  27 The flash IC is located right next to one of the SATA ports:

  30 ### Internal programming
  31
  32 The main SPI flash can be accessed using [flashrom]. By default, only
  33 the BIOS region of the flash is writable. If you wish to change any
  34 other region (Management Engine or flash descriptor), then an external
  35 programmer is required.
  36
  37 The following command may be used to flash coreboot:
  38
  39 ```
  40 $ sudo flashrom --noverify-all --ifd -i bios -p internal -w coreboot.rom
  41 ```
  42
  43 The use of `--noverify-all` is required since the Management Engine
  44 region is not readable even by the host.
  45
  46 ## Known issues
  47
  48 - There is no automatic, OS-independent fan control. This is because
  49   the Super I/O hardware monitor can only obtain valid CPU temperature
  50   readings from the PECI agent, whose complete initialisation is not
  51   publicly documented. The `coretemp` driver can still be used for
  52   accurate CPU temperature readings.
  53
  54 - me_cleaner breaks LPC bus and attached components!
  55 - PS/2 mouse doesn't work
  56
  57 ## Untested
  58
  59 - parallel port
  60 - EHCI debug
  61 - S/PDIF audio
  62
  63 ## Working
  64
  65 - PS/2 keyboard
  66 - PCIe graphics
  67 - USB
  68 - Gigabit Ethernet
  69 - Integrated graphics
  70 - SATA
  71 - Serial port
  72 - hardware monitor (see [Known issues](#known-issues) for caveats)
  73 - front panel audio
  74 - Native raminit (2 x 2GB, DDR3-1333)
  75 - Native graphics init (libgfxinit)
  76 - Wake-on-LAN
  77 - TPM on TPM-header
