Failure to boot BIOS

Hello everyone,

I have a Darter Pro-B laptop from System76, and I attempted to change its BIOS using Coreboot. After making the changes and programming the BIOS onto the IC, my laptop showed no response and wouldn’t boot (only the power LED was on).

Fortunately, I had made a backup of the original BIOS file before making any changes. I reprogrammed the backup file, but the laptop still wouldn’t boot.

The model of my BIOS flash IC is XM25QU256C. Additionally, I should mention that I removed the IC from the motherboard.

I’m unable to attach the original BIOS backup file because I am a new user, and according to the platform’s policy, new users are not allowed to attach files.

Do you have any ideas on what might be causing the laptop not to boot?
Please help me!
