-* QEMU 0.9.1 or later is required.
-* Either copy, rename or symlink OVMF.FD => bios.bin
+* QEMU 0.12.2 or later is required.
* 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
- file is located.
+* Use OVMF for QEMU firmware (3 options available)
+ - Option 1: QEMU 1.6 or newer; Use QEMU -pflash parameter
+ * QEMU/OVMF will use emulated flash, and fully support UEFI variables
+ * Run qemu with: -pflash path/to/OVMF.fd
+ - Option 2: Use QEMU -bios parameter
+ * Note that UEFI variables will be partially emulated, and non-volatile
+ variables may lose their contents after a reboot
+ * Run qemu with: -bios path/to/OVMF.fd
+ - Option 3: Use QEMU -L parameter
+ * Note that UEFI variables will be partially emulated, and non-volatile
+ variables may lose their contents after a reboot
+ * Either copy, rename or symlink OVMF.fd => bios.bin
+ * Use the QEMU -L parameter to specify the directory where the bios.bin
+ file is located.
* 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.
