Can I restore original Dreamcast Bios?

[Versatile]

Let's say I install dreamshell to the bios so now that is my default bios. Can I restore it somehow to go back to the original dreamcast bios?

Just flash another original bios in DSInstall app or switch bios if you have 2 bios chips.

I try to install the dreamshell bios and it says something about failed. Why is that?

How do you flash the bios in the first place? Does it install itself from the dreamshell cd? I tried to pick the first option Dreamshell bios, and it says something about fail.

Do you need to solder a special chip to the motherboard or what?
