Hello there.

I would like to downgrade my old Asus laptop bios. When I tried from current bios , it says it s too old to upgrade (obviously) .

I was thinking if I could force flashing an old version bios:

$ sudo ./flash yourrom.rom

But my bios file is a "cap" extension.

I was searching a coreboot bios but I couldn't find anything:

https://www.coreboot.org/Laptop#Laptops_with_coreboot_Support

I m using trisquen 7 64

Thank you

Very few motherboard models have coreboot support, and you have to use an external programmer to flash them on most supported motherboards.

Downgrading the firmware version is usually prohibited on most systems, for "security" reasons. Again, an external programmer is required.
