BIOS Programmer on B350
BIOS Programmer on B350
Hello, I own an MSI Mortar Arctic B350M that I purchased used a few years ago. The seller had a BIOS password that I haven’t managed to remove. I’ve reset the CMOS jumper, removed the battery and powered down for 24 hours, etc. I’m currently running it with an R6 1600 and want to upgrade to an R6 3600, but the BIOS isn’t current. My last option has been using a BIOS programmer, particularly the CH341A with an 1.8V adapter. My goal is to read the BIOS contents to locate or modify the password. If that’s not possible, I’m hoping to flash it through the programmer so the password can be cleared or updated, allowing a smooth upgrade to the newer board and ensuring the final BIOS version stays intact. The main challenge is figuring out how to operate the programmer with the 1.8V adapter and locating a version that supports this chip on the B350. There are many guides on using the programmer alone, but none addressing compatibility with a more recent chipset. I’ve identified the BIOS chip as: MX25U12873F (https://www.macronix.com/Lists/Datasheet...X25U12873F, 1.8V, 128MB, v1.2.pdf). According to the docs, the 1.8V adapter should work, but it’s not visible in the software. Any advice would be invaluable. Thanks!
this process involves removing the existing BIOS, installing the new one, and then flashing it. make sure you're using the correct motherboard image if needed. for socketed chips, replace and reinstall carefully. i don’t recall any tools that can read BIOS passwords, and i’m not aware of legal ways to access them.
You can link the programmer to your BIOS chip directly using a SOIC-clip or an SPI-cable, or connect it to a JSPI-header on the motherboard. The parts mentioned in this post are for other uses as well.
