+=== BUILDING OVMF ===\r
+\r
+Pre-requisites:\r
+* Build environment capable of build the edk2 MdeModulePkg.\r
+* A properly configured ASL compiler\r
+  * Intel ASL compiler: Available from http://www.acpica.org\r
+      or\r

+Following the edk2 build process, you will find OVMF.fd at:\r

+\r
+=== RUNNING OVMF on QEMU ===\r
+\r
+* QEMU 0.9.1 or later is required.\r
+* Either copy, rename or symlink OVMF.fd => bios.bin\r
+* Be sure to use qemu-system-x86_64, if you are using and X64 firmware.\r
+  (qemu-system-x86_64 works for the IA32 firmware as well, of course.)\r
+* Use the QEMU -L parameter to specify the directory where bios.bin\r
+  is located.\r
+* If QEMU returns an error about not finding a video bios, you can\r
+  try creating an empty copy of the video bios file, or copy the\r
+  video bios from QEMU's BIOS directory.\r
+* Optionally you can use the QEMU -serial command to capture the\r
+  OVMF debug messages.  For example: -serial file:serial.log\r
+* The EFI shell is built into OVMF builds at this time, so it should\r
+  run automatically if a UEFI boot application is not found on the\r
+  removable media.\r
