It is all more or less clear to me in the install docs, however I am not sure how to gather info about my hardware, which modules should be compiled when installing kernel manually. Is there a way to gather this info? What command should be issued to accomplish that? Also, I am sort of reluctant to compile kernel manually. Is this possible to use genkernel to install system in EFI mode or I must to use manual compilation? Thank you for your advice and suggestions.
