Thanks David, follow these steps, I can reproduce the OVMF-with-csm.fd. However, I find that when I choose remotes/origin/master branch, after compiling, qemu+kvm+ovmf+winxp can't boot up, but when I choose remotes/origin/UDK2018, the compiled OVMF.fd can work. So the latest edk2 code have removed CSM support? Could I apply the CSM patch to the latest edk2 code to support my work because our project is based on the latest EDK2 code, thanks. > Someone else mailed me recently to say they'd copied the Csm packages > over from OvmfPkg to Quark and had Windows booting on Galileo boards. > > Hm, I wonder if we should move the CSM support out of OVMF and into > somewhere more generic, since it really is generic and not platform- > specific? I can't make some decisions, from my view, maybe CSM module can be an independent patch for user to apply or reject :) -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
