HI, I know this might be a noob question but Im trying to setup for flashing different kind of rom files and I need to purchase the hardware to do so. I am looking to flashing motherboards and other rom devices. Can you please guide me into buying the proper hardware or if you sell it I would gladly buy it from you. Thank you.

Hello Ray, The hardware that you would need is something called a BIOS programmer. Usually they use a USB port and might be found cheaply online. Flashrom has a list of supported programmers: https://www.flashrom.org/Supported_hardware#External_flashers.2Fprogrammers My suggestion would be to purchase a Raspberry Pi, which is a cheap Linux computer that has builtin hardware support needed to flash ROMs. It might be less trouble and more easier to get. The Pi, microSD card, case, breadboard jumper cables and breadboard (for easier seating of BIOS chip) may cost around $50 USD. On 2019-10-05 2:40 p.m., ray@ineedageek.us wrote:

The Raspberry Pi certainly makes a nice, fast flasher, however the IO pins are connected to 3.3V rails so you'll need to be careful to use it with 3.3V flash chips only (not 1.8V).

I didn't know that there are chips that use 1.8 volts, I don't know much about electric devices, but could you just connect a resistor or something to reduce the voltage?

One of the good things about the RPi is that it is popular. You should be able to find answers to your issues without too much difficulty. I *highly* recommend that when using any cheap SBC as a flashing device that you power it from the mains electricity. This means a transformer that plugs into the wall and gives 5V on the other side. Trying to power it using the "5V" that a USB cable carries from the USB port on a computer is not as reliable. Aside from necessities such as SD cards to carry the OS, try to minimize the amount of peripherals attached to the SBC. This will increase the power available for the flashing process.

This is the first I've heard of this too. If anybody has any examples I would be greatly appreciative. Andrew -- OpenPGP key: EB28 0338 28B7 19DA DAB0 B193 D21D 996E 883B E5B9

See https://ao2.it/111 The interesting bits are from "In order to flash at 1.8V [...]".

I'm going to be doing to BIOS work with a high risk of bricking the device I am working on. In the end I decided to grab one of the cheap CH341A programmers of eBay, partly because the various tutorial videos on YouTube were confidence inspiring and partly because it looked much easier to set up physically then doing a bunch of work with hook up wire. I can't offer any real world experience about its performance at this stage since I'm still waiting for the brickable device to arrive but, as I said, the YouTube tutorials were useful here. Daniel.
