Hi

@johnvick - Thanks to @MiesMosel see chip ID to use here in his post - [Guide] Using CH341A-based programmer to flash SPI EEPROM (24)

Here is latest version (1.41) of ASProgrammer - https://github.com/nofeletru/UsbAsp-flash/releases/

Hi all, I have a concern for this case : a board has main IC and flash IC, the tester only writes program/data into main IC but is there any case that flash IC also have program/data? ALthough it is just an memory IC.
Thanks.

@huyho - Some systems have two BIOS/Rom IC's (all flash rom), in those cases yes, often smaller chip contains EC FW, or FD+ME or FD+ME+Partial split of BIOS region with rest on main larger chip
90% of motherboards (desktop) have only a single BIOS chip. If you want more specific answers it would help if you mentioned the motherboard or model name/ID etc.

@Lost_N_BIOS, very appreciate for your support!
The board I have mentioned not kind of motherboard, I work in SMD field so the board we called it PCBA. I wonder if you know or not but thank you again.

@huyho - I know PCBA, but yes, assumed you meant motherboard If you are making the items, you control what flash store-able IC's are on there, so unsure what your question means.

Hello to all. before doing any damage, I would like to ask you how to remove this chip https://imgur.com/TSnfiXi in complete safety to avoid damaging it. What should I pay particular attention to?

@nicovon - You need to use correct chip ID as mentioned in PM. I found proper BIOS from your link above now, it's a 8MB chip, so you will use some chip ID that has 64 in the ID
Best you dumped your BIOS chip before you did anything, did you do that? If yes, send me the dump, I will make you BIOS to use in programmer, that way you wont loose your serial, UUID, and LAN MAC ID

@nicovon - If you did that, then it's wrong, unless you put in the wrong chip maybe? Does that board have more than one chip in a socket? I know some boards have an audio chip in socket
What version software are you using? And, what is your actual chip ID, look on the chip itself, use magnifying glass and flashlight if you need to.

If that is your actual BIOS chip, and you dumped it before you erased or wrote to it, then good! Yes, send me that. If you dumped it later, send me that too anyway so I can check if anything salvageable left on there.
With that ID selected, it may only dump 128KB anyway, if this is the case, don't send to me, no need for me to check that.

@nicovon - See, that is "64" in chip ID, this chip not what you originally had shown in image (Winbond 128KB ID), this is Gigadvice GD25B64
Use Software 1.30 or 1.34 (or asprogrammer 1.41), and chip ID GD25Q64 (Q/B = Same 3V, 4KB Sectors & Quad I/O). Select that ID manually, if "Detect" is failing

Here is general software package if you do not have 1.30 or 1.34 - http://s000.tinyupload.com/index.php?fil...695330485827902
And here you can get ASProgrammer 1.41 - https://github.com/nofeletru/UsbAsp-flash/releases/

Chip may be still OK, contain some data, if you only wrote 128KB (this dump is 128KB beginning of BIOS file). Dump chip using above info and then send to me, do not erase or write anything to it until I say to go ahead
