Hello!

This hardware solution for autostart:

Hello everyone. I also want to change this behavior. I'm surprised why they didn't use a switch instead of a press button.

Anyway, anyone had luck with changing the BIOS yet?

Hello,

As I see it there are two possible solutions:

1. Modify Bios.

I downloaded the bios source from the Gizmosphere web site only to find that it is for the original Gizmo not the Gizmo2. I eventually got the sources from Sage Electronic Engineering LLC and have been looking into mods.

One problem there is updating the bios flash if you don't have an SPI programmer. You can do it from the Gizmo2 itself but if the new bios has a problem and doesn't boot then you will need an external programmer. It should be possible to use something like a raspberrypi to do this. I haven't yet been able to take this any further.

2. Additional circuit.

Build a small reset circuit to pulse low the power signal after a short power on delay. Again I haven't had time to explore this option.

I don't have a working solution yet but I haven't found anyone else that has either.
