`t try and use a SOP8 clip to read it . I suggest you do some reading first before you do anything else https://www.badcaps.net/forum/showthread.php?t=103526
