"..\qemu-system-i386w.exe" -m 256 -localtime -drive file=uefi.bin.vhd,format=raw,if=ide,media=disk,index=0 -pflash ..\OVMF.fd -parallel file:para.txt Remember that I am running this in WinXPSP3. Also, the version of OVMF.fd is from http://www.tianocore.org/ovmf/ and I just noticed that that page has been recently changed. You use to be able to download the OVMF.fd directly from that page. It was r15214, which I found out yesterday, is an older version. > > I did find a few RPM files and one of them contained: > > OVMF_CODE-pure-efi.fd > > and > > OVMF_VARS-pure-efi.fd > > Yes, they are from Gerd's "edk2.git-ovmf-ia32" package (since you > mention IA32), from <http://www.kraxel.org/repos/>, and they are > recommended to use. I also could not get these to work.

I will try a few other things and get back with you. Please note that I am using the Windows port of QEMU from https://qemu.weilnetz.de/ on a WinXP host, if that makes any difference. Also, one more question. I can make my GPT image either have a legacy MBR with two entries pointing to one partition each or I can have a Protected MBR that encompasses the whole GPT, both partitions, and the backup items. With the r15214 version and: "..\qemu-system-i386w.exe" -m 256 -localtime -drive file=uefi.bin.vhd,format=raw,if=ide,media=disk,index=0 -bios ..\OVMF.fd -parallel file:para.txt it would boot to the shell either way and load and run my BOOT.efi file just fine, whether I had a Legacy MBR or a PMBR. Does this make a difference with the new image(s) you mention above. Also, please note that the hard drive image is a VHD image, a raw image with a single sector at the end for the VHD info so that Oracles VM Box will boot it. This means that the backup GPT header is *not* the last sector of the disk. The -bios OVMF.fd version boots it just fine in QEMU, but I thought I would mention this in case the new code expects it to be in the last sector. Thank you. I will get back with you on my findings.
