This is kind of embarrassing but I accidentally bricked my motherboard while flashing a bios update using AFUDOS. I didn’t have a backup at the time and was wondering if anybody has dumps of the two chips that are onboard. I was going to mod the bios but decided to just try updating the bios to the latest version first.
If not, I’d be willing to try to flash dumps of the foxconn quantumian-1 files which is the retail version of the board.
If anybody can help that would be great. Since it would be a shame to junk the board just because of a bad bios.
Could get the CH341 to show up in windows at all. Before flashing I did make a bios backup with AFUDOS and the file looked exactly like the bios flashed. No ME on it though. So I’m not sure if that’s why there’s a second chip on board.
I got an EZP2023+ to replace the CH341 but it won’t detect the chip properly. Found out it might be a 1.8v chip since it detected using the 1.8v adapter but not when my test clip was plugged directly into the flasher. But it’s not detecting as the correct chip.
From what I can read on the chip looks like a W25Q64DVSIG which I can’t find. Definitely isn’t a DW.
I attached the backup from AFUDOS not that it will be much help. I’ll try to see if I can get the flasher to read the chip though. Maybe a different test clip will work. X79_Bios_Backup.rar (1.8 MB)
Also want to say thank you for everyone trying to help. I really appreciate it
The other chip on the is a 25X40BVNIG. Not really sure what that one is for. Foxconn board reviews weren’t really sure what that was either. Maybe it’s where the ME is located?
I couldn’t read this one either but I think that came down to my clip not fitting the chip correctly. It’s not mentioned in the documentation from Foxconn either.
Dont tell me that you previously said the CH341A…because you didnt know the SPi Chip ID???
This is the 1rst thing to do…even without connecting the SPi programmer…
Now get info on those IDs pdf’s around the web and you’ll know the specs and voltage required.
Perform both dumps as they are now.
EDIT: Oh i see it was a defective hw piece.
With CMOS battery on or off, psu stand-by on or no psu attached…it cant have voltage fluctuations from/or without, for correct read/write, so thats a bit odd if its 2.7v to 3.6v operation range, on the ssheet.
Well a bunch of FFFF its a no go!
The W25X40BV its a 4M-bit/512K-byte (524,288), so it could be EC/Intel ME, same voltage operation range.
@stevogamer EDIT: Its my Mac Pro “half-brother” hehehe, its an unique machine and it has a nice chassis… for old timers like me of course…young people may say “arghhhh”
My CH341a doesn’t work at all. Got a defective one maybe. I’m now using an EZP2023+.
I did look at the chips beforehand. But not with the microscope. So I was manually setting in the programmer program to the correct chip ID.
When i saw the 25Q64CV I thought 3V (documentation says 3V). But it says not detected when fed 3V. Only detects a chip when fed 1.8V but when I actually try to read or write to the chip I get nothing. Can’t write properly (verification error) and read comes up blank.
Edit: Strange so everytime I read the 25X40 chip it has a difference read showing on the Hex values. Getting a no read anyways anyways. I think my clip doesn’t make good contact with that one. But yup a bunch of FFFF. Could be 25X40 just stores bios save data maybe.
Oh CMOS battery is in. No PSU power going in at the moment
Still haven’t gotten the alleged 25Q64CV to read though.Yeah it is strange. I don’t have any spare bios chips on hand at the moment but hopefully can get some in a few weeks. Maybe is a bad chip. Not sure. Since that winbond logo with the wrong font doesn’t give a lot of confidence.
I’ll see what I can do for the “fake” 25Q64CV but it doesn’t seem very promising so far. I tried 2 different clamps wasn’t having a lot of luck
