| === OVMF OVERVIEW === | |
| The Open Virtual Machine Firmware (OVMF) project aims | |
| to support firmware for Virtual Machines using the edk2 | |
| code base. More information can be found at: | |
| https://edk2.tianocore.org/OVMF.html | |
| === STATUS === | |
| Current status: Alpha | |
| Current capabilities: | |
| * IA32 and X64 architectures | |
| * QEMU (0.9.1 or later) | |
| - Video, keyboard, IDE, CD-ROM, serial | |
| - Runs UEFI shell | |
| * UEFI Linux has booted (but is not stable) | |
| === FUTURE PLANS === | |
| * Stabilize UEFI Linux boot | |
| * Test/Stabilize UEFI Self-Certification Tests (SCT) results | |
| === BUILDING OVMF === | |
| Pre-requisites: | |
| * Build environment capable of build the edk2 MdeModulePkg. | |
| * A properly configured ASL compiler | |
| * Intel ASL compiler: Available from http://www.acpica.org | |
| or | |
| * Microsoft ASL compiler: Available from http://www.acpi.info | |
| Update Conf/target.txt ACTIVE_PLATFORM for OVMF: | |
| PEI arch DXE arch UEFI interfaces | |
| * OvmfPkg/OvmfPkgIa32.dsc IA32 IA32 IA32 | |
| * OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64 X64 | |
| * OvmfPkg/OvmfPkgX64.dsc X64 X64 X64 | |
| Update Conf/target.txt TARGET_ARCH based on the .dsc file: | |
| TARGET_ARCH | |
| * OvmfPkg/OvmfPkgIa32.dsc IA32 | |
| * OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64 | |
| * OvmfPkg/OvmfPkgX64.dsc X64 | |
| Following the edk2 build process, you will find the OVMF binaries | |
| under the $WORKSPACE/Build/*/*/FV directory. The actual path will | |
| depend on how your build is configured. You can expect to find | |
| these binary outputs: | |
| * OVMF.fd | |
| * CirrusLogic5446.rom | |
| More information on building OVMF can be found at: | |
| * https://edk2.tianocore.org/build-ovmf.html | |
| === RUNNING OVMF on QEMU === | |
| * QEMU 0.9.1 or later is required. | |
| * Either copy, rename or symlink OVMF.fd => bios.bin | |
| * Either copy, rename or symlink CirrusLogic5446.rom => vgabios-cirrus.bin | |
| * Be sure to use qemu-system-x86_64, if you are using and X64 firmware. | |
| (qemu-system-x86_64 works for the IA32 firmware as well, of course.) | |
| * Use the QEMU -L parameter to specify the directory where the bios.bin | |
| and vgabios-cirrus.bin files are located. | |
| * Optionally you can use the QEMU -serial command to capture the | |
| OVMF debug messages. For example: -serial file:serial.log | |
| * The EFI shell is built into OVMF builds at this time, so it should | |
| run automatically if a UEFI boot application is not found on the | |
| removable media. | |
