Right, thanks. Ultimately it's as simple as: • Build SeaBIOS with CONFIG_CSM • Drop the resulting Csm16.bin into OvmfPkg/Csm/Csm16/ in the EDK2 tree • Build EDK2 with -DCSM_ENABLE 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? -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
