This graph shows how to wire your Arduino Uno to your 3,3V BIOS CMOS Chip: The three voltage dividers for CS, SI and SCLK Affected by this alteration are the CS (Chip Select), SI (Serial Input) and SCLK (Serial Clock) Pins. Anything above this rating is definitely not healthy for this chip.Ī simple voltage divider on a breadboard is just right to adjust the 5V from the Arduino to appropiate 3,3V for the BIOS chip. The MX25L8005 used in my case for example, is able to handle 2,7V up to 3,6V. Please refer to the datasheet of your BIOS CMOS Chip for a voltage rating. In the most cases the Arduino Uno logic levels are 0V and 5V respectively, which is too high for most BIOS Chips. Now we have to be extra careful not to destroy the BIOS Chip completely by applying a wrong voltage to it. Getting frser-duino ready Step 6 – Wire up the Arduino to the BIOS Chip Step 3 – Get the necessary PackagesĬonsidering that we’re running on Debian, please make sure your system is up to date and has the following packages installed to prepare the flashing environment, demanded by FlashROM and the Arduino flasher frser-duino we’re going to use later.
Spi programmer msi iso#
Yet I was able to find a suitable ISO file, whose unpacking lead to a IMG file, whose unpacking again lead to a FreeDOS environment, containing the long searched BIOS image file named “A7504NF1.10Z”. In my case I had to search a little longer, considering finding a BIOS download page for the (now) 13 year old MSI MS-7504 was quite more difficult that I initially thought. A simple search with your mainboards model number will guide you there. However in most cases the mainboard manufacturers are offering BIOS Images on their websites to be downloaded (mostly in the Driver/Support sections). This step is highly individual and can differ immensely from case to case. In this guide we’ll be using a MX25L8005 CMOS IC by Macronix. Please note, that on some mainboards, you first have to remove a sticker from the top of the BIOS Chip to read off the type number.
Basically find the BIOS chip on your mainboard and read off the type number on it. Since we are going to use the FlashROM Flasher Program, please make sure that your BIOS Chip is listed in the compatibility list of FlashROM. So this guide will show you, how to flash your BIOS Chip via USB with an Arduino Uno. It turned out that the cause of the problem was indeed the BIOS. After some troubleshooting, it pointed more and more it the direction of a faulty CMOS Chip. Recently I’ve got an old computer for free, with the downside however that it wasen’t posting.
