Otherwise I'd be happy to write it up once > I get my head wrapped around it :) Nevermind, it seems it's all under git://git.code.sf.net/p/tianocore/edk2 :) Although the nomenclature is still a bit fuzzy to me, the "thing to build" within edk2 appears to be OvmfPkg (ACTIVE_PLATFORM = OvmfPkg/OvmfPkgX64.dsc, with TOOL_CHAIN_TAG = GCC48, in Conf/target.txt, at least on F20). I now have the latest and greatest "upstream" OVMF.fd, and I can use it (piix only) to boot Fedora 20 live x86_64. Guess I'm on my way :) I get "missing smbios entry point" when I do a dmidecode, BTW. QEMU is sending type 1, 3, 4, etc. blobs in fw_cfg, not sure yet what I need to do to get OVMF to add the entry point... Maybe I should try without my smbios-patched qemu ? Thanks, --Gabriel
