Hello,
I am trying to download the OVMF firmware for QEMU, but I can't find a download link for it. Anyone have a link for it?
Thanks,
nexos

Linux normally has it. So you can install it with the folllowing command:
For Manjaro/Arch:
For Debian/Ubuntu/Mint:
Otherwise you have to build it from source. In that case follow the instructions given on tianocore.org
No matter how you retrieved OVMF, you have to search the file hierarchy for "OVMF.fd".
EDIT: A tip I got from one of OVMF's developers: Run it in Qemu with the
-pflash option, not the
-bios option.

I got it from
https://www.kraxel.org/repos/jenkins/edk2/, I then used
7zFM (7-Zip) for Windows to extract the files needed.

Good point.
Here is how I do it for 64-bit:
Code: Select all
-drive if=pflash,format=raw,unit=0,readonly,file=OVMF-pure-efi.fd
-drive if=pflash,format=raw,unit=1,file=OVMF_VARS-pure-efi.fd
It is the same for 32-bit except you use the 32-bit files instead.

Tell QEMU to load OVMF as the firmware,
like this. Make sure you use a
copy of the VARS file, not the original! You can reuse that copy each time you boot QEMU with the same configuration.
The exact path to the OVMF files depends on the package you installed, but they're probably somewhere under /usr/share (for example, Ubuntu 24.04 has /usr/share/OVMF/OVMF_CODE_4M.fd and /usr/share/OVMF/OVMF_VARS_4M.fd).
