Hi Matt,

I'm still working on it but I've decided to shift the project towards
modeling the AMD V1605B which has vega architecture.
I've the real AMD V1605B device and I'm wondering how could I rip the BIOS
from it. Do you have an idea on how to do it?

I build a custom image with a custom ROCm driver from Bruhnspace and I
suspect that it is now working because them are intendet to work for the
gtx902 gpu, which is the one V1605B has.
Do you think it has something to do with the fact that the BIOS provided in
the gem5 repositories is not exactly that one from the V1605B?

Thank you!

Best Regards,
Pau
