Thanks to noldrin.
Now you can update your Blag 90001 x86_64 from this repository:
To do it, modify the /etc/yum.repos.d/blag.repo file:
yum clean all
kernel-libre-firmware noarch packages seems not to be on the repository for now. So if you have troubles with that you can download the package that match your kernel on the FSFLA server here:
Don't forget to download the package which match the kernel you are installing.
Noldrin told us the repository works for blag x86_64 net install with the iso on his server:
I think it'd work too with the blag x86_64 netinstall iso you can download from Blag website.
