Best Minipc Forum

I'm interested in downloading the BIOS for the GK2 model mini PC. I want to modify the microcode and customize the boot logo. Also want to see what I can unlock to possibly give the BIOS more functionality.

it is not possible to change the LOGO, if you have a large demand, you can contact ACEPC's sales customization

Not possible? Sorry, not buying it. I have modified many BIOS' on many different PC. Haven't ran into any yet where I couldn't modify the microcode. These mini PC are all based around the same design with the same BIOS from different manufacturers who simply stick their own logo into the microcode. It's very much possible, no question about it.

They tend to provide the BIOS only when there is genuine need for it. They also have the BIOS options limited in order to keep people from adjusting things that could cause problems.

You could try contacting after sales support at service@iacepc.com to see if they could provide it to you.

Preventing others from examining the BIOS and modifying it is just wrong. Many manufacturers rely on the help of end users to work out bugs and report bugs. Clearly anybody who knows how to modify microcode is not concerned about messing something up. Modifying a BIOS will of course void any warranty, but that's on the end user who chooses to do so. If I own it, I should be able to do what I like with it regardless of possible outcome. This is outlined in the "RIGHT TO REPAIR" legislation currently being brought up in many states. The BIOS file should be publicly available. Besides, all I want to do is just change the dang logo to a Pacman one for an arcade cabinet I'm building.

And as stated, you can contact after sales support to see if they'll provide it to you.

I learned about your professional ability through the video, and I will share your video with professionals in the factory. Do you have any requirements for BIOS?

No, I just need the stock one. I don't plan on doing any major modifications to it, just a logo swap for an arcade cab, but I would like to examine it for further information. Will also need to know which flash utility to use.

As far as I know, the BIOS file requires a special tool to open and change the LOGO in the BIOS. If you can change it yourself, you can contact the manufacturer to provide you with the Bios file.
