 the video information correctly (it always says the resolution is 0x0). This
 works correctly for link though.
 
+You can run via QEMU using::
+
+  qemu-system-x86_64 -bios build/coreboot.rom -serial mon:stdio
+
+The `-serial mon:stdio` part shows both output in the display and on the
+console. It is optional. You can add `nographic` as well to *only* get console
+output.

+To run with a disk-image file called `$DISK`::
+
+  qemu-system-x86_64 -bios build/coreboot.rom -serial mon:stdio \
+	-drive id=disk,file=$DISK,if=none \
+	-device ich9-ahci,id=ahci \
+	-device ide-hd,drive=disk,bus=ahci.0
+
+Then you can scan it with `scsi scan` and access it normally.

+To use 4GB of memory, typically necessary for booting Linux distros, add
+`-m 4GB`.
