    Hi!
    Just wanted to check if you're still able to help with unlocking bios, before I purchase a reader/writer.

    Sweet! I'll buy myself a reader/writer, then I'll get back to you!
    Any suggestions, or would any CH341A reader work?
    I was looking at this one: https://snipboard.io/th2Lub.jpg
    I haven't done this before.
