Review: Works Great for Programming BIOS - I'm new to BIOS programming, but after understanding it's quirks, this is quite a powerful tool! My chip was from an HP ProBook 640 G3 and is held in place with a spring retainer mechanism; therefore, programming is done out of circuit. The spring clip of this device _must_ make solid contact, even at the risk of crumpling the pins. Just flatten them out later like I did. If using IMSProg like me, the telltale sign of a bad connection is that erasing only takes a few seconds. With a solid connection, it should take closer to a minute. The programmer works well and is a very inexpensive alternative to raspberry pi and whatnot. If you have a locked BIOS and need to get by the forgotten/unknown password, this is your oyster.

Review: I love this tool - Love this little tool. Wish I had more excuses to use it. A friend locked themselves out of their laptop by setting a BIOS password that they couldn't remember. I cleared the CMOS memory several times, but the password persisted. I did some research and learned that modern laptops don't store BIOS passwords in CMOS. Instead, they are stored in non-volatile memory, such as the eeprom on the BIOS chip itself. Further research indicated that this particular laptop likely used an AMI BIOS implementation, and that the password could likely be decrypted or cleared. I happened to have this tool on hand and was itching for a reason to use it. I had never used a BIOS programmer before, so I read a few guides, identified the BIOS chip, and downloaded and reviewed its datasheet. I booted Ubuntu on another laptop and installed flashrom. I verified that flashrom was compatible with the BIOS chip. I hooked up the clip, and flashrom recognized the chip on the first attempt. I dumped the ROM three times and confirmed the checksums for each dump matched. I used UEFITool and confirmed that I was looking at an AMI BIOS and that the AMITSESetup variable was present. I found a tool on GitHub named AMITSESetup Decryptor & Unlocker that was unable to decrypt the password, but it did clear the password from the ROM dump. I flashed the modified ROM back to the BIOS chip, and much to my surprise I was able to boot the computer with no issues and no BIOS password prompt!

## Features

- The SOP8 clip enables in-circuit programming of without disassembling the chip, making flashing the BIOS simpler and more efficient.
- The main purpose of the CH341A Programmer is to back up, erase, program, calibrate and other actions on various software.
- The CH341A programmer supports most of the 24/25 series SOP8 chips on the market, but not all of them. Please be sure to check whether your chip model is within the compatible range in the product description before purchasing.
- The SOP8 clip support both wide body and narrow body SOP8 chip with 1.27MM Pitch.
- We provide detailed PDF tutorials, CH341A software, and drivers, which will be sent to you by email after the order. If you do not receive it, please send us a message.

## Questions & Answers

**Q: is this model compatible with a winbond 25q64fvsiq chip?**
A: Were you successful?  I have the same chip and have not been able to detect it or read it.

**Q: Can this be used to flash pic/avc/picaxe chips?**
A: No, it's for SOP8 EEPROM chip

**Q: Is it possible to use this flasher in Command Line Inteface?**
A: Yes.

**Q: Does this work on macos? what software should i use?**
A: This is a windows based program, most of the time a chip cannot be read without removing it. The clip doesn’t fit a standard 8 legged bios chip either.

### ⭐⭐⭐⭐ Allowed me to downgrade BIOS on my ASRock X370 Taichi motherboard
*by J***E on January 7, 2020*

I upgraded the BIOS on my ASRock X370 Taichi motherboard, ignoring the warning on the download site that downgrading wasn't possible. Then I found myself wanting to downgrade it. Oops. Fortunately I was able to learn online that I could probably downgrade it with one of these CH341a programmers. I know nothing about these EEPROMs and stuff, but I managed to do it, so I'll share how in case this helps anyone. I created a Ubuntu USB stick and booted another computer with it to run this programmer. The YouTube video I found on using this said the second LED on this programmer will light up when you have a good connection to the chip, but I couldn't get it, and when I'd try to run the Linux 'flashrom' program to read the chip, it said no chip found. Then I read one reviewer that said this chip clip is junk, so I bought a blue Pomona one that was supposed to be better and soldered it to the wires from this one. That one IS a better clip, but in retrospect I believe the one included with this kit would've been adequate for me since the problem turned out to not be the clip. I noticed that when I had the clip on the chip solidly, some LEDs on my motherboard that are usually blue when the computer is on would light up a very dim green, but flashrom still didn't see the chip. If I turned the clip around 180 degrees, I'd get no light from those LED's but flashrom would now say "unknown chip", which really threw me since it made me think it was now seeing the chip and just didn't recognize that model chip. Turned out the orientation the lit those onboard LED's a little was the right one. I couldn't read the writing on top my chip, so I couldn't Google for its model # to find its voltage. I assumed 3.3V, but ended up changing the jumper to 5V also, with no luck either way. Later I learned that the chip was probably 1.8V and Amazon sells voltage converters for use with this programmer for that. But before I bought one of those, I decided I'd try something that was probably stupid. I just turned my PC on with the clip clamped onto the chip, figuring it would supply 1.8V. To my amazement, it worked! For the first time, flashrom was able to identify my chip as a MX25U11283SF, which I then Google'd and found is in fact a 1.8V chip. So I'm not sure how I didn't kill it with the 3.3V and 5V, but I was finally able to program an older version of the BIOS downloaded from ASRock's site, and the computer has been working fine since. By the way, the second LED on the programmer only came on during read/write activity for me. P.S. one of the product photos tells you to make sure to connect to pin 1 on your chip correctly, yet in the photo pin 1 on the cable going into the programmer is backward from how it should be! Look at the diagram on the programmer to find its pin 1.
