Re: CH341a programmer
Winbond W25X20CLNIG IC Chip
AMI MSI BIOS For Z490 WiFi Edge
Hey all, I'm trying to learn how to fix bricked or semi bricked motherboards that I've collected through the years. I managed to reflash and fix an MSI Z170 and a Gigabyte AB350 and also an old Asus Z87 Pro WiFi board that I had to use the UEFITool to convert the CAPCOM file but this MSI bios is not CAPCOM so that doesn't work.
I hit a snag using the CH341a software and am getting "IC too small for file" error.
The ASPROGRAMMER software was able to read the old bios in 2 seconds and it is 256kb in size? Thought that was rather strange as the other boards chips took much longer to read.
So, I downloaded latest BIOS file from MSI for the Z490 and extracted the BIOS from the zip file. It is a E7C79IMS.1EO file, and loaded into the program, it is 32MB in size, but the Winbond W25X20CLNIG IC is apparently too small in capacity. According to the data sheet The Winbond W25X20CLNIG chip is "2M-BIT with 4KB sectors".
Now I am not experienced in this but out of frustration and just for shoots, I tried using the UEFITool and opened the bios image file in Hex view and searched for a BIOS section.
I found it and selected it and saved it " as is" but that's 16MB in size and still is too big for IC chip. Probably wouldn't have worked anyway. Seems like the bios file is heavily compressed?
I have searched online and youtube and read you can modify and trim a BIOS file with a hex editor but I can't find any instructions on specifically how or what to look for, cut, remove, save, convert etc.
It was mentioned regarding removing a Header and a Tail from BIOS file so it fits into IC chip. Sounds like it's not an easy thing to slice and dice a BIOS for untrained folks like myself but I don't mind reading and taking the time to learn.
Also I should mention that I have the exact same board running in my main PC and was wondering if I could use the programmer to read and save its BIOS file and maybe transfer it over to the bricked board?
Any helpful directions or pointing me in the correct path is greatly appreciated.
