Ah, good point, I should have remembered that Gerd offers a CSM bui= ld in
his repo!

So, you can easi= ly look up the build instructions, in Gerd's SeaBIOS and
OVMF= RPM "spec" files. Check out these git repositories:

 https://git.kraxel.org/cgit/jenkins/seabios/
&nb= sp;https://git.kraxel.org/cgit/jenkins/edk2/

S= pecifically:

 https://git.kraxel.org/cgit= /jenkins/seabios/tree/seabios.git.spec
 https://git.krax= el.org/cgit/jenkins/edk2/tree/edk2.git.spec.template

Right, thanks.

Ultimately = it's as simple as:

=E2=80=A2 Build SeaBIOS wit= h CONFIG_CSM
=E2=80=A2 Drop the resulting Csm16.bin into Ovmf= Pkg/Csm/Csm16/ in the EDK2 tree
=E2=80=A2 Build EDK2 with -DC= SM_ENABLE


Thanks David, follow these steps, I can reproduce th= e OVMF-with-csm.fd.
How= ever, I find that when I choose remotes/origin/master branch, after compili= ng, 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 remo= ved CSM support? Could I apply the CSM patch to 
the latest edk2 code to support my work because our project is based on th= e latest EDK2 code, thanks.
Someone else maile= d 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 a= nd into
somewhere more generic, since it really is generic an= d not platform-
specific?

I can't make some decisions, from my = view, maybe CSM module can be 
an independent pa= tch for user to apply or reject :)
