Installation
Installation guide on QEMU: 1. Download this pack on QEMU 6.2.0

2. Download a patched Linaro UEFI 15.12 32-bit and copy this file to the QEMU installation folder.

3. Create a VHD by using the  utility. For this, run the following commands. (Note that these files will be created in a directory on your C drive called "RT", and they will be mounted under the drive letters P and W).

create vdisk file="C:\RT\hdd.vhd" maximum=65536 type=expandable select vdisk file="C:\RT\hdd.vhd" attach vdisk convert gpt create partition efi size=100 format quick fs=fat32 assign letter=p create partition primary format quick assign letter=w exit

4. Apply the  to VHD, and then create boot files:

dism /apply-image /imagefile: /index:1 /applydir:W:\ dism /image:W:\ /set-productkey:NFV72-RG2HG-7FTTP-8FJTB-FF848 /accepteula bcdboot W:\Windows /s P: /f UEFI

After that, eject P or W. Once ejected, P remains and disappears after a reboot.

5. Run QEMU by going to your QEMU installation folder, saving the following text to a batch file, and then running it to start the emulator:

qemu-system-arm ^ -M virt,highmem=false ^ -cpu cortex-a15 ^ --accel tcg,thread=multi ^ -m 2G ^ -bios QEMU_EFI_1512_driver1998.fd ^ -device VGA ^ -device usb-kbd ^ -device usb-tablet ^ -drive id=mydrive,if=none,file=C:\RT\hdd.vhd -device sd-card,drive=mydrive ^ -rtc base=2012-04-24,clock=vm

6. If you want to change the screen resolution, press F2 to enter EFI settings, enter  and then. Change the resolution to the desired one then commit the changes and exit. Choose  in the QEMU menu and then reset the emulator.

'''Important note: The startup process is highly unstable and recovery errors are possible. You must bypass them, to do this, press the Enter key. BSOD errors are also possible. To bypass them, reset the emulator every time you get a BSOD error. After several attempts, you should successfully boot into the system.'''

Hardware compatibility
This is the first build of Windows 8 that drops support for processors without PAE, SSE2 and NX, as running on these processors will result in a black screen with error code 0x5D.

This is the first build to feature the new "Windows 8/RT" branding seen in the RTM.
