 ### coreboot + seabios
 
-To make testing similar to using real hardware, you can build [coreboot] with
-[seabios] payload for "QEMU x86 q35/ich9" machine and run it together with
-rtems-boot.img on QEMU:
+The main and most interesting task of this project is to run the application on
+real hardware. This task can be solved without any problems if you (like us) use
+[coreboot] as BIOS and [seabios] as a payload in your x86 embedded systems.
+Let's test this by building coreboot + seabios image for the "QEMU x86 q35/ich9"
+machine and runn it in QEMU with the virtual disk created at the previous stage:
 
 ```
-qemu-system-i386 -m 128 -bios coreboot.rom -hda rtems-boot.img -M q35 -nographic
+qemu-system-i386 -m 128 -bios coreboot.rom -hda boot-disk.img -M q35 -nographic
 ```
+You can also build coreboot for your board and run real-time applications on it.
