-## Running the coreboot on QEMU
-
-Please keep in mind, that QEMU doesn't implement many of the HW properties,
-that Talos II has. There may be many compatibility issues, or registers missing.
-
-More detailed informations can be found in [porting.md#qemu](porting.md#qemu)
-
-1. Clone the QEMU repository
-   ```
-   git clone [email protected]:qemu/qemu.git
-   # or HTTPS alternatively
-   git clone https://github.com/qemu/qemu.git
-   ```
-2. Build the QEMU ppc64 version
-   ```
-   cd qemu
-    ./configure --target-list=ppc64-softmmu && make
-   ```
-3. Start QEMU with coreboot image
-   ````
-   ./qemu/build/qemu-system-ppc64 -M powernv,hb-mode=on --cpu power9 --bios 'coreboot/build/coreboot.rom' -d unimp,guest_errors -serial stdio -drive file=flash.pnor,format=raw,readonly=on,if=mtd
