I have a z64 HW2 with 2.20 Bios installed.

Can I reflash and downgrade the bios to 2.18 or will it not work?

Many thanks

I would think that you could if you had that BIOS on there previously. But you should be careful when changing BIOS. If the BIOS gets trashed the machine could become useless or need electronic skills to repair.

I downgraded from 2.18 to 2.17 years ago, that worked fine.
