## Schemat blokowy
## Linux
Trzeba ściągnąć jądro i obraz dysku z [Debian on Malta](https://people.debian.org/~aurel32/qemu/mips/), a potem odpalić:
```
qemu-system-mips -M malta \
-kernel vmlinux-3.2.0-4-4kc-malta \
-hda debian_wheezy_mips_standard.qcow2 \
-append "root=/dev/sda1 console=tty0" \
-net user,hostfwd=tcp::10022-:22 -net nic \
-device usb-mouse -device usb-kbd \
-soundhw es1370
```
Z maszyną wirtualną można się łączyć po ssh `ssh -p10022 root@localhost`.
