There are many different SPI programmers on the market right now and almost any microcontroller-based board can be used as one, but this time I will speak about one of the cheapest programmers to date - CH341A-based. They are sold from various chinese suppliers for about 4 euro and are capable of flashing with both SPI and I2C chips, working as USB-TTL adapter and USB-I2C bridge. In this guide I will only cover the SPI part of functionality because this is what you need to flash modified or res…
If you’re worried about flashing your motherboard with an SPI Programmer, then this is the guide for you. Each step is explained in detail, with pictures. We’ll go over everything, from buying your Programmer to flashing your chip with Flashrom. As per usual, this is a tutorial on the internet. Do anything you see here at your own risk. I am not responsible if anything goes wrong. This tutorial couldn’t have been possible without: Fernando, for the Win-Raid Forum, ProIIIu3Hb, for their PIII D…
I’d recommend using the flasher- if you really want to proceed, it might be difficult to bridge the ME pads and the result is doubtful.
Read the chip, you need at least two dumps which are 100% identical and have a proper firmware structure in UEFIToolNE. Attach the dumps to your next post.
