Advice on how to get motherboard model, as the system does not boot? Thanks!...

Bumping this, and attaching the pre- and post-patched dumps that I have. Would really appreciate any advice please!...

Hi everyone,

I've been trying to do this process on a T480. I've followed all the instructions to the letter, dumping the existing BIOS twice, comparing the hashes and then patching one of them. However when I write it back to the system, I'm greeted with a musical tone, which I believe is error 0001 which is stated as "Reset error (platform reset not de-asserted)".

Unfortunately patching the original image back results in the same music and a black screen. I'm pretty stuck on where to go from here, if anyone could offer any advice?

Thanks a l...
