2 === OVMF OVERVIEW ===
\r
4 The Open Virtual Machine Firmware (OVMF) project aims
\r
5 to support firmware for Virtual Machines using the edk2
\r
6 code base. More information can be found at:
\r
8 https://edk2.tianocore.org/OVMF.html
\r
12 Current status: Alpha
\r
14 Current capabilities:
\r
15 * IA32 and X64 architectures
\r
16 * QEMU (0.9.1 or later)
\r
17 - Video, keyboard, IDE, CD-ROM, serial
\r
19 * UEFI Linux has booted (but is not stable)
\r
21 === FUTURE PLANS ===
\r
23 * Stabilize UEFI Linux boot
\r
24 * Test/Stabilize UEFI Self-Certification Tests (SCT) results
\r
26 === BUILDING OVMF ===
\r
29 * Build environment capable of build the edk2 MdeModulePkg.
\r
30 * A properly configured ASL compiler
\r
31 * Intel ASL compiler: Available from http://www.acpica.org
\r
33 * Microsoft ASL compiler: Available from http://www.acpi.info
\r
35 Update Conf/target.txt ACTIVE_PLATFORM for OVMF:
\r
36 PEI arch DXE arch UEFI interfaces
\r
37 * OvmfPkg/OvmfPkgIa32.dsc IA32 IA32 IA32
\r
38 * OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64 X64
\r
39 * OvmfPkg/OvmfPkgX64.dsc X64 X64 X64
\r
41 Update Conf/target.txt TARGET_ARCH based on the .dsc file:
\r
43 * OvmfPkg/OvmfPkgIa32.dsc IA32
\r
44 * OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64
\r
45 * OvmfPkg/OvmfPkgX64.dsc X64
\r
47 Following the edk2 build process, you will find the OVMF binaries
\r
48 under the $WORKSPACE/Build/*/*/FV directory. The actual path will
\r
49 depend on how your build is configured. You can expect to find
\r
50 these binary outputs:
\r
52 * CirrusLogic5446.rom
\r

55 * https://edk2.tianocore.org/build-ovmf.html
\r
57 === RUNNING OVMF on QEMU ===
\r
59 * QEMU 0.9.1 or later is required.
\r
60 * Either copy, rename or symlink OVMF.fd => bios.bin
\r
61 * Either copy, rename or symlink CirrusLogic5446.rom => vgabios-cirrus.bin
\r
62 * Be sure to use qemu-system-x86_64, if you are using and X64 firmware.
\r
63 (qemu-system-x86_64 works for the IA32 firmware as well, of course.)
\r
64 * Use the QEMU -L parameter to specify the directory where the bios.bin
\r
65 and vgabios-cirrus.bin files are located.
\r
66 * Optionally you can use the QEMU -serial command to capture the
\r
67 OVMF debug messages. For example: -serial file:serial.log
\r
68 * The EFI shell is built into OVMF builds at this time, so it should
\r
69 run automatically if a UEFI boot application is not found on the
\r
